Results Of Insomnia Studies

Results of insomnia studies are focusing on all angles of insomnia. We know for some time that the circadian rhythm is linked to deep REM sleep, which we only reach about 2 hours into our nightly sleep. There are several reasons why our normal sleep pattern can get disrupted.

1. Night owls have a CRY1 mutation

A recent publication on March 27, 2017 has detected a mutation of the human circadian clock called CRY1. This is a dominant gene that is responsible for delayed sleep phase disorder (DSPD). People with this genetic feature tend to go to sleep 2 hours later than the average person every day.

It occurs between 0.2% and 10% in the general population and is inherited by the autosomal dominant mode.

This gene is responsible for the phenomenon of persons being “night owls”.

2. Sleep deprivation in nursing homes

Another publication has zeroed in to what happens in the frail elderly who live in nursing homes.

Here is what sleep researchers have found out about nursing homes.

  • Older people also need 7 to 8 hours of sleep per night, not less as previously thought.
  • Let people sleep at night, and give them undisturbed sleep. The practice of waking them up every 2 hours is unnecessary and undermines a restful sleep with normal amounts of REM sleep.
  • The color of light matters: Blue/purple light coming from TVs, iPod’s, laptops or cell phones stimulates serotonin production that wakes you up. In contrast to this orange/red light stimulates melatonin production that facilitates sleep. A nursing home owner, Guildermann said: “We have made it darker at night, and what light they do have is orange/amber/red light, and we are having phenomenal results.”
  • Sleep, exercise and nutrition are the biggest components of health.

3. Night workers

One of the news stories in 2016 was about health risks of night shifts. The Bureau of Labor Statistics reported in 2000 that 15 million workers (16.8 % of the working population) were doing alternative shifts (night shift work mixed with daytime shifts). In 2016 they reported 14.8% were working alternate shifts. Among blacks, Asians and Latino Americans the percentage of working alternative shifts was higher, namely 20.8%, 15.7% and 16%, respectively.

Shift work is more common in certain industries, such as protective services like the police force, food services, health services and transportation.

Your body rewards you, when you sleep 7 to 8 hours during the night, but it will penalize you severely, if you turn it upside down. The reason is the diurnal hormone rhythm that we all have built in. Sleep is regulated by melatonin during the night, which is released by the pineal gland (on the base of the skull). Daytime wakefulness is regulated by the stress hormone cortisol from the adrenal glands. These two hormones inhibit each other, cortisol inhibits melatonin and melatonin inhibits cortisol. All the other hormones are also regulated according to the diurnal rhythm: testosterone, for instance is highest in the morning, human growth hormone is highest between midnight and 3 AM.

There are examples of what happens when you do shift work for several years:

  1. A) A Swedish study found that white-collar shift workers had a 260% higher mortality compared to a control group of daytime white collar workers: Shift work and mortality.
  2. B) A study compared night workers in the age group of 45 to 54 with daytime workers and found a 147% higher mortality rate in the night shift workers: Shift Workers’ Mortality Scrutinized. Shift workers work at night and sleep during the day. This can be done, but it is against the physiology of your body, as I explained above. Remember that melatonin does not only regulate your sleep, it also is one of the main stimulant hormones of the immune system. If you manipulate your diurnal hormone rhythm by staying awake during the night and sleeping during the day, you pay the price by an increased risk of mortality (increased risk of death). I think this is not worth it!

4. What to do when you cannot sleep?

The first step is to take 3mg to 5mg of melatonin at bedtime. It should be taken between 10PM and 11PM. It takes 20 to 30 minutes for melatonin to take effect. If you do not fall asleep within that time frame you are likely thinking too much! Relaxation before going to sleep should be part of your evening ritual. It can happen that we experience demanding, stressful days, and despite all better effort, it is difficult to be entirely relaxed. After demanding days like that I would recommend taking 1 or 2 capsules of valerian (500 mg strength) from the health food store. This combined with the melatonin should help in more than 80%-90% of insomnia cases. If you cannot sleep, see your physician. Sleep studies may be required or you may have problems of the thyroid (hypo- or hyperthyroidism), which may need to be checked. Other medical problems including depression have to be checked out as well. Melatonin and valerian are safe. Other sleeping pills have multiple side effects including memory problems the next day or the feeling of a mild hangover.

5. Telomeres and insomnia

Some people have no problem disciplining themselves to go to sleep between 10PM and 11 PM, which seems to be the window of opportunity to catch a good night’s sleep. Others are so used to do their late night activities (reading, watching TV, being online, going to the pub etc.) that they finally drop into bed at 1 or 2 AM. People need 7 to 8 hours of good sleep; even hard-core party goers need to get that much sleep. Nature does not make exceptions! When you go to bed only at 1AM or 2AM, it is difficult to get enough sleep.

It is true that you can suffer multiple health problems, as all of your hormones depend on the resetting during your deepest sleep between 2AM and 4AM triggered by the nighttime melatonin response. Even your telomeres, the caps of chromosomes in every cell get shortened from too much stress and too little sleep. Shortened telomeres mean a shortened life span. The reason for this is that people with shortened telomeres develop heart attacks, strokes and cancer. This is what shortens the life span. How do we avoid this risk? Go back to healthy sleep habits. As mentioned above it is best to start going to sleep between 10 PM and 11 PM and sleep for 7 to 8 hours.

6. Electronics in the bedroom

There is new research showing that electronics in the bedroom can interfere with a normal sleep pattern. Dr. Ben Carter is the lead author and a senior lecturer in biostatistics at King’s College London. He completed a study involving 125,198 children with an average age of 14½ years. There were about equal amounts of males and females. Both sexes had the same problem. When they were allowed to use electronic media, this interfered with their sleep time. What electronic devices are we talking about? Watching TV, using the computer, the cell phone, tablets and computer games. The study was originally published at JAMA Pediatrics.

The blue/purple light of the TV screen or a computer screen stimulates the brain to produce serotonin. This undermines the melatonin production and as a result the person finds it extremely difficult to fall asleep.

Here is a list that contributes to better sleep habits and better sleep quality:

  • Ensure that the bedroom is dark, soundproof, and comfortable with the room temperature being not too warm. It is important to develop a “sleep hygiene”. This means going to sleep around the same time each night, to have some down time of 1 hour or so before going to bed and getting up after the average time of sleep (for most people between 7 to 9 hours). Sleeping in is not a solution, and an alarm clock will also help to develop a sleep routine.
  • Caffeine drinks, alcohol, nicotine and recreational drugs must be avoided. Smokers should butt out no later than 7PM, as nicotine is a stimulant.
  • Getting into a regular exercise program, either at home or at a gym is beneficial.
  • Avoid a heavy meal late at night. A light snack including some warm milk would be OK.
  • It is not a sensible idea to use the bedroom as an office, reading place or media center. It paves the way to the getting stimulated by cortisol, which keeps us awake. The bedroom is a place of rest and should be comfortable and relaxing.
  • Some sleepers wake up at night, and they are wide-awake! Leaving the bedroom and relaxing in the living room for a while can help. It goes without saying that playing video games will not help! An alternative is to take 3 mg of melatonin, which will helps to fall asleep faster, but melatonin will wear off after about 4 hours.
  • A self-hypnosis recording is a useful adjunct to a sleep routine. Listening to it before going to sleep helps to focus on relaxation and to stop ruminating about the day and its events. Keep the volume low.

Results Of Insomnia Studies

Conclusion

Recent results of insomnia studies have reconfirmed that we need our regular sleep to maintain our health. We have seen that some nursing homes have a practice of waking the client up every 2 hours. This must be abandoned as it interferes with the restorative deep REM sleep. In turn this will interfere with hormone restoration overnight.

Children and adolescents must limit their time in front of the TV, iPhones and computer screens. The blue light has the frequency that over stimulates the brain and interferes with melatonin production. Some people work overnight as shift workers or party until the wee hours in the morning. This causes your telomeres in your body cells to shorten. When you restore your sleeping pattern to normal your telomere length will no longer be shortened.

Even people who are night owls due to an inborn CRY1 gene that is responsible for delayed sleep phase disorder can normalize their sleep pattern by following a strict sleep hygiene. As people get older they lose the ability to make melatonin, but this can be replaced by taking melatonin tablets at bedtime.

Remember what I said earlier: Sleep, regular exercise and good nutrition are the biggest components of health.

Electronics In The Bedroom

There is new research showing that electronics in the bedroom can interfere with a normal sleep pattern. Dr. Ben Carter is the lead author and a senior lecturer in biostatistics at King’s College London. He just completed a study involving 125,198 children with an average age of 14½ years. There were about equal amounts of males and females. Both sexes had the same problem. When they were allowed to use electronic media, this interfered with their sleep time. What electronic devices are we talking about? Watching TV, using the computer, the cell phone, tablets and computer games. The study was originally published at JAMA Pediatrics.

Result of the study on electronics in the bedroom

  1. When media bedtime use was allowed, there was a 2.17-fold higher risk of not getting enough sleep quantity. This was compared to kids who did not use media devices in the bedroom.
  2. There was a 1.46-fold risk of having poor sleep quality.
  3. There was a 2.72-fold risk of excessive daytime sleepiness.
  4. Even children who had access to media use, but did not use it at night had similar findings. They had a risk of 1.79-fold to get inadequate sleep quantity. There was a 1.53-fold risk of poor sleep quality. And excessive daytime sleepiness was present with a 2.27-fold risk.

Melatonin level influenced by electronics in the bedroom

The diurnal hormone rhythm has been well researched regarding our sleep pattern. Essentially two hormones work together.

In the morning when you open your eyes, light enters our eyes and is registered in the hypothalamus. There are also links from the hypothalamus to the pineal gland, where melatonin is synthesized and stored. The light signal stops the secretion of melatonin from the pineal gland, although it is still being produced during the day in the pineal gland, but stored there until the evening hours set in. You may have noticed that you start yawning when the light dims in the evening. That’s when melatonin is released into your system to let you know it’s time to slow down and go to sleep.

Of course, we have electrical light and can turn night into day if we choose to! This works for a limited time, but eventually tiredness sets in, and melatonin wins the upper hand. Melatonin is the master hormone of the circadian rhythm.

It is interesting to note that cortisol does exactly the opposite. Cortisol is the adrenal gland hormone that helps us cope with stress. When we are fully awake, we need cortisol to cope with the various stress situations of the day. Melatonin inhibits cortisol secretion and cortisol inhibits melatonin secretion, and they are natural opponents working together for your common good. This is part of the circadian rhythm. We can measure these hormones, and this is how researchers have found out how these two hormones work together.

When children or adults expose themselves too much to electronic devices, the brain gets stimulated and sends signals to the adrenal glands to produce more cortisol. In between the hypothalamus and the adrenal glands there is a cascade of hormones that are involved in this.The hypothalamus sends CRH, the corticotropin-releasing hormone to the pituitary, which stimulates in turn the release of the messenger hormone ACTH to produce more cortisol in the adrenal glands. It is the extra cortisol that keeps kids awake. The same applies to adults who invite electronics into their bedroom. All the excitement from watching the various media gadgets leads to extra cortisol. And we just learnt that cortisol counteracts melatonin. 

What can parents do about electronics in the bedroom?

First of all, parents need to be firm with their kids. They need to explain to them that electronics need to be kept out of the bedroom. There needs to be a cooling down period one hour before bedtime where they do not watch TV, use the cell phone or other electronic gadgets. They may rebel against this first, but when they sleep better, they likely will be more agreeable. Here is a list that contributes to better sleep habits and better sleep quality:

  • Ensure that the bedroom is dark, soundproof, and comfortable with the room temperature being not too warm. It is important to develop a “sleep hygiene”. This means going to sleep around the same time each night, to have some down time of 1 hour or so before going to bed and get up after the average time of sleep (for most people between 7 to 9 hours). Sleeping in is not a solution, and an alarm clock will help also to develop a sleep routine.
  • Caffeine drinks, alcohol, nicotine and recreational drugs must be avoided. Smokers should butt out no later 7PM, as nicotine is a stimulant.
  • Getting into a regular exercise program, either at home or at a gym is beneficial.
  • Avoid a heavy meal late at night. A light snack including some warm milk would be OK.
  • It is not a sensible idea to use the bedroom as an office, reading place or media center. It paves the way to the stimulus of the cortisol effect that keeps us awake. The bedroom is a place of rest and should be comfortable and relaxing.
  • Some sleepers wake up at night, and they are wide-awake! Leaving the bedroom and relaxing in the living room for a while can help. It goes without saying that playing video games will not help! An alternative is to take 3 mg of melatonin, which will helps to fall asleep faster, but melatonin will wear off after about 4 hours.
  • A self-hypnosis recording is a useful adjunct to a sleep routine. Listening to it before going to sleep helps to focus on relaxation and to stop ruminating about the day and its events. Keep the volume low.

Some thoughts about sleep aids after electronics in the bedroom are removed

Sometimes an adolescent will have trouble falling asleep. Here is the solution of what to do: at the time the youngster is having problems sleeping, there is too much cortisol on board, which prevents the melatonin from being released from the pineal gland. What is missing is melatonin.

The first step is to take 3mg of melatonin at bedtime. It takes 20 to 30 minutes for melatonin to take effect. If the youth does not fall asleep within that time frame he or she is likely thinking too much. If that were the case, I would recommend taking 1 or 2 capsules of valerian root (500 mg strength) from the health food store. This combined with the melatonin should help in more than 80%-90% of insomnia cases. If the child still cannot sleep, see your physician. The adolescent may need sleep studies done or may have problems with the thyroid (hypo- or hyperthyroidism), which may need to be checked. Other medical problems, including depression, have to be checked out as well. Melatonin and valerian are safe. Other sleeping pills have multiple side effects including memory problems.

Electronics In The Bedroom

Electronics In The Bedroom

Conclusion

A new study has shown that electronics in the bedroom will often keep children awake. It has become a huge problem in schools where students fall asleep or have problems paying attention. There are simple rules regarding a quiet bedroom without electronics that will go a long way of rehabilitating a child who has sleeping problems because of electronics. There are natural ways to help nature along, if the simple measures don’t work. Melatonin and valerian root help to calm the mind and help catching some healthy sleep. If the problem were persisting, an appointment with the family physician would be in order.

Even though this article deals with children and adolescents and the use of electronics in the bedroom, the same applies to adults. They are not immune to the stressors that disrupt sleep. They are just as likely to feel tired and sluggish after a restless sleep, and their performance at the workplace will suffer. Sleep hygiene is as important for adults as it is for adolescents.

Health Risks Of Night Shifts

One of the news stories in 2016 was about health risks of night shifts. The Bureau of Labor Statistics reported in 2000 that 15 million workers (16.8 % of the working population) were doing alternative shifts (night shift work mixed with daytime shifts). In 2016 they reported 14.8% were working alternate shifts. Among blacks, Asians and Latino Americans the percentage of working alternative shifts was higher, namely 20.8%, 15.7% and 16%, respectively.

Shift work is more common in certain industries, such as protective services like the police force, food services, health services and transportation.

Evidence of health risks of night shifts

There are several publications that showed evidence of health risks of night shift workers. Here is a random selection to illustrate the health risks of night shifts.

  1. A study from 2015 examined the sleep patterns of 315 shift nurses and health care workers in Iranian teaching hospitals. They found that 83.2% suffered from poor sleep and half of them had moderate to excessive sleepiness when they were awake.
  2. This South Korean study examined 244 male workers, aged 20 to 39 in a manufacturing plant. Blood tests from daytime workers were compared to night shift workers. Inflammatory markers like the C-reactive protein and leukocyte counts were obtained. Night shift workers had significantly higher values. The investigators concluded that shift workers have increased inflammatory markers. This is a sign of a higher risk of developing cardiovascular disease in the future.
  3. A Swedish study found that white-collar shift workers had a 2.6-fold higher mortality over a control group of daytime white-collar workers.
  4. Another study compared night workers in the age group of 45 to 54 with daytime workers and found a 1.47-fold higher mortality rate in the night shift workers.
  5. In a study from China 25,377 participants were included in a study that investigated cancer risk in males with more than 20 years of night shift work. They had a 2.03-fold increased risk to develop cancer compared to males working day shifts. Women with night shift work were unaffected with regard to cancer.
  6. A Polish study examined hormones and the body mass index (BMI) among 263 women who worked night shifts and 269 women who worked day shifts. When night shift workers had worked more than 15 years at nights, their estrogen levels, particularly in postmenopausal women were elevated compared to the daytime workers who served as controls. The BMI was also increased in the nighttime workers.
  7. Chronic lymphocytic leukemia (CLL): a study in Spain showed that working for more than 20 years in rotating night shifts was associated with a 1.77-fold higher risk of developing CLL. The authors noted that melatonin levels in that group were much lower than in controls that worked only day shifts. Working in straight night shifts did not show higher risks of CLL compared to daytime workers.
  8. In a Korean study from Seoul 100 female medical technologist who worked nighttime had their melatonin levels tested, which were compared to daytime workers.  They measured 1.84 pg/mL of melatonin for the nighttime workers compared to 4.04 pg/mL of melatonin in the daytime workers. The authors felt that this is proof that the diurnal hormone system has been disrupted. When the melatonin level is altered, the circadian hormone rhythm is also changed.
  9. A group of 168 female hospital employees doing rotating nightshift work in Southern Ontario hospitals were compared to 160 day workers. Cortisol production was assessed. Cortisol production in day workers and in shift workers on their day shift was similar. However, shift workers on their night shift had flatter cortisol curves and produced less cortisol. The authors felt that this disruption of cortisol production would explain why rotating night shift workers have a higher risk of cardiovascular diseases.
  10. A Danish study with female nurses followed 28,731 nurses between 1993 and 2015. Daytime nurses were compared to rotating nighttime nurses and the incidence of diabetes was measured. Night shift workers had a risk between 1.58-fold to 1.99-fold when compared to daytime workers to develop diabetes. The risk for evening shift workers was less (between 1.29-fold and 1.59-fold).

Diurnal hormone rhythm behind health risks of night shifts

Your body has its own rules. It rewards you, if you sleep 7 to 8 hours during the night, but it will penalize you severely, if you turn it upside down. The reason is our built-in diurnal hormone rhythm. A peak of melatonin regulates sleep during the night. Melatonin is released by the pineal gland (on the base of the skull) when it gets dark outside. Daytime wakefulness is regulated by the stress hormone cortisol from the adrenal glands. These two hormones inhibit each other, cortisol inhibits melatonin and melatonin inhibits cortisol. All the other hormones are also regulated according to the diurnal rhythm: testosterone is highest in the morning, human growth hormone is highest between midnight and 3 AM etc.

When you work daytime shifts, your diurnal hormone rhythm is unchanged. But if you work night time shifts, your hormones have to adapt. This is very similar to traveling east or west where you cross several time zones. Your internal diurnal hormone system has to adjust to these changes. Typically it takes 1 day to adjust to a 1-hour time zone difference.

In people who work permanent night shifts, the hormone changes stay adjusted and there is no further switching. But most employers want to be “fair” to everybody, so they introduced the rotating night shifts, which as all the publications cited above show is the worst thing you can do. It messes with your diurnal hormone rhythm, and some people never switch completely to the new hours worked. They don’t get enough daytime sleep because the kids are loud during the day etc. The rotating shift workers are running the highest risk of getting cancer, diabetes, cardiovascular diseases, obesity, cancer, leukemia, and they have low levels of melatonin.

Health Risks Of Night Shifts

Health Risks Of Night Shifts

Conclusion

When shift workers work constant night shifts, this is less stressful to our system than the more common rotating shift work. This is where you work night shifts for a period of time, then the schedule switches to day shift, and you keep on rotating. The least health risks are associated with regular daytime work. People exposed to rotating night shifts suffer from poor sleep. They have a higher risk of gaining weight, getting obese and acquiring diabetes in time. They are at a higher risk for heart attacks, strokes and cancer. All-cause mortality is about twofold higher than for workers who work day shifts.

The underlying problem seems to be a disturbance of the diurnal hormone rhythm. Normally this regulates our waking/sleeping rhythm and keeps us healthy. But with nighttime work melatonin production weakens, cortisol production is reduced and hormone rejuvenation during rest periods suffers greatly. This weakens the immune system, allows cancer to develop and leads to chronic inflammation causing cardiovascular disease and diabetes. The remedy to prevent this from happening is to catch little naps whenever you can during the day and, if at all possible, work daytime shifts permanently.

LED Streetlights Can Be Harmful

The American Medical Association (AMA) has just released a new policy recommendation and statement that LED streetlights can be harmful. After meticulous reviews of the research on the effect of white LED streetlights and their effect on health the AMA decided that it needed to publish its recommendations so that city fathers have some guidelines for illuminating their cities.

Cost and energy savings from white streetlights

Many cities in the US have already switched from the yellowish traditional streetlights to the high-intensity LED lighting. This was done unilaterally without consulting of health professionals or the public. The cities wanted to save money by using white LED lights. But as we will discover below there are serious health consequences to this.

Historic lighting solutions

We did not always have streetlights. The intensity of light is measured by the Kelvin units (K). The color composition is called the “color temperature” (CT). Before electricity was invented we burnt candles and wood at night. This produced a light of 1800 K, which was yellow and red with hardly any blue. Next came incandescent light bulbs. They have a color temperature of 2400 K, which contains less blue and more yellow and red. The new light source is the LED light, which contains a lot more blue color and appears to us as white light. The color temperature is around 4000 K to 5000 K.

LED streetlights can be harmful to your health

Who would have thought that switching streetlights could have anything to do with your health? The newest LED street lights are emitting large amounts of blue light. Our eyes perceive this as white light, but it also creates night-time glare, much more so than conventional lighting. Eye discomfort from blue-rich LED lighting can interfere with visual acuity and cause road hazards. However, this is not all. The blue-rich LED streetlights happen to operate at the wavelength that suppresses melatonin during the night. It has been estimated that the white LED lamps cause interference with the important circadian sleep rhythm. This effect is much stronger with the white LED lights compared to the conventional streetlights. The interference with the sleep rhythm means that there is less sleep time. Sleep quality is perceived to be unsatisfactory. There is daytime sleepiness and impaired daytime functioning. White light LED lights can even cause obesity.

Animals can also be affected by white LED light. The bright outdoor LED lights disturb many species that need a dark environment. Poorly designed LED lighting disorients some birds. Insects, turtles and certain fish species have also been found to be disturbed in their habitat by white LED lights. US national parks have adopted lighting designs that reduce the effects of light pollution on wildlife. So far nobody has shown any concern, what light pollution does to humans!

AMA guidelines to reduce impact of white LED lights

The AMA has come out with new guidelines to help reduce the impact of white LED light. Instead of high-intensity white streetlights the AMA recommends to communities to use the lowest emission of blue light possible to reduce glare. The AMA has recommended a color temperature of no more than 3000 K. This type of light has more of a mix of blue, green, yellow and red in it and very little white. In contrast the CT of bright LED streetlights have 4000 K to 5000 K. This contains a lot of blue light, which appears as white to the eye. Seattle and New York belong to the cities that recently had their streetlights retrofitted to the white LED streetlights. According to the AMA guidelines these lights should now be refitted again. The AMA also recommends that the lights should be shielded to minimize glare and the detrimental effect on humans and the environment. There should also be a possibility of dimming the lights in off-peak periods.

Evidence from medical literature that LED streetlights can be harmful

Here I am reviewing what has been found in the medical literature about white LED lighting that is now preferably used in street lighting.

  1. A Chinese lab tested epithelial cell lines derived from human lenses under a variety of light sources. The lab had previously established that oxidative stress on epithelial cells from human lenses was the most important factor for developing cataracts in humans. Human epithelial cells were cultured in the presence of different LED light frequencies. A high color temperature of 7378 K caused damage to the epithelium while controls of lower color temperatures of 2954 K and 5624 K LED lights did not. The authors concluded that white LED light with a high color temperature could cause significant photobiological damage to human lens epithelial cells. This in turn can cause cataracts and legal blindness.
  1. Another research group studied human epithelial pigment retinal cells in tissue culture. They exposed the tissue cultures to various light frequencies, namely white, blue, green or red LED light. Reactive oxygen and DNA damage were assessed. The white light showed the highest amount of damage to the human retinal cell in culture.
  1. In a trial on senior long-term care home residents researchers found that intermittent exposure to bright light (versus red light) showed positive cognitive effects on the seniors. It is not clear why with respect to cognitive function there is a positive finding using white LED lights, while the other tests mentioned above showed negative effects on the lens and the retina of the eyes.
  1. In another investigation blue light filters were employed in night shift workers and the investigators detected beneficial health effects. In animal experiments the same results were found.

Normally in shift workers cancer, heart disease, metabolic disturbances, depression, anxiety disorders and reproductive problems are found.

LED Streetlights Can Be Harmful

LED Streetlights Can Be Harmful

Conclusion

Despite the evidence in the medical literature showing that yellow lights are better than the newer white LED lights, cities have been converting the yellow streetlights to white LED streetlights. It makes economic sense, but harms people. The American Medical Association is attempting to convince authorities to use common sense. The AMA wrote guidelines and hopes that city fathers will reconsider their decisions. If you are concerned, voice your opinion by talking to your political representative.

Sleeping Habits

When you are a child or a youngster sleeping habits are rarely a problem. But as people age, they tend to have problems falling asleep and sleeping through the night. Older people may also have certain hormone deficiencies, which can contribute to a change in sleeping habits.

Some basics regarding sleeping habits

There are a couple of facts that everybody should know about sleep, so you work with nature, not against it.

  1. The way our bodies are hardwired, we need 7 to 8 hours of sleep and we need to fall asleep between 10PM and 11PM.
  2. The reason for the relative rigid sleeping schedule time wise is the diurnal hormone rhythm. This is also known as the circadian clock that is dictated by the light of the sun (24 hour cycle). Light going into our eyes in the morning inactivates melatonin. But in the evening the pineal gland releases melatonin after sunset. This is what keeps the internal clock on time. We all know how we derail when we fly east or west. There are differences. I find that I am more affected when I fly west than east. The readjustment for me often takes one or two weeks for a 9-hour time zone difference.
  3. Melatonin is gradually produced less as we age. The highest melatonin production occurs around 10 years of age. From then on melatonin production declines. This likely is the reason why older people more often have insomnia problems.
  4. There is interplay between melatonin and cortisol. These two hormones complement each other. When you sleep melatonin governs and resets the hormones to be ready in the morning. This involves an early testosterone peak for the male and cortisol, which has to be ready the moment you wake up. It is cortisol coming from the adrenal glands that rules during the day and is giving us energy. Thyroid hormones also give you energy during the day. As I will explain below, human growth hormone is an energy-giving hormone as well that also clears your mind.
  5. What is not as much known is that human growth hormone (GH) provides energy for us. Growth hormone is released as a spurt between midnight and 3 AM, when you’re deep asleep. The purpose of that is to get you ready with regard to energy for the next day. If you drink alcohol after 5PM the afternoon before, you will miss most of that GH spurt during the night and have a hangover (lack of energy the following day).  At the 23 rd Annual World Congress on Anti-Aging Medicine on Dec. 13, 2015 in Las Vegas the endocrinologist, Dr. Thierry Hertoghe from Belgium gave a talk about GH and said that even one drink during the evening before you go to sleep will cancel 75% of the GH spurt causing a lack of energy the following day. When you have alcoholic drinks evening after evening as many people do, you interfere with your deepest sleep, creating a fitful sleep and you can develop GH deficiency, which can be measured with blood and urine tests. GH deficiency leads to premature signs of aging, such as wrinkles, musculoskeletal problems, muscle weakness and dementia. Many people in their 80’s look “old”. In fact they may be growth hormone deficient and could be treated with human GH, if GH deficiency were confirmed by tests. Part of the aged appearance is reversible in cases of growth hormone deficiency by treating with daily GH injections.
  6. As we age, we produce less melatonin and less growth hormone. All of these hormone levels can be determined. If they are low, they should be replaced with small amounts of whatever hormone is missing.
  7. There are other hormones that are important for energy: cortisol from the adrenal glands, thyroid hormones and DHEA from the adrenal glands. When people get older there is a problem with melatonin production and an evening dose of melatonin supplement of 3mg is advisable. People beyond the age of menopause (females) and andropause (males) need bioidentical sex hormone replacement. Once they have sufficient hormone levels, they will also have more energy. It is advisable to get all of these hormones tested using a saliva hormone test. Growth hormone is a bit more difficult to assess, but IGF-1 levels give a first indication what your growth hormone levels are doing. The newest test is a 24-hour urine collection or an overnight urine sample looking for growth hormone metabolites. If levels are found to be low, daily replacement of growth hormone using a pen similar to insulin injections in diabetics can be given, using pure human growth hormone. You would need to seek the advice of a knowledgeable naturopath.

What does insomnia do to you?

From a psychological point of view performance is slower, there is a slower reaction time and there is a risk of developing anxiety or depression. The immune system gets weakened, high blood pressure can develop and there is a risk of developing heart disease, diabetes and cancer. It is common to gain weight becoming overweight or obese. Even your telomeres, the caps of chromosomes in every cell get shortened from too much stress and too little sleep. Shortened telomeres mean a shortened life span.

How to improve sleeping habits

Set your alarm clock for 8 hours later when you go to sleep. Make sure your bedroom is dark, but wake up to the alarm clock after 7 to 8 hours of sleep. Don’t sleep longer than 8 hours per night. Your internal diurnal hormone rhythm will thank you for regulating your sleep/wake rhythm by giving you the energy you want. I enjoy mine.

Sleeping habits include problems falling asleep or sleeping through

Falling asleep: As we mostly have a lack of melatonin, the first step is to take 3mg to 5mg of melatonin at bedtime. But it should be taken during the window of opportunity fitting into the diurnal hormone rhythm as mentioned above: between 10PM and 11PM. It takes 20 to 30 minutes for melatonin to take effect. If you do not fall asleep within that time frame, you are likely thinking too much. If that were the case, I would recommend taking 1 or 2 capsules of valerian (500 mg strength) from the health food store. This combined with melatonin should help in more than 80%-90% of insomnia cases.

Not sleeping through: Some of you, particularly if you are elderly, may wake up at 3 or 4 AM and have a hard time falling asleep again. At that time it would be safe to take another 3mg of melatonin and if this does not work within 20 minutes add another 500mg valerian capsule.

If you continue to have insomnia problems, see your physician. You may need sleep studies done or you may have problems with your thyroid gland (hypo- or hyperthyroidism), which needs to be checked. Other medical problems including depression have to be checked out as well. Melatonin and valerian are safe. Other sleeping pills have multiple side effects including memory problems.

Part of good sleeping habits is to provide a quiet, comfortable bedroom

The following points are good checklist for a comfortable sleep environment (Ref.1).

  • Ensure your bedroom is dark, soundproof, and comfortable with the room temperature being not too warm, and you develop a “sleep hygiene”. This means you get to sleep around the same time each night, have some down time 1 hour or so before going to bed and get up after your average time of sleep (for most people between 7 to 9 hours). Do not sleep in, but use an alarm clock to help you get into your sleep routine.
  • Avoid caffeine drinks, alcohol, nicotine and recreational drugs. If you must smoke, don’t smoke later than 7PM.
  • Get into a regular exercise program, either at home or at a gym.
  • Avoid a heavy meal late at night. A light snack including some warm milk would be OK.
  • Do not use your bedroom as an office, reading place or media center. This would condition you to be awake.  Reserve your bedroom use only for intimacy and sleeping.
  • If you wake up at night and you are wide awake, leave the bedroom and sit in the living room doing something until you feel tired and then return to bed.
  • A self-hypnosis recording is a useful adjunct to a sleep routine. Listen to it when you go to bed to give you something to focus on (low volume) and you will find it easier to stop thinking.

Conclusion

We need to be aware how important a proper hormone balance is when it comes to a healthy sleep pattern. Thyroid hormones and sex hormones are easy to measure. Bioidentical hormone replacement is needed, if one of the hormones is low. GH needs to be checked by an IGF-1 level and/or metabolites of GH in a 24-hour urine sample as explained above. Melatonin deficiency in older age is replaced the way I summarized above. With these measures sleeping habits improve, and you will get your 7 to 8 hours of restoring sleep. Forget the notion of the past that older people would not need as much sleep. Especially for an aging individual it is important to have a good night’s sleep in order to feel well and energized every day.

Effects Of Hormones On The Heart

Since February is heart month, I believe that this is a timely topic to understand how we can protect ourselves from heart disease. During the 23rd Annual World Congress on Anti-Aging Medicine on Dec. 11-13, 2015 in Las Vegas Dr. Ron Rothenberg gave a talk entitled ”Hormones And The Heart”. He stated that he wanted to give an overview of the effects on the endocrine system and on the cardiovascular system, in particular the effect of testosterone and estrogen. Also discussed were the effects of thyroid hormones, growth hormone, vitamin D and melatonin. In the following I will summarize what he explained in detail.

Testosterone treatment in men

He stated that there has been some confusion about the protective effect of testosterone on the heart in men. But Dr. Sharma and colleagues who investigated 83,010 male veterans with documented low testosterone levels clarified this confusion with this large study.

One group was given testosterone replacement therapy, another was not given replacement therapy and one group was given replacement with testosterone, but normalization of testosterone levels was not achieved.

The various groups were followed for between 4.6 years and 6.2 years. The results were astounding: When results between testosterone treated men were compared to non-treated men there was a 56% reduction of all cause mortality, a reduction of heart attacks by 24% and a reduction of strokes by 36%. There was no difference between the non-treated control group and the partially treated testosterone group where the testosterone levels did not come up. It is clear from this that with proper testosterone replacement where testosterone levels are monitored and corrected, significant reductions in strokes and heart attacks can be achieved. The explanation for these findings is simple: both, brain cells and heart cells in males, have testosterone hormone receptors that need to be stimulated for full function.

Hormone replacement in women

This topic has been clouded for many years because of the insistence of the medical profession to use horse derived estrogen (Premarin) and synthetic Provera (instead of bioidentical progesterone). These artificial hormone-like substances were used in the much-discussed Women’s Health Initiative (WHI).

Dr. Rothenberg said about this study that investigators used the wrong estrogen, the wrong progesterone, the wrong route of administration of estrogen (oral estrogen causes inflammation), and the wrong women at age 63 who already had cardiovascular disease and breast cancer.

One important aspect that was learnt by re-interpreting the WHI was that when estrogen replacement was initiated right away when menopause started, the heart attack risk went down by 34%. Estrogen and Provera together reduced the risk only by 28% (Provera being the wrong hormone). Again, the explanation for this findings is simple: women have both estrogen and progesterone receptors in heart and brain cells, which want to be stimulated with the natural hormones. When estrogen is missing, women need bioidentical replacement of what is missing with estradiol transdermal creams. When progesterone is missing, replacement with bioidentical progesterone transdermal cream or with micronized progesterone orally is needed.

Estrogen

With regard to estrogen replacement the KEEPS study has shed a new light on what is going on with hormone replacement in women.

This study was done on 700 women in early menopause. They were treated with 0.45 mg of Premarin (still the wrong hormone) or 50 micrograms of transdermal estradiol (the right active human estrogen). Women also received 200 mg of micronized progesterone (Prometrium, the real human progesterone) for 12 days each month. After 4 years of observation there was no case of breast cancer, uterine cancer, heart attack, transient ischemic attack, stroke, or blood clots in veins between the three groups. Both Premarin and transdermal estrogen had slightly reduced coronary artery calcifications on CT scans compared to the placebo group without hormones. The Premarin group increased the triglyceride and the CRP (a measure of inflammation) levels while the transdermal human estrogen did not do that.

Another study showed that due to the WHI study with the wrong synthetic hormones many women were fearful of starting estrogen replacement. The lack of hormone replacement with nature-identical hormones is responsible for the death of many women, who did not have the beneficial effects. They died of cancer and heart disease.

Dr. Rothenberg explained that this study and others have shown the following:

  1. Bioidentical hormone replacement must be started immediately at or before menopause to have the best results in terms of cardiovascular and neuroprotective (Alzheimer’s) prevention.
  2. Oral estrogen induces inflammation, which causes heart attacks, strokes and venous thromboembolism (blood clots). To prevent this, estradiol must be given as a transdermal cream. This will avoid the first pass effect through the liver, which is the cause for inflammation. Transdermal estradiol does not have the first pass effect. Inflammatory cytokines are implicated in autoimmune processes, initiation of cardiovascular disease, osteoporosis and Alzheimer’s disease.
  3. If estrogen replacement is not done right away with the start of menopause, the estrogen receptor may get damaged, which means that when estrogen replacement is started at a later date, it is no longer effective.

Progesterone

Progesterone is the other female hormone that is often overlooked. It balances the effects of estrogens, but it can also be metabolized into estrogen or testosterone. Tiny amounts of testosterone are necessary for normal libido. Progesterone production from the ovaries is already reduced when the woman is premenopausal and should be replaced by transdermal bioidentical progesterone cream.

Estrogen dominance needs to be treated with transdermal progesterone (or micronized oral progesterone). Both estrogen and progesterone can be accurately determined using a saliva hormone test. Blood tests are accurate for estrogen levels, but not for progesterone levels.

Thyroid replacement

Not infrequently thyroid tests are low (hypothyroidism) and cholesterol levels rise. This can lead to heart attacks and strokes. For instance, a slightly elevated TSH of 5.5 is associated with a total cholesterol level of 209 mg/dL, and a TSH level of 7.0 is associated with a cholesterol level of 270 mg/dL (normal less than 180 mg/dL). It is very important to detect hypothyroidism early and to treat it effectively to prevent cardiovascular disease. The active thyroid hormone is T3. Thyroid replacement has a stabilizing effect on the heart rhythm. It works together with testosterone in men and estrogen in women to stabilize metabolism of all cells, but in particular the heart muscle cells and brain cells. Hypothyroid patients are often depressed, but thyroid replacement lifts the depression. Cognitive deficits in patients with hypothyroidism are also remedied with thyroid treatment.

Growth hormone replacement

Growth hormone (GH) is important in childhood for bone growth and growth of all the organs. But GH still has an important function later in life. GH improves cardiac performance; it does so by thickening the wall of the left heart chamber, the main pump of the heart muscle. GH improves the contractility of the heart muscle, reduces the stress on the heart muscle wall and decreases vascular resistance. In animal experiments it was found that GH plays an important role in remodeling the heart after a heart attack.

GH deficiency occurs with aging; it leads to high LDL (bad) cholesterol and high triglycerides in the blood and increased fibrinogen, which causes blood clots. All of this increases the risk for heart attacks and strokes.

When people age, they lose GH production, which puts them at a considerable risk to get heart attacks and strokes, but they are also at a higher risk of serious falls due to muscle weakness and balance problems. When the doctor detects low IGF-1 levels in the blood and confirms low GH metabolites in a 24-hour urine sample, the time has come to do daily GH injections with human GH. This can be done using a similar pen that is used for insulin injections. The dosage is only between 0.1 mg and 0.3 mg per day, given before bedtime. This is remarkably effective not only for heart attack and stroke prevention, but also to treat muscle weakness, lack of mental clarity and general well being. Patients report that their joint and muscle aches disappear and they can engage in physical activities again.

Melatonin replacement

Melatonin is a hormone that is mostly thought of as the “sleeping hormone”. It is released by the pineal gland and rules overnight giving you a refreshing sleep. In the morning and during the day the light that enters your eyes inactivates it.

Melatonin is a powerful antioxidant, stabilizes the heart’s rhythm (anti-arrhythmic activity), is anti-inflammatory, anti-hypertensive and protects against heart attacks and strokes. People who have heart disease are usually found to have very low blood melatonin levels. Melatonin can be used intravenously in patients who have heart attacks to reduce the amount of damage to the tissue and stabilize the heart rhythm.

Like with GH, the production of melatonin deteriorates significantly beyond the age of 40. Blood levels of melatonin can be easily ordered, and replacement is easy to do. 3 mg of melatonin taken at bedtime will be a sufficient dose for most people. Another 3 mg can be taken, if you wake up in the middle of the night. It will wear off within 3 to 4 hours.

Vitamin D replacement

The history of vitamin D3 is interesting. Vitamin D3, the active form of vitamin D has many actions: it stimulates the immune system and reduces the risk of infection, it reduces blood pressure, it reduces inflammation by reducing circulating cytokines, and it increases insulin sensitivity making insulin receptors more responsive.

Vitamin D3 binds to the vitamin D receptor, which is contained on all cells.

Many middfle-aged and older people are deficient for vitamin D.  A lack of it leads to higher mortality. Vitamin D helps to restore circulation in patients with ischemic heart disease. Vitamin D insufficiency causes high blood pressure, diabetes and metabolic syndrome, enlargement and thickening of the wall of your heart’s main pumping chamber, heart failure and chronic vascular inflammation.

A prospective 7.3-year study looked at the hazard ratios of the Third National Health and Nutrition Examination Survey (NHANES III) and linked mortality files with lower 25-hydroxyvitamin D levels. There were 33,994 persons part of the survey, of whom 1,493 died.

Below 10 ng/ml of 25-hydroxyvitamin D level the mortality was 2.5 fold for all causes and 3.08-fold for cardiovascular causes compared to those with levels of 100 ng/ml or higher.

The recommendation presently is to maintain serum levels at 60-80 ng/ml of 25-hydroxyvitamin D to prevent cardiovascular disease.

Effects Of Hormones On The Heart

Effects Of Hormones On The Heart

Conclusion

The following is important to remember regarding prevention of heart disease.

  1. Never smoke or if you do, quit smoking.
  2. Have your thyroid hormones checked as thyroid hormones are important as an energy source for your heart muscle, and they lower LDL cholesterol levels.
  3. Your sex hormones matter: in men it is testosterone, in women estrogen and progesterone that support your heart.
  4. Vitamin D is not only important when we grow bones as youngsters, but it continues to be important when we are older. It supports our heart and other body functions. It is an essential team player, as it prevents premature deaths. Blood levels of vitamin D are easy to measure.
  5. Two hormones leave us rapidly as we age: melatonin and human growth hormone. However, levels of both hormones can be measured and if low, they can be replaced.
  6. There are only two more things you need to do: eat a Mediterranean type diet and exercise on a regular basis. This will ensure your heart is still healthy in years to come.

How To Cope With Time Switches

In Europe daylight saving time begins on the last Sunday in March and wintertime starts on the last Sunday of October. Here in North America we start daylight saving time on the second Sunday of March and end it on the first Sunday of November each year.

Having gone through this exercise just last weekend I thought it would be worthwhile to comment in a blog how our bodies, particularly our hormones are affected by this.

You may have heard about the circadian rhythm with respect to hormones. The changes of the sun causing the day/night cycle have profound influences on our hormones, called the diurnal hormone changes or the circadian rhythm.

How do circadian rhythms work?

In the morning when you open your eyes, light enters our eyes and is registered in the hypothalamus (suprachiasmatic nuclei, see Ref.1). There are also links from the hypothalamus to the pineal gland, where melatonin is synthetized and stored. The light signal stops the secretion of melatonin from the pineal gland, although it is still being produced during the day in the pineal gland, but stored there until the evening hours set in. You may have noticed that you start yawning when the light dims in the evening. That’s when melatonin is released into your system to let you know its time to go to sleep.

Of course, we have electrical light and can turn night into day if we choose to! This works for a limited time, but eventually tiredness sets in, and melatonin wins the upper hand. Melatonin is the master hormone of the circadian rhythm.

It is interesting to note that cortisol does exactly the opposite. Cortisol is the adrenal gland hormone that helps us cope with stress. When we are fully awake, we need cortisol to cope with stress. Melatonin inhibits cortisol secretion and cortisol inhibits melatonin secretion, so they are natural opponents working together for your common good. This is part of the circadian rhythm. We can measure these hormones and this is how researchers have found out how this works.

How To Cope With Time Switches

How To Cope With Time Switches

Time switches affect the circadian rhythm

When we switched time back by one hour on our wristwatch and clocks, the internal time in our body did not accept that right away. The body needs to gradually adjust to this by reading the external signals: when are we opening our eyes? What is the light intensity when we get up, what is the light intensity when we go to sleep?  Some people find it easy to adjust; others find it very difficult to adjust. Some individuals breeze through the adjustment process in a day or two. For others it can as much as 1 or 2 weeks before the hormonal adjustment is completed.

Symptoms of problems adjusting the circadian rhythm

Symptoms due to time switch are a feeling of hangover on the first one to two days after the switch. This is despite you having gotten enough sleep, but the quality of sleep was not the same as before the time switch. Your head feels heavy, you are irritable, and you may feel mildly depressed. You also may find it more difficult to concentrate on one thing and you experience fatigue. Some experience insomnia. What is behind this is a disturbance of your cortisol levels. Your cortisol level is normally highest in the early morning hours, just before you wake up. As a male your testosterone level is also highest when you wake up thanks to the circadian rhythm. Both cortisol and testosterone have been built up during your deepest sleep. In women the ovarian hormones have not only a monthly rhythm, but also a 24 hour diurnal rhythm, based on the internal 24 hour clock. The hypothalamus and the pituitary gland are intimately involved in both sexes regarding this diurnal rhythm and are in communication with the pineal gland that produces melatonin to regulate all of the major hormone systems. So, when we switch our watch back by one hour in the fall or forward by one hour in the spring, our body clock is out of sync with the new time that rules the world. This state of being out of sync may last for a few days. We still get tired according to the old time and we still wake up according to the old time until our internal clock has readjusted. People have genetic differences on how quickly they readjust.

Newer research on how the body tells time is summarized here.

Jet lag

When we travel eastward or westward through time zones a phenomenon of being “out of sync” occurs as well, very similar to what happens with time switches. It is the same re-adjusting process of the internal circadian rhythm that our bodies have to come to terms with. Some people are affected more when they travel west though time zones, and it may take them longer to adjust to it compared to traveling east. But other people complain that for them it is just the opposite, and traveling east is the problem for them. North-south travel does not cause jet lag as the internal time and the external time remain synchronized. A very similar phenomenon is happening with the spring and fall time switches. Some people find it nervier when in spring the clock is advanced by one hour and others complain that fall is their difficult time when the time is switched back by one hour. There are genetic differences of how we adjust with our internal clocks.

Shift workers

Shift workers experience problems with the circadian rhythm as well. The switch between working day shifts and night shifts leads to a condition called “shift-work sleep disorder” (Ref.3). Similar to jet lag this is due to the fact that synchronization between the body’s inner clock and external cues are disrupted, and not enough time is allowed for recovery. It would be much more cost effective, if unions and employers allowed those who are naturally born to cope with night time shift to work those shifts and allow those who are sensitive to shift-work sleep disorder to work only day shifts. We live in an age of political correctness, but we tend to overlook how our bodies work.

What you can do to ease yourself into the time switch

1. As there is a lack of deep sleep with the time switch, it is not a bad idea to take a short nap when you feel tired during the day. Catch a nap on the weekend or on a day, when you are off work! It’s good for you! This will build up your adrenal gland hormones and give you the extra surge of energy you are craving for.

2. At the end of the day though, you need to go to bed according to the new time to train your pineal gland and your entire hormone system about the new time situation. Your body needs the cues from you, when you start and end your day, so that it can sync your internal clock with the outside time.

3. A simple remedy that fits right into your hormone rhythm is to take a melatonin tablet (about 3 mg for an adult), available at your health food store or drug store 30 minutes before bedtime. Ref. 2 states that melatonin “restores circadian rhythm“. This will help your circadian hormone rhythm by giving it an evening boost of melatonin telling your system it is time to go to sleep. At that time when you close your eyes the signals through the optic nerve are shut down, giving the circadian rhythm yet another signal about what time it is. In just a few days (for very sensitive people in 1 to 2 weeks) your entire hormone system including the circadian 24-hour undulations will be reset. Now your internal clock has been reset and is in sync until the next time switch.

Protect Yourself From Radioactivity

Even though the Chernobyl catastrophe was bad enough, it appears now the 2011 Fukushima Daiichi nuclear power plant catastrophe was 7 to 10 times worse in terms of worldwide radioactive pollution. Even as late as Feb. 20, 2014 there was a new report of further radioactive water spill into the Pacific Ocean.

It is important that you start thinking about preparing yourself to cope with radioactive pollution.

In this blog I will briefly review the history of several radiation disasters in various parts of the world and will mention how coping mechanisms with radiation were fortuitously developed. Finally, I will summarize what you can do to reduce any damage to your health that is caused by radiation leaks.

History of the first nuclear bombs with radioactive fallout in 1945

On Aug. 9, 1945 the second atomic bomb was dropped on Nagasaki, Japan. Dr. Akizuki  worked at the St. Francis Hospital (Uragami Daiichi Hospital), about one mile from the epicenter. He and a staff of 20 were serving at this hospital that looked after 70 tuberculosis patients.

Miraculously all of the staff and most of the patients survived because of a vegetarian diet, which consisted of uncontaminated brown rice, fermented foods, sea algae and vegetables. Dr. Akizuki did not allow sweets of any kind. Salt was allowed as the main condiment. Everybody was fed at least one helping of a soup with fermented soy and seaweed in it (wakame miso soup). Other investigators have confirmed that in a mouse model miso soup has radio protective effects.

The staff and the patients of another hospital also one mile form the epicenter were not so lucky. Almost 100% of them died. They were not on the strict miso/seaweed diet without sugar and sweets.

Protect Yourself From Radioactivity

Protect Yourself From Radioactivity

The experience with Chernobyl

Perhaps the best way to start reviewing the Chernobyl disaster of April 26,1986 is by looking at how children fared who had been directly exposed to the radiation spill from this disaster. As this link shows about 7 million people living in the nearby area were exposed to the highest radiation exposure ever since the atomic age. The children of this population have experienced a 2,400 % increase in thyroid cancers, a 100 % increase of cancers and leukemia and a 200% increase of breast cancer. There were about 800,000 men who risked their lives when working on containing the radiation spill. 25,000 of these men have died and 70,000 are disabled. 20% of the deaths (5000 men) were due to suicide. Here is a report for those who like more details about the health consequences as a result of the Chernobyl disaster. Here are more questions and answers regarding the Chernobyl disaster.

The question is whether a similar accident could happen with any of the other nuclear power reactors. This link explains that such an accident can “only happen in a reactor operating with a Positive Temperature Effect combined with a Positive Steam Effect, and built without a containment structure to mitigate the potential atmospheric effects of a worst-case reactor accident.” It goes on to say that only the reactor in Chernobyl was this type of a reactor, the RBMK series made by the former USSR. The link above goes on to say: “All other reactors for the production of electricity, including all those in America, operate on natural Negative Temperature and Negative Steam Effects, and are encased in air-tight multi-layered containments, the integrity of which rivals that of Egypt’s pyramids.” It ends with this rather strong statement: “This being understood, it is entirely correct to say that an accident like the one that occurred at Chernobyl in 1986, will never happen anywhere else.” The same website reports in another section about the Fukushima disaster, without mentioning that this should not have happened. Nobody could have predicted the forces of nature (a double whammy of an earth quake of the magnitude 9 on the Richter scale, followed by a horrendous tsunami), which destroyed part of the nuclear power plant. From the literature it is not clear whether the government went through any major efforts to provide chelating agents, Prussian Blue and iodine salts to the affected population either in Chernobyl or in Fukushima to minimize the radiation effects from the radioactive emissions.

Part of the problem in Chernobyl was at the time that this all happened behind the iron curtain and that there was a news blackout, which only gradually improved after 1989. In Japan the problem was severe denial and underreporting on behalf of the Japanese government.

Goiania accident involving radioactive cesium-137 in Brazil

On September 13, 1987 two fellows illegally entered an abandoned private radiation treatment hospital in Goiania where a radiation unit containing cesium-137 had been used for treating cancer patients. They stole the radiation head thinking that it might  be valuable scrap metal that they could sell. They managed to sell it to a junkyard owner, Devair Ferreira.

Having a lack of insight that the radiation head would contain radioactive cesium-137, which was emanating ionizing radiation, Devair proceeded to probe for a precious metal with a screwdriver. As the details in the Wikipedia link show, shortly after a total of 112,000 people were screened for potential radiation exposure. There were 4 deaths including the junkyard owner’s wife, and his 6-year old daughter. He himself survived the incident. 249 people were significantly contaminated with cesium-137 and 1000 people had received a dose twice the amount of the yearly background radiation. 20 patients developed radiation sickness and required treatment. As this link shows the Brazilian authorities arranged treatments for  patients who had proven contact with cesium-137 with 10 Grams of Prussian Blue daily, which reduced the effective radiation exposure by 70%. This was the reason for the relatively low mortality and disability rates from this serious accident.

The Fukushima experience

Fast-forward to the latest disaster that has made clear how an earthquake of the magnitude of 9 on the Richter scale followed by an enormous tsunami in combination could lead to the Fukushima disaster in Japan. Following the catastrophe on March 11, 2011 there have been several leaks of radioactive material into the ocean, which are described here.

Dr. John Apsley II also pointed out that with the explosions in Fukushima there were also significant releases of radioactive pollution into the stratosphere that subsequently traveled around the globe. He has made it his ambition to help people minimize radiation exposure from nuclear accidents such as Fukushima.

The initial denial of the Japanese authorities caused a problem of assessing the true significance of the Fukushima incident.

As mentioned in the introduction to this blog there are still ongoing releases of radioactive material, which will eventually work their way into the oceans and into the atmosphere. Dr. Apsley II describes in detail in his book that there were 29 radioactive elements that were released into the air and into water, the main ones being Cesium-137 (and 134) Iodine-131, Plutonium-238 and 239, Strontium-89 and 90 and Uranium-234 and 238. As the body takes up these radioactive elements, they have different organ preferences and they metabolize differently so that each of them causes a certain disease pattern. Radioactive Iodine for instance causes thyroid disease and thyroid cancer, while radioactive Plutonium is causing leukemia, heart disease, lung and breast cancer, several childhood cancers and infant mortality. There is a wave of radioactive cesium-137 coming across the Pacific Ocean that will start to show on the west coast of Alaska, Canada and the US mainland by 2015 and stay peaked until 2020 and beyond.

Ref. 1 points out that it is difficult to know the real concentration of the radioactivity in the water and in the radioactive rain over the US and Canada, as government agency measurements were kept hidden or were falsified. However the author comes to the conclusion in comparing various reference sources that the radiological leak and impact of the Fukushima crisis was and is about 7-fold to 10-fold bigger than that of Chernobyl.

Depending on what story you believe, the fear mongering or the more balanced reasoning arguing that there is enough water in the ocean to significantly dilute the amount of spilled radioactivity, you may or may not eat the sushi on the West coast.

With all this noise it is unclear whether the local population made use of the simple method of chelation at home using miso soup and uncontaminated seaweed. One would hope so. But did they know that it is only effective in combination with a strict diet without sugar and starchy foods?

Protection from radioactive fallout

This brings us to toxicity studies and simple ways of how to protect you from radiation in the environment. First, you need to know how radioactive materials can enter your body. Most nuclides (that is another name for radioactive compounds) enter the body through contaminated food via the gut where they are absorbed into your blood. You can inhale gases like gaseous radioactive Iodine or Radon. Cesium, which has now leaked into the Pacific Ocean can be absorbed through your skin when you walk on a beach that is contaminated with radioactive Cesium-137 containing ocean water. Cesium-137 has a half-life of 30 years meaning that after 30 years it still emits 50% of today’s gamma rays (these are strong X-rays). The biological half-life of Cesium-137 in the body is 110 days. But we do not want this stuff in our bodies causing free radicals to destroy our body cells. So we need effective methods to remove radionuclides.

By reviewing the history above, we already have learnt of two effective ways to remove such radionuclides: Miso soup with seaweed in Nagasaki; and Prussian Blue in Brazil. Prussian Blue works on eliminating the radioactive Cesium-137 before it is absorbed from the gut into the blood. It disappears from the body with bowel movements and also in the urine. However, it should only be taken, when there is proven food contamination with Cesium-137 as it can seriously affect your potassium levels, which could cause serious side effects to your heart. A physician knowledgeable in the use of Prussian Blue can monitor your potassium levels and follow you along.

In comparison to that it is easy to implement dietary habits as was done in Nagasaki:  miso soup and seaweed can be consumed without any side effects. So, why is it important to avoid sugar and starchy foods? The reason is that sugar oxidizes your cholesterol and any tissue it comes in contact with. It also causes the pancreas to overproduce insulin, which causes an inflammatory reaction. Cesium-137 also causes an extreme inflammation in your body, because of the free radicals that are caused from the gamma radiation of cells. Add to this a situation where there is a fire burning inside of your body (inflammation from sugar and starch consumption) and you have a recipe for disaster, comparing it to dumping gasoline into a fire. Inflammation is amplified ,and the radioactive Cesium-137 causes havoc in your system. You quench the fire when you do not eat sugar and starch and you give it an extra dousing by taking chelating agents (miso soup with seaweed), which removes the radioactive Cesium-137. The successful outcome of Dr. Akizuki’s treatments in his hospital in Nagasaki speaks volumes.

There are a number of other useful antioxidants like melatonin, vitamin C, and glutathione. Co-Q10 supports the mitochondria and protects cholesterol from being oxidized. But other substances are also useful. Cabbage contains isothiocyanates that will bind radionuclides before they are even absorbed from the gut. Edible clays, like calcium bentonite works similar to Prussian Blue, but it also supplies extra calcium for the body. For further details consult Ref. 1, which contains a lot more details.

Conclusion

The surprising twist for me when I researched this topic was the fact that what is good for your heart, what prevents Alzheimer’s disease and what helps you to live longer also helps you to cope with processing and eliminating radioactive pollutants. When we adopt a healthier lifestyle now, we are at the same time preparing ourselves for the worst nuclear pollution.

Melatonin More Than A Sleeping Aid

Melatonin has been available to the public in the US since 1992. It is usually used as a sleeping aid or for jet lag related sleeping problems. However, in the last decade much more data about melatonin has come out that has proven that melatonin is a major hormone. The pineal gland contains another brain hormone, serotonin, which is converted into melatonin within that gland. Melatonin is a key hormone that regulates the sleep/wake cycle. It works in concert with cortisol, which has the highest level in the morning while melatonin has its highest level in the evening and during the night. Melatonin also regulates the menstrual cycle and determines when women get into menopause.

Lately new information has come to the forefront showing that there are connections to Alzheimer’s disease, Parkinson’s disease, stroke size and recovery from strokes. Even traumatic brain injury can be minimized when enough melatonin is present. In addition melatonin is an important anti-oxidant.

Finally, there is evidence that melatonin helps to determine how well we age.

In the following I like to review some of the evidence for all of these claims.

1. Melatonin as a hormone

Melatonin levels were found to be very low in breast cancer and prostate cancer patients. It has been determined that the immune cells have melatonin hormone receptors and need melatonin for stimulation. Because of the immune stimulatory effect of melatonin, it is often given as a cancer adjuvant treatment to other cancer treating modalities. Ref. 1 describes that melatonin regulates the female hormones (LH, FSH), which then determine when a woman has her menstrual period and also when she eventually enters menopause. The pineal gland is the master gland for the diurnal hormone rhythms.

2. Melatonin levels decline with age

Melatonin levels in both men and women decline as we age. This figure shows that the highest melatonin levels are reached by the age of 10; by the age of 40 only 15% of the youthful levels remain while by the age of 55 only 5% or less of the original youthful levels are left. This explains why older people are more prone to infections (missing immune stimulation) and why the sleep pattern in older people is changed (shorter periods of sleep, less restful sleep). Ref. 1 points out that with insulin resistance (from diabetes or due to excessive sugar and starch consumption) cortisol levels are chronically elevated, which in turn inhibits melatonin production.

3. Melatonin protects from neurodegenerative diseases

A newer application of melatonin is as a preventative in the neurological field, particularly in the area of Alzheimer’s disease, Parkinson’s disease and the prevention of strokes. With respect to Alzheimer’s disease studies have shown that patients with Alzheimer’s have much lower melatonin blood levels when compared to age matched normal controls. In ischemic stroke patients it was found that stroke patients had much lower melatonin levels when compared to normal age-matched controls. Other studies have shown that pineal gland calcification was associated with low melatonin levels and a high risk for ischemic stroke. This risk was even higher when the patients had high blood pressure, diabetes and high cholesterol/triglycerides. When a stroke has occurred, it is important that the free radicals are removed as quickly as possible, which is where the antioxidant properties of melatonin fit into a rehabilitative program. The presence of melatonin enhances brain plasticity. However instead of using melatonin after a stroke, it is much better to use melatonin regularly before a possible stroke, as this gives a better chance reducing the size of the stroke. This in turn will lead to a faster and more complete recovery after a stroke.

Another important disease of the elderly is Parkinson’s disease. Melatonin helps to prevent oxidative damage to the dopamine producing cells in the basal ganglia thus preventing Parkinson’s disease. As with Alzheimer’s disease, there is a correlation of low melatonin levels and this neurodegenerative disease, which goes beyond the age-related reduction of melatonin levels. In experimental Parkinson’s disease models in mice melatonin was highly effective in preventing deterioration of Parkinson’s disease.

4. Melatonin may extend life

The combination of being a free radical scavenger, an immunostimulant and an integral key hormone allow melatonin to have beneficial effects in the aging process. When melatonin supplements are given, the stimulation of the immune system can cut down infection rates in the elderly, prevent and mitigate degenerative diseases of the brain (Alzheimer’s, Parkinson’s), re-establish sleep/waking rhythms and help reduce arthritis.

Conclusion

Melatonin is a widely used sleep aid. As it is practically absent in people beyond the age of 55, it makes sense to supplement with melatonin in that patient group. However, there are side effects particularly in people on blood thinners as coumadin competes with melatonin in getting eliminated through the cytochrome P450 liver enzyme system. This will result in longer bleeding times in patients on blood thinners who also take melatonin supplements. It is important that patients discuss this with their doctors. However, given all of the benefits described above, for the vast majority of the baby boomers melatonin supplementation would be very beneficial. Doses as a sleep aid vary between 1mg and 5mg at bedtime for most people. Cancer patients require higher doses (10 to 20 mg per day).

Impressions From The 21st Annual World Congress On Anti-Aging Medicine (A4M) In Las Vegas

Every year in mid December Vegas hosts the world A4M conference (from the American Academy Of Anti-Aging Medicine). This year’s conference was at the Venetian/Palazzo Resort in Las Vegas, NV from December 13th to 15th, 2013.

There were more than 3,500 attendees who participated in this yearly continuing medical education event in preventive and integrative medicine. Over 50 speakers reviewed various anti-aging topics including aesthetic medicine and stem cell topics. In addition there was a huge exhibition with over 300 exhibiting companies of health related products and books.

I attended this conference to see what is new in anti-aging medicine, which is the focus of my interest since my retirement in 2010.

Here are some highlights the way I saw it. As the topics were varied, I simply present a potpourri of snippets, all of which have some usefulness.

1. Opening remarks by Dr. Ronald Klatz and Dr. Robert Goldman

Dr. Klatz pointed out that the A4M has been very active over the years in lobbying for making supplements more available to the public. In 1995 the A4M was defending melatonin as a harmless sleep aid and the FDA agreed to allow it to be freely sold in health food stores. In 1996 DHEA followed this trend. Because of pressure of the A4M on the FDA Co-Q10, an important cardio protective supplement became available in health food stores in 1998. In 1999 the A4M stated in a public statement that newer research has confirmed that insulin is involved in obesity and diabetes and is an important aging substance. Those who continue to have high fasting insulin levels, will age faster than the average population. But those who lose weight, and exercise will reduce fasting insulin and will no longer age prematurely. The reason for this is that inflammation is the cause of high blood pressure and of cardiovascular disease like heart attacks and strokes. Reduce or eliminate fasting insulin and you eliminate the risk for heart attacks and strokes. In 2004 the A4M announced that stem cells could be used as an important tool to treat various end stage diseases to allow people to live longer. Since then this has become a huge specialty area. There was also a separate pre-conference workshop on stem cells. In 2009 the A4M announced that vitamin D3 was effective beyond bone health. Every cell in the body contains vitamin D receptors. Originally the 400IU per day RDA dose was established to fight rickets. Now it is recognized that 4000 or 5000 IU of vitamin D3 are required every day for a multitude of normal body functions. People with the poorest lifestyles have the shortest life expectancy, 66.5 years in Native Americans of South Dakota; in contrast the longest life expectancy in the US is found in Asian American women in New Jersey with 91.8 years. It just so happens that in New Jersey most of the 26,000 A4M physicians are practicing, which may be one of the reasons for the impressive longevity figures.  Dr. Katz suggested that we should recommend the following website to people: http://www.worldhealth.net/  This is the official medical news website of the A4M and deals with the latest health recommendations.

Dr. Goldman added to this that the anti-aging industry is growing rapidly (0$ in 1991; 250 billion $ in 2012; an estimated 345 billion $ in 2018).

He also emphasized that anti-aging can only be achieved, if blood tests are done early to detect any hormone or chemical abnormalities in the beginning stages before permanent organ damage sets in. Only with early detection can effective anti-aging treatments be initiated. Prevention is always better than waiting for an emergency to occur and then wanting to fix it, as it is commonly done in the conventional medical system.

2. Hypertension diagnosis and treatment

Dr. Mark Houston (Nashville, TN) talked about new and revolutionary concepts in treating and diagnosing hypertension (high blood pressure). Endothelial and vascular muscle dysfunction are now in the center of the researchers’ attention. The reason for blood pressure to get elevated is from a combination of inflammation, oxidative stress and autoimmune dysfunction of the vascular system. Decades before the blood pressure shoots up, there are vascular and heart abnormalities. 24 hour ambulatory blood pressure monitoring (24hour ABM) is the most reliable test for assessing blood pressure.

Among other things a micronutrient test was suggested as this way a lack of magnesium could be detected. Too little magnesium in the blood has to be treated with magnesium citrate supplements.

In terms of treatment it was interesting to note that diuretics and beta-blockers are no longer recommended, because of serious side effects. Instead of these medications the treatment of choice now are calcium channel blockers (Diltiazem etc.) and angiotensin II receptor blockers (Losartan etc.):

3.  Testosterone therapy in men

This was the topic of Dr. Abraham Morgentaler, a professor of urology at Harvard Medical School. He asked whether it is a panacea, a scourge or the next big thing in medicine. He went through various literature citations that showed that there is no relationship between testosterone or DHT (de-hydro-testosterone) and prostate cancer. In a New England Journal of Medicine publication Dr. Morgentaler has shown by doing extensive prostate biopsies on men with or without prostate cancer that testosterone treatment did not cause prostate cancer or make prostate cancer worse. He found that testosterone treatment invariably made men feel better, and they had more energy using testosterone. They also lived longer. He also debunked a recent JAMA publication from November 2013 that stated testosterone replacement would have led to increased heart attacks. He explained that he called the editor after calculating the raw data and coming to the conclusion that the authors had miscalculated and misrepresented the data, as the risks of heart attacks in men using testosterone were actually half of what the controls without testosterone replacement showed. However, the editor elected to keep the false data in the publication, which has caused confusion with the public and with the medical profession. Here is another rebuttal by Dr. Trutt who came to the same conclusion. Fact is and this is in agreement with many other medical publications in the US, Europe and around the world that testosterone replacement (with bioidentical testosterone) in a testosterone deficient man will cut the risk for heart attacks and strokes into half of what it would be if he did not replace with testosterone. However, only bioidentical testosterone will show this heart and brain saving effect, as there is a key/lock mechanism between bioidentical testosterone and the testosterone receptors of heart and brain cells and the testosterone receptors in the arterial walls.

4. Keynote speaker

Suzanne Somers was the keynote speaker on the first day of the conference in a talk entitled “Our time has come”. Her books have greatly contributed to the popularity of the anti-aging movement in North America and around the world. She described how important it was for her to take charge of the health care in her own case and to explore alternatives to treat her breast cancer in the past. She allowed a lumpectomy, but she refused chemotherapy which conventional medicine wanted to force on her. Instead she changed her lifestyle completely as summarized in her books, particularly in “Breakthrough”. She also became one of the pioneers in the US to get the newly FDA approved mesenchymal stem cell/fat cell transplant done on the affected breast to restore the pre-surgical appearance. She made a plea to those who can afford it to bank their stem cells, which was later reiterated by Dr. Terry Grossman, MD whose lecture I did not review here. I noted this key sentence in Suzanne Somers’ speech towards the end: “I work prophylactically to take care of my health”. How often have I wished in the past that every one of my patients would have this attitude!

5. Hormone testing and nutrition

Jim LaValle, an adjunct professor in the College of Pharmacy, University of Cincinnati has more than 27 years of clinical experience in the field of natural therapeutics and functional medicine. He mentioned that many people are toxic from a leaky gut due to faulty nutrition, which in turn will lead to heart disease and kidney disease. Once a patient has heart failure, a leaky gut will make the heart failure worse. Leaky gut leads to multiple autoantibodies, which causes various autoimmune diseases. Another area he concentrated on in his talk is the fact that neuroplasticity in the brain can restore people’s brain after brain injuries or when autoimmune diseases have attacked the brain. Through lifestyle changes stem cells in the support tissue of the brain, called glia cells, can develop into neural progenitor cells, immature newborn granulocyte cells and eventually into mature nerve cells. In other words the same sequence that occurs in the embryo with brain maturation can also occur in adults. Researchers are only learning now how to approach this difficult subject. He pointed out that there has to be a balance between the gut, the brain and the immune system. As the gut is also an immune organ (Peyer’s patches) where Th1, Th2 and Th17 lymphocytes are produced, it is important to manage your gut through probiotics and through intake of organic foods to get away from anything that disbalances the gut/immune system/brain interaction. At the end he briefly touched on two important facts: zinc is a trace element that is important for prevention of a leaky gut as it keeps the cell bridges of the lining of the gut intact. However, when zinc levels are done on patients in the hospital setting, he found that patients are often deficient for zinc, but they are responding very rapidly to zinc supplementation. Stress, which causes high cortisol levels leads to lowered endurance, autoantibodies and allergies. By checking other hormones, which need to be in balance with cortisol the caregiver can recognize what is wrong with a patient and help restore the hormone balance with bioidentical hormones. This will also take care of the leaky gut, the autoimmune diseases and improve asthma in a person who has allergies.

6. Aging and the short telomere connection

William Andrews, PhD has worked in the biotech industry for 28 years and had obtained his Ph.D. in Molecular and Population Genetics at the University of Georgia in 1981. In the last 15 years he has focused on finding ways to extend the human lifespan by interfering with telomere shortening in human cells. He shared some interesting facts with the audience: reproductive cells do not age and their telomeres stay long. He said that in order to age gracefully it helps to know the length of your body’s telomeres. He recommended using the HT Q-Fish telomere test, which is a genetic test that gives an average of the telomere status of your body. This test will determine the %-age of short telomeres in the body, which is what is most informative about your biological age and your average life expectancy. There are several methods that are useful to know, which lengthen your telomeres: exercise, omega-3 fatty acid supplements, vitamin D3 in higher doses and not smoking are all known to lengthen your telomeres. Astragalus, a Chinese herb and extracts (expensive!) derived from this plant have also been shown to increase the length of telomeres. Other factors that help to preserve the length of your telomeres are reducing stress (yoga, meditation, enjoyable music), weight loss through a ketogenic diet, reduction of depression (rebalancing brain hormones), reducing pessimism, and being happy. Did you know that lobsters are blessed with ubiquitous telomerase expression? As a result they turn over 100 years. Humans are not so lucky, but we have access to simple steps that are protecting our telomeres! Dr. Andrews’ company has searched for telomere elongating substances. Through testing of 39 families of chemicals that are stimulating telomerase to elongate telomeres, he found a few that work. However, the main first step should be to concentrate on restoring the diet of our distant ancestors that gave us our genetic make-up. He stated that the Western diet is the worst contributing factor for telomere shortening. The macro and micronutrient difference between our ancestral diet and the modern diets have caused diseases like high blood pressure, heart attacks, stokes, obesity, diabetes, insulin resistance, dementia and cancer. Our modern diets (particularly the high carb/low fat diets) have increased oxidative stress in our bodies from increased reactive oxygen. This reduces our antioxidant reserves. It leads to malfunctioning of the endothelial lining. Other contributory factors are the overfeeding with omega-6 fatty acids from processed foods and cooking oils(such as corn oil and soybean oil and others.). These food infractions lead to a relative lack of the key vitamins A, D, E and K2 that are important to maintain cell function.

7. Telomeres, Aging and Disease

This title was the talk by Dr. Mark Rosenberg, who has been involved with drug research since 1991. This lecture reinforced what Dr. Andrews has said. However, he added a few aspects that are important to mention: “aging promotes aging”; in an aging person there are more circulating free radicals that undermine your health. So it is important, particularly for an older person to take anti-oxidant supplements to stop free radicals from aging you even faster. Dr. Rosenberg has done a lot of research with cancer cells. He noted that the circulation in a cancer or in metastases from cancer is very poor, which is the reason why chemotherapy often does not reach the cancer cells. He also found in the literature and in his own clinical experience that patients with low LDL cholesterol have increased cancer susceptibility. He mentioned that this was a new paradigm. I have recently discussed this in detail in a previous blog. Briefly, LDL cholesterol is the transport form of cholesterol going from the liver to vital organs like the heart or brain. When LDL is oxidized by free radicals from eating too much sugar and starchy foods that are metabolized into sugar, cells are starved of nutrients and oxygen. This sets the stage for cancer cells to develop, which have a metabolic advantage of being able to produce energy by glycolysis rather than by the aerobic metabolic pathway. Smoking and alcohol consumption shorten telomeres and this makes the person more prone to developing cancer.  On the other hand telomerase treatments have been shown to NOT cause cancer, which was a false belief in the past. At this point it is lifestyle changes that are needed to reduce the using up (aging) of telomeres. Resveratrol, vitamin D3, and astragalus all seem to contribute to lengthening of telomeres. The next few years will likely bring more news about this.

Conclusion

I have only been able to give a few highlights of the 21st Anti-aging Congress in Las Vegas. Another highlight was an appearance of Travis Stork, MD from the ER-doctor show on television. He gave a very down-to-earth presentation making 4 points: 1) healthy living starts in the kitchen, 2) “I need you to start working out”, 3) Mind and body are connected (stress can ruin your health) and 4) Get enough sleep (40% do not get enough sleep), because all of your hormone glands are recovering overnight. He concluded by saying: “Make health your hobby!” Another happening later in the conference was the appearance of California’s 38th Governor, Arnold Schwarzenegger. He received the highest honor of the A4M, the 2013 INFINITI AWARD for his leadership role of funding and supporting stem cell research in California.

Each A4M conference seems to have something new to offer every year. There were many other things that I learnt, but in my mind the topics I summarized above stood out from the rest.

3. telomere lengthening by vitamins, minerals and supplements: http://nethealthbook.com/health-nutrition-and-fitness/nutrition/vitamins-minerals-supplements/   In this review I am mentioning a large Chinese study that proved telomere  lengthening with vitamin C and E, but no other vitamins. Other vitamins are still needed as antioxidants to prevent cancer and hardening of arteries.
