Sun Exposure Helps Many Symptoms

For the past few years it has become evident that sun exposure helps many symptoms. Patients with psoriasis have skin plaques on their skin. With sun exposure some of them disappear and the skin appearance improves. Patients with seasonal affective disorder have worsening of their depression over winter. Depression lifts with more sun exposure in the spring. Even a complicated disease like MS, which is more common in the northern latitudes, improves with sun exposure or a move to the southern states.

Osteoporosis: sun exposure has a positive effect

Osteoporosis was the subject of an April 2016 study from Argentina.

The researchers counted the amount of actinic keratosis lesions on the skin of subjects. This correlated well with lifetime sun exposure. Next they measured the  occurrence of hip fractures from osteoporosis. There was a correlation of the two. This case control study had 51 patients with hip fractures. Controls were 59 patients from the same hospital without hip fractures. The mean age was 80 years of age. 23.5% of patients with a history of hip fractures were observed to have actinic keratoses. In contrast 40.7 % of actinic keratoses were found in controls.

Sun exposure prevents hip fractures

The authors conclude that higher sun exposure is protective of hip fractures, but led to more actinic keratoses. They also stated that higher actinic keratoses rates, which are precancerous skin lesions are a risk for developing skin cancer. It is important to balance risk of osteoporosis from a lack of sun exposure with the risk of skin cancer from overexposure to the sun.

We know that higher doses of vitamin D3 in combination with vitamin K2 and calcium supplementation prevent osteoporosis. Reasonable daily doses are 5,000 to 10,000 IU of vitamin D3 per day, 200 micrograms of vitamin K2 per day and 500mg of calcium daily.

Psoriasis: sun exposure helps many symptoms

Psoriasis is an inflammatory condition of the skin with plaques and a characteristic skin rash. This February 2016 study from Turkey showed significant differences between women with psoriasis versus controls. Bone density studies showed lower levels in psoriatic females than in female controls. Female psoriasis patients had lower vitamin D levels than female controls. Male psoriatic patients showed no difference from controls. Low levels of vitamin D3 may be triggers for osteoporosis to develop in female psoriasis patients. Inflammation may also be a contributory factor. There was an elevation of the C-reactive protein (CRP) in female psoriasis patients.

Clinical observations have shown for years that the rash of psoriasis patients tends to improve during the summer.

Seasonal affective disorder: sun exposure lifts the mood

Seasonal affective disorder (SAD) has been known to respond to light therapy. Typically it peaks in the winter months and presents in mostly females who live far away from the equator. They improve when they travel to a sunny spot such as the subtropics or the southern states of North America during the winter months. But light therapy, vitamin D3, antidepressant therapy and counseling the mood swings of seasonal affective disorder will lessen.

In this 2014 study it was shown that depression in older people was not related to the darker months (between October and March). The summer depression rates in older people were identical to the winter depression rates.

Clinical trials with seasonal affective disorder (SAD) patients

In a group of 38 patients with SAD 14 patients were treated with white light visors, 15 with infrared visors and 9 served as a control (visors, no light). Both white light and infrared treated groups showed prevention of SAD while the control group developed SAD.

A 6-week trial was published March 2015. It involved 78 patients (51 Afro-Americans and 27 Caucasians). They all had SAD and received a treatment with 10,000-lux bright light for 60 min daily in the morning. Caucasians had a response rate of 75%. African-Americans had a response rate of only 46.3%. The investigators found that the symptomatic improvement and the rate of treatment response were the same in both groups. The researchers found that the Afro-American subgroup of patients required more education resources. This can overcome the inconsistent application with the bright light.

Vitamin D trials regarding SAD patients

In a study involving 185 female undergraduates of the Pacific Northwest, vitamin D blood levels were measured and a correlation of low vitamin D with depressive symptoms was found in SAD patients.

In a small study the hypothesis was tested that vitamin D3 in higher doses would be beneficial for SAD patients. Eight subjects received a treatment with 100,000 I.U. of vitamin D3, while seven subjects received phototherapy. All subjects had their vitamin D blood levels checked. Interestingly the vitamin D3 group improved on all depression scales. The phototherapy did not show improvement on the depression scale. The vitamin D level increased 74% in the vitamin D3 group and 36% in the phototherapy group.

Light exposure and vitamin D supplementation for SAD

All of these studies seem to indicate that SAD is more common in a younger population while in older people depression seems to be year-round. SAD does respond very well to 1-hour exposure of 10,000 lux of light in the morning. On a sunny day a walk in the sun for 1 hour is equivalent to an exposure at home with a SAD light. High dose vitamin D3 supplementation makes sense as low vitamin D levels were a persistent finding among SAD depression patients.

Multiple sclerosis: sun exposure makes a difference

Multiple sclerosis (MS) is more common in northern latitudes of the northern hemisphere. It is thought that sun exposure leads to higher vitamin D3 production in the skin, which prevents MS. On the other hand, once the diagnosis of MS is certain sun exposure or high doses of vitamin D3 can make it better.

This 2015 Australian study showed the same findings with a large group of MS patients.

This 2015 study from Sweden indicates that there is a compelling connection of prevention of MS through sun exposure or the taking of supplements of vitamin D3. In view of this evidence the authors suggest that you should take vitamin D3 supplements for prevention of MS before trials confirm this further.

Sun protection needed to prevent skin cancer

We have been hearing the slogan “slip, slop and slap” for skin cancer prevention. Slip, slop and slap stands for: slip on a shirt; slop on the sunscreen and slap on a hat. This publication dated March 2016 questions whether the precautions have been too zealous.

On the other hand the statistics regarding higher precancerous actinic keratoses in patients without osteoporosis are alarming too. It seems better to use high doses of vitamin D3, which will prevent osteoporosis, depression (SAD), MS and also improve psoriasis. Sun protection has decreased skin cancer, but did not curtail melanoma rates because sunscreen lotion can be penetrated by infrared radiation.

Use common sense for skin cancer prevention

This means that you should listen to the advice to stay out of the intense sun between 11AM and 3PM. Use vitamin D3 supplements in higher doses as this protects your skin. Research from England indicates that melanoma patients are usually the ones that are susceptible to melanoma genetically. They also have low vitamin D levels in the blood to a certain degree from skin cancer formation. The researchers recommend strongly that those at risk for melanoma need to be on higher vitamin D3 supplementations. A patient with a diagnosis of melanoma should receive high doses of vitamin D3.

Sun Exposure Helps Many Symptoms

Conclusion

It is not a myth: sun exposure helps many symptoms as explained above. Diverse body systems like osteoporotic bones, psoriatic skin and seasonal affective disorder respond to sun exposure. Sun exposure also prevents MS, a degenerative central nervous system disorder. The effects of vitamin D3 can explain some of this effect. It likely stems from sun exposure to the skin. But sunlight has hormonal effects. This occurs through the optic pathways and connections to the hypothalamus. We know that the sun helps combat many symptoms, but more research will be necessary, till we know exactly how it works.

Sunburn Prevention

Much has been written about sunburn prevention. The thinking behind this is that perhaps we could prevent skin cancer and melanoma development, if we would block ultraviolet rays from the sun or from tanning booths irritate our skin.

So far the theory. Now the truth.

1. Increase of skin cancer despite sunscreen applications

It is sobering that statistics of skin cancer frequency  show that despite more awareness of the importance of skin protection with sunscreen lotions and creams, skin cancer rates have steadily increased. Behind this paradox is the fact that vitamin D3 production in the skin is blocked from sun exposure and the person is not getting the cancer protecting effect of vitamin D3.

Low vitamin D3 levels (measured as 25-hydroxy vitamin D3) are not only associated with skin cancer, but also with breast cancer, and breast cancer will be reduced to 50% of control groups, if patients are treated with high vitamin D3 supplements. There are many other cancers that respond to exposure to sunlight or to supplementation with vitamin D3.

2. We need to know about infrared rays and the ultraviolet exposure

The ultraviolet radiation of sunlight has been extensively studied. There are UVA rays that range from 315 to 400 nanometers. They make up about 95% of the sunlight and penetrate deeper into the skin (the dermis level) leading to more severe skin damage, producing aged looking skin.  UVB rays (5% of sunlight) contain wavelength measuring between 280 and 325 nanometers affecting the most superficial layer of the skin, the epidermis. These rays cause sunburns. Both UVA and UVB are strongest around midday. The sun also produces UVC rays (wave length 180 to 280 nanometers), which are completely absorbed by the ozone layer and are not of importance unless you live under an ozone hole.

Next there is IR (infrared radiation), which has only recently been detected to be of health concern. IR rays range from 760 nanometers to 1 million nanometers (=1 millimeter). It causes skin photoaging and damage. Most of IR is in the lower range (between 760 and 1,440 nanometers); the total amount of IR rays that reach the skin is massive compared to the UV light and 50% of these rays reach deep into the skin to the level of the dermis.

3. Filtering out the damaging rays

Armed with the above knowledge we can now talk about sunscreen lotions and sunscreen creams. Traditional sunscreen lotions and creams have been directed against both shortwave (UVB) and longwave (UVA) rays of the sun. UVB blockers prevent damage to the surface of the skin (epidermis level), UVA blockers prevent damage to the deeper dermis. It is in your interest to buy a sun blocking agent that blocks both of these rays. (You have to read labels.)

However, both of these blockers, which means all of the traditional sunscreen agents, will not block IR waves (infrared radiation), which causes most of the wrinkles, age-related skin changes and skin DNA damage, which eventually results in skin cancer.

4. Vitamin D3 deficiency because of sunscreen applications

As we know that sunscreen agents lead to blocking of vitamin D synthesis in the skin, it is prudent to take vitamin D3 5,000 to 10,000 IU per day and have your health care provider order 25-hydroxy vitamin D3 blood levels from time to time (aim for a level of 100 ng/m or more). There is no danger of overdosing vitamin D3. That story about overdosing of vitamins is coming from vitamin A overdosing. There is a ceiling not to be exceeded due to liver toxicity over vitamin A overdosing, but not so for vitamin D3. Vitamin D3 protects not only from skin cancer, but also from other cancers. For more on vitamin D3 read my recent blog on this.

5. Whole body protection from the inside

There are two approaches to using systemic natural extracts. One component is from a tropical fern (Polypodium leucotomos) and another one from blood oranges that can both repair sun damaged skin and prevent sunburn. The effective substances are administered orally.

This fern extract has been tested in smaller clinical trials and was found to have a 70% to 75% efficacy in blocking all sun rays from the inside out.

In a small trial patients were exposed to UVB light after preparation with red orange extract and a 35% reduction of sun burn was found within 15 days when compared to controls.

There is a possibility now to take one capsule with tropical fern extract mixed with red orange extract and combine this with traditional sunscreen agents and have optimal sun protection.

One trial that is mentioned in these last two links is a group of polymorphous light eruption patients who are born with extreme sun sensitivity, but reported an 80% improvement with this oral fern extract treatment.

6. Final recommendations for sunburn prevention

Although the advice given in this WebMD link is useful, it neglects to recommend to supplement with vitamin D3 because of the sunscreen action. It also does not mention the IR waves of the sun that do most of the damage and that only get prevented by staying out of the sun or by taking the oral sunscreen pill (tropical fern extract and red orange extract mixed).

My recommendation, if you were not allergic to ferns, is to consider taking the oral pill (as far as I know currently only available from LifeExtension as “enhanced fern block with red orange complex”) to block the entire wavelength of the sun rays. This will repair some of the skin damage that has already been done. Follow the above WebMD link as well with regard to the sun screen lotions/creams. Also stay out of the noon sun between 11 AM and 2 PM. Take your vitamin D3 in the high dose range as discussed above to preserve optimal resistance against all kinds of cancers including skin cancer.

Conclusion:

In reviewing the facts prior to writing this blog I was quite bewildered how misleading a lot of the literature is regarding prevention of sunburns, particularly by assuming that all you had to do was to block UVB and UVA rays. I attempted to explain why this is an oversimplification, and the skin cancer statistics clearly show that sunscreen blockers alone are not stopping skin cancer. So, we do need a combination of
1. Staying out of the noon sun.

2. Using clothing and wide sun hats to keep the sun out of our faces.

3. Use the traditional sunscreen agents. Reapply, if necessary.

4. Using an oral sunscreen agent that blocks infrared rays as discussed under point 5 and 6.

5. Using vitamin D3 in high doses as discussed under point 4 above for cancer prevention.

With this in mind, enjoy the rest of your summer!

No Relationship Between Allergies And Cancer

Two opposite opinions have been voiced. There is the sinister threat that people who are prone to allergies are also at risk for coming down with cancer, because their immune system is constantly in overdrive. The opposite rumoring has also been heard: people with an overactive immune system and allergies have a built-in protection against cancer, because their immune system is in a constant state of vigilance.
Researchers from the Karolinska Hospital and Institute in Sweden made a point to examine these opposed hypotheses in a study that involved 70,136 patients between the years 1988 and 2000.

All these patients were tested for allergic disease and the results were linked with data from the Swedish Cancer Registry. The total number of cancers found was what could be expected in the general population. In addition this large epidemiological study performed specific analysis for cancer of the lung, the cervix cancer, cancer of the pancreas as well as lymphoma and skin cancers. The findings demonstrated that none of these cancers were independently related to allergies.

Dr. B. Lindelöf and his research team concluded: “Our study did not support the reported decreased risk of cancer in allergic patients, nor did it support an increased risk.”
