Smog From City Roads Reduces Your Life Expectancy 2-Fold

Our ancestors already knew the benefits of fresh air and the fact that your grandmother likely knew: country living is healthier than city living. Let me qualify this somewhat: A recent study from the Netherlands showed that smog in cities has a detrimental effect on a person’s health (based on Lancet 2002;360:p.1203-1209). Dr. Gerard Hoek and his team from the Utrecht University revisited a group of about 5000 patients 15 years after the completion of a lung cancer study that was done in 1986 on these patients.

The authors looked up the addresses and classified two groups based on where these patients lived in 1986, either beside a busy congested road in the city or in a rural country area. 11% of the patient population had died of lung or heart disease during this period of time. When all of the other factors were kept constant and only the area where they lived was different, these authors found a significant 2-fold difference, which was attributed to chronic exposure to air pollution from traffic. The main reasons for this difference, they stated, was due to chronic exposure to black smoke and nitrogen dioxide from the exhaust fumes of cars. This study showed that air pollution by itself can double the death rate over a longer time period such as 15 years. In other words: It matters what you breathe!

More Exercise Leads To More Health

Based on an article in the Journal of the American Medical Association (JAMA 2002;288:p.1994-2000) Dr. Mihaela Tanasescu and his group from Loma Linda University in California have followed more than 44,000 health care professionals every 2 years for 12 years.

He asked the question whether a difference could be found between light, moderate or heavy exercise in the prevention of heart attacks.

Here is what they found: 1700 new cases of heart attacks as a result from hardening of arteries were mostly found in those who did NOT exercise or were in the LIGHT aerobic category. The more the persons exercised, the more pronounced the heart protective effect was. For instance, the group of men who engaged in a heavy exercise program had developed 17% less heart disease than the group with the light exercise program. Contrary to the marathon runner studies that had reported a detrimental effect at the high end, this study did not find this effect.

Also, this study is one of the first to show that weight training and other muscle strengthening activities also reduced strokes and heart attacks. Up to now the medical community was of the opinion that body building type muscle training might not prevent strokes or heart attacks.

The authors concluded that a combination of aerobic exercises(brisk walking, running, sports etc.) with muscle strengthening exercises(body building, stretching exercises, weight lifting etc.) will give the most beneficial heart protecting health effect.
