Avoiding Sun May Be as Dangerous as Smoking

Swedish researchers studied 30,000 women over 20 and found the nonsmokers who stayed out of the sun had a life expectancy similar to smokers with the highest sun exposure. The authors suggest that overexposure should be avoided, but underexposure may be more dangerous than people think. Exercise and lifestyle data were not considered and might have confounded these findings.

PositiveTip: Vitamin D is essential for good health, and appropriate sun exposure is an excellent way of getting it.
