(18-08-08) Sunlight Can Cut Your Risk of Death in Half

Having low vitamin D levels has been linked with deaths from heart disease and other causes, adding to growing evidence about the "sunshine" vitamin's role in good health.

People with the lowest blood levels of vitamin D were about two times more likely to die from any cause during an eight-year period than those with the highest levels. The link with heart-related deaths was particularly strong in those with low vitamin D levels.

The study involved over 3,000 men and women in southwest Germany. Participants were aged 62 on average, and their vitamin D levels were checked in weekly blood tests.

It’s estimated that at least 50 percent of older adults worldwide have low vitamin D levels, and a significant number of younger people may also be affected. Low vitamin D levels may result from spending less time outdoors, air pollution and a decline in your skin’s ability to produce vitamin D from the sun as you age, the researchers said.
