The new study states spent an average of three hours a day exposed to sunlight may reduce the risk of breast cancer by 50 percent.
The study was published in the American Journal of Epidemiology, as quoted by the Daily Mail. The research is the latest in a series of studies that show regular exposure to sunlight may have anti-cancer effect by stimulating the production of vitamin D in the skin.
Laboratory tests showed the breast cells can convert vitamin D into a hormone that has anti-cancer properties. Canadian researchers compared 3101 patients with breast cancer with 3471 healthy women who did not develop tumors.
Each participant asked how much time they spend outdoors between April and October during the four stages of their lives: adolescence, twenties and thirties, forties and fifties, and from age 60 to 74.
The results showed that women who are at least exposed to sunlight 21 hours a week in their adolescence tend to suffer 29 percent fewer cancers than those who received one hour of sunlight a day.
For women who spend the most time outdoors in their forties and fifties, the risk is down 26 percent and for those over 60 years, sunlight reduces the risk of tumors by 50 percent.
Meanwhile, one study found men who get the recommended amount of vitamin D tend to have a heart attack or stroke fewer.
Research conducted in the United States that followed nearly 119,000 adults over the past two decades. The results found that men who received at least 600 IU (International Units) of vitamin D vitamin D per day 16 percent less likely to float the heart problems or stroke than men who got less than 100 IU. However, researchers at the Harvard School of Public Health found no pattern among women,

Experts warned the findings should be balanced in terms of risk of skin cancer from sun exposure.
