Most women crave pure white skin, so that not a few who always avoid the sun. But they do not understand the benefits of sunlight behind it.
Whereas dark-skinned women because sun is often more fortunate, because it has a better chance to live long.
It turned out that sunlight is the main energy source to convert provitamin D contained in the skin tissue into vitamin D. In humans, nearly 90 percent of the formation of vitamin D was facilitated by the sun.
Vitamins are not just good for bones but also can prevent many deadly diseases. Among blood clots in the legs or called vein thromboses, as noted professor of oncology at Lund University in Sweden, Hakan Olsson.
The disease is mostly found in women and killed no fewer than 25,000 people each year. In a study conducted by Prof. Olsson of 40,000 women, revealed that vein thromboses appear more often in winter when the sun rarely appeared.
"Many believe frequent sunbathing could increase the risk of skin cancer. But the increase was not greater than other benefits, so that in general women who frequently sunbathe have a chance live longer," said Prof. Olsson was quoted as saying of Dailymail, Sunday (5 / 12 / 2010).
Another benefit of the sun according to Prof. Olsson is to prevent diabetes. Still based on research he did, Prof. Olsson concluded the diagnosis of diabetes in women is more often given in the winter than in summer.
However, other cancer experts to assess the results of research that has been presented in the Swedish Society of Medicine forum is too excessive. Ed Yong, a researcher from the Cancer Research UK warned that the threat of skin cancer should not be underestimated.
"Sunlight is good for humans and vitamin D are also good for bone health. But no evidence was strong enough that the benefits of vitamin D could offset the risk of skin cancer. The most important thing is to prevent skin cancer, make sure the skin is not burning when sunbathing," said Yong .
