Although we know that solar radiation, specifically increased exposure to Ultraviolet A rays (UVA), is the primary cause of the malignant melanoma or skin cancer, some scientists are suggesting that a moderate exposure to the sun may be beneficial to us in the prevention of other forms of cancer and diseases.The reason for this is that the main source of Vitamin D for humans is the exposure of the skin to sunlight. Vitamin D3 is produced when one of its precursors in the skin reacts with Ultraviolet B rays (UVB). It only takes about 10-15 minutes, at least twice a week, for the skin to produce adequate amounts of Vitamin D. This would be at any time of the year in the tropics, and during spring and summer in temperate regions. This doesn’t happen in areas near the arctic circle and during winter in temperate regions. That is when scientists are saying more exposure to the sun may outweigh the risks.
Although scientists have found that the incidence of major internal cancers increases from north to south, they also saw that the survival rate is significantly higher for those living in southern latitudes. And this has been related to the higher exposure to UVB since it has been proven that Vitamin D can be beneficial in the prevention of certain diseases.
I myself, love the sun, being from the Tropics. It just gives you a sense of life and adds brightness to your day...of course, in moderation.
