For the last few decades we have talked about little else other than why you should stay away from sunlight. We realize just how real skin cancer is and the risks associated with it so we do everything we can think to do to keep it from happening to us. We choose the highest SPF sunscreens we are able to get and then slather on layers and layers of it. We wear huge hats. Even during the hottest conditions of the year we make ourselves put on long sleeves and pants. We tend to stick to the shade–some individuals may also carry parasols and umbrellas just to make sure they have exactly no contact with the sun. Now we are beginning to understand that sunlight can really help us. Can direct sunlight actually help you?
