Sunlight and Reduced Risk of Cancer: Is The Real Story Vitamin D?
Ready for everything you thought you knew to get turned upside down? Sunlight increases survival in early stage melanoma. “What??” you say. That demonic, cancer causing, avoid at all costs and wear SPF 100 to get the mail sunlight? When it comes to physiology, I always boil it down to a common question: What were we designed for?

Do you think our bodies were designed to be out in the sun for long periods of time? I think most would agree that the answer is yes. And remember, back then you couldn’t live in northern Canada with light skin and hop on a America West flight to head south for the winter–you stayed in the geographical region your body had adapted to.
