For the last 30 years or so, doctors (dermatologists in particular), health officials, beauty experts and many product companies have been demonizing the sun. They’ve told us to avoid it because without sunscreen, exposure to the sun’s rays will damage skin and cause cancer.
But this oversimplification distorts the facts. In the past few years, numerous studies have shown that optimizing your vitamin D levels may actually help prevent as many as 16 different types of cancer including pancreatic, lung, breast, ovarian, prostate and colon cancers. And the best way to optimize Vitamin D levels is through safe, smart and limited sunscreen-free exposure to the sun.
For hundreds of thousands of years, man has lived with the sun: Our ancestors were outdoors far more often than indoors. We developed a dependence on sunshine for health and life, so the idea that sunlight is dangerous does not make sense. How could we have evolved and survived as a species, if we were that vulnerable to something humans have been constantly exposed to for their entire existence? Is it possible that our bodies are made in such a way that the sun is really a lethal enemy?
Not in my opinion. Like all living things, we need sunshine, and it feels good for a reason. Much as plants harness the sun’s rays through photosynthesis, our bodies use sunlight to help the skin produce the vitamin D it needs to build bones, quell inflammation, bolster the immune system and protect against cancer (including skin cancer).
