When I lay in the sun, I don't wear sunscreen because it's so full of chemicals. I take this 15 minutes front, 15 minutes back, now in the shade. If I do that every day within a week, I've got a lovely tan. And I've got that tan from the UVB rays. And the UVB rays are blocked by sunscreen. The UVB rays are the rays that hit the skin and convert a form of cholesterol just under the skin to vitamin D. And our DNA has 2,500 receptor sites for vitamin D. And there are many people today lacking vitamin D because they're not out in the sun. What does vitamin D do? It actually helps in the absorption and assimilation of calcium. So our bones and our teeth deteriorate if we're not getting enough vitamin D. These sunscreens and vitamin D deficiency, which sunscreens cause, are contributing to basal cell carcinoma, which is actually the deadly form of skin cancer. If you burn your skin eight to ten times in your lifetime, that can certainly double your risk of skin cancer. We should never harm the skin by overdoing the sun. But we've got another problem today, and that is underdoing the sun.
