It was John Denver who sang that sunshine on my shoulders makes me happy. Dr. Martin thinks of that song whenever the sun is shining.

Recently Dr. Martin shared some news that the FDA was recalling lots of sunscreens because of their carcinogenic effect. Now, a new study is showing that people who use sunscreen are much more susceptible to melanoma than people that don't use it.

Join Dr. Martin as he shares a combination of studies on sunshine, why it works, and what it does when you get it on your skin. Exposure to the sun is so good for you, and there’s no need to be afraid of it.
