The Real Killer in Sunlight -- UVA

"Dr. Dianne Godar of the U.S. Food and Drug Administration (FDA) has conducted a study indicating that UVA light -- not the UVB light that causes suntans and allows your body to produce vitamin D -- may be responsible for the melanoma epidemic.

What’s more, the UVA light, unlike UVB, can pass through window glass, meaning you can still be exposed to it while you are indoors or in your car.

UVB, on the other hand, appears to be protective against melanoma -- or rather, the vitamin D your body produces in response to UVB radiation is protective. Dr. Godar points out that the melanoma epidemic began long before sunbeds, and that the dramatic melanoma increase occurs primarily in indoor workers, not outdoor workers."
