False Security

From Health Day News:

Tanning booths may be contributing to the meteoric rise in skin cancers seen worldwide.

Ok this next statement is a little less obvious:

While tanning outdoors is distinctly unhealthy, tanning beds may be even worse because people have a false sense of security from the sun tan parlors. These establishments generally use the longer wavelength ultraviolet A, which doesn't show a visible burn until very high doses.People think it is safer, but in fact, the longer wavelength penetrates much deeper, hitting the blood vessels, causing a decrease in immune function.

That's it. If I added any more excerpts I will have posted the entire article.
