Scientists are now putting forth the theory that people who love to tan just might be addicted to the UV rays tanning provides. There’s a belief that tanners might be getting an endorphin rush from the sun and they found mice who were denied their daily sunning would miss it.

This would explain things like the Tan Mom or the GTL of the Jersey Shore miscreants. Some scientists, however, believe that over-tanning can be linked to other disorders like OCD. In any case, they still recommend that you get a cancer screening once a year.
