Addicted to tanning

(CBS) -- Some people just can't resist getting tan...and now scientists think they know why.

Researchers in Texas looked at people's brain activity while they were inside a tanning bed. They found blood flow patterns in the brain were similar to what happens in drug addicts. Scientists say, like addiction,
tanning may create a reward in the brain and could explain why, despite the dangers of skin cancer, some people use tanning beds.
