When people say they crave the sun and are addicted to tanning they may not be stretching the truth.
A P53 gene, also known as the suntan gene, may partly explain why people become addicted to tanning.
Scientists report that the gene stimulates the production of pigment in the skin, causing it to darken. The resulting suntan protects the skin from potentially cancer-causing UV light.
When the gene triggers the tanning process it also boosts the release of endorphins, one of the body's "feel good" chemicals.
That may be why people get so hooked on tanning.
Bronzed Tanning Salon co-owner Janette Stanley said, "We have a lot of clients that come in, maybe try us one time, then turn around, come out and say 'I need a package, this is great'. It's relaxing, kind of takes you into another world."
Researchers hope to be able to identify people who are at greatest risk of developing skin cancer and repair their gene response to the UV light.
