People who frequently use tanning beds experience changes in brain activity during their tanning sessions that mimic the patterns of drug addiction, new research shows. Scientists have suspected for some time that frequent exposure to ultraviolet radiation has the potential to become addictive, but the new research is the first to actually peer inside the brains of people as they lay in tanning beds. What the researchers found was that several parts of the brain that play a role in addiction were activated when the subjects were exposed to UV rays. The findings, which appear in the coming issue of the journal Addiction Biology, may help explain why some people continue to tan often despite awareness about risks such as skin cancer, premature aging and wrinkles.
