From the Times’ Well Blog:
eople 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.
“What this shows is that the brain is in fact responding to UV light, and it responds in areas that are associated with reward,” said Dr. Bryon Adinoff, a professor of psychiatry at the University of Texas Southwestern Medical Center and an author of the study. “These are areas, particularly the striatum, that we see activated when someone is administered a drug or a high-value food like sugar.”
Ugh, another reason for the state to ban tanning. It’s like a drug!
In any event, I think this is why the Jersey Shore season in Italy was boring–they couldn’t tan, and were in withdrawal.
