According to statistics released by the Skin Cancer Foundation, nearly 120,000 cases of melanoma are diagnosed each year. In addition to those startling statistics, previous studies have shown that those individuals under the age of 30 who regularly tan (at least ten times per year) are eight times more likely to develop malignant melanoma than those who don’t; yet, the tanning industry is booming. A study completed by University of Texas Southwestern Medical Center may have just figured out a key component to this seemingly vicious cycle of sun damage: addiction.

UT Southwestern’s pilot study monitored the brain circulation of participants while tanning. The participants completed two tanning sessions–one that exposed them to regular ultra violet light and another that used special filters to block the damaging UV rays.
