March 14, 2007 -- Despite the dangers and the health warnings, some people feel like they just have to tan.
Now a new survey shows what dermatologists have long suspected -- that tanning can be an addictive behavior, similar to a drug or alcohol addiction.
The finding may shed light on why public health messages about the risks of sun exposure have been ignored by so many people, especially teens and young adults.
"If tanning is addictive, as our study suggests, it helps explain why education alone will probably not stop high-risk tanning behaviors -- similar to how the 'don't drink' and 'don't smoke' messages often fail to change behaviors," researcher Robin L. Hornung, MD, MPH, says in a news release.
A Tanner's High?
Previous research suggests that exposure to ultraviolet (UV) light, either from indoor tanning beds or the sun itself, causes the release of endorphins, which can produce euphoric sensations. The euphoria is the same as the "runner's high" that people often experience with intense exercise.
In the new study, 385 students at the University of Washington at Seattle were surveyed in an effort to find out if tanning rose to the level of an addictive behavior.
Four of the survey questions, designed to determine if exposure to UV light was an addiction, were modified from a screening tool for alcohol abuse, known as the "cut down, annoyed, guilty, eye-opener" (CAGE) questionnaire. Those who reported "yes" to two or more questions were considered to have a positive screening. The questions were:
- Have you ever felt you ought to cut down on tanning?
- Have people annoyed you by criticizing your tanning?
- Have you ever felt bad or guilty about your tanning?
- Have you ever thought about tanning first thing in the morning?
Seventy-six percent of the female study participants and 59% of the males reported tanning their skin on purpose. Forty-two percent of the females and 17% of the males reported tanning indoors at tanning salons.
Women tanners were more likely than men to score positively in their CAGE response, suggesting UV light addiction. Of the respondents who acknowledged purposely tanning, 22% of the women and 8% of the men had positive CAGE results.
