Background: Recent studies have identified reinforcing properties associated with tanning and suggest a possible physiologic mechanism and addiction driving tanning behavior.
Objective: This article attempts to synthesize the existing literature on tanning and addiction to investigate possible associations.
Methods: We investigated a variety of substance dependence models to define what constitutes dependence/addiction and to determine how current studies on tanning meet these criteria.
Results: In some individuals, tanning has met Diagnostic and Statistical Manual criteria for a substance-related disorder or tanning-modified Cut Down, Annoyed, Guilt, Eye-opener criteria. Trial studies have demonstrated the induction of withdrawal symptoms in frequent tanners.
Limitations: Additional studies are needed to investigate the associated dependency and addiction more fully and to elucidate its similarities to other better-known addictive syndromes.
Discussion: Tanning is a problem behavior, both as a health risk and as a possible dependency. Future studies, especially in the area of cognitive mapping and cue-related stimuli are needed. Imaging studies may be important in elucidating whether the same areas of the brain are involved in tanning addiction as in other addictive syndromes.
