title: Double exposure: natural and artificial ultraviolet radiation exposure in beachgoers.
abstract: BACKGROUND
  Although the beach is a high-risk environment for ultraviolet light exposure and subsequent skin damage, little is known about beachgoer tanning habits outside the beach setting. Our purpose was to evaluate indoor tanning and additional, nonbeach sunlight exposure in a beachgoing population.
  
  
  METHODS
  We conducted an epidemiologic survey.
  
  
  RESULTS
  There was more use of indoor tanning salons among sunbathing beachgoers who applied little or no skin protection from the sun (50.8% [31 of 61 respondents]) compared with nonsunbathing beachgoers (22.7% [5 of 22 respondents]). In addition to increased use of tanning salons, we observed that poorly protected sunbathers tanned at locations other than the beach on a regular basis (50.8% [31 of 61 respondents]) more than nonsunbathers did (9.1% [2 of 22 respondents]).
  
  
  CONCLUSIONS
  Beachgoing sunbathers often used both natural sunlight and tanning beds, subjecting themselves to two forms of ultraviolet radiation exposure.
