As tanning bed users ignore dangers, addiction concerns grow very dangerous..
Many are aware of the health risks. Though any form of ultraviolet light increases skin cancer risk, people younger than 30 who use tanning machines increase their risk of skin cancer by 75%, according to the International Agency for Research on Cancer, which is affiliated with the World Health Organization. The melanoma rate among young women nearly tripled from 1973 to 2004, a period in which use of tanning beds increased significantly, a National Cancer Institute study showed.
For some, tanning resembles not just a bad habit but an addiction, says dermatologist David Fisher, author of an editorial earlier this month in The New England Journal of Medicine. In an April study of 229 tanners published in the Archives of Dermatology, up to 39% met commonly used criteria for addiction. People who met the addiction criteria were far more likely than others to be anxious or depressed, and to use other addictive substances, such as drugs and alcohol, the study says.
In another small experiment with frequent tanners, Feldman found that blocking endorphins can produce symptoms similar to narcotic withdrawal, such as nausea, sweating and nervousness, Feldman says.
