• Wearing Protective Clothing People who work outside should wear clothing that protects their skin, including long-sleeved shirts, hats and pants. Outdoor recreational activities should be scheduled before 11:00 A.M. and after 2:30 P.M., when the concentration of ultraviolet light is decreased by 70 to 80 percent. • Avoiding Tanning Booths Tanning booths have advertised that by using UV (A type ultraviolet light) a "safe" tan is obtained. There is no such thing as a "safe" tan. Tanning is a response of the skin to injury. UVA does cause less redness than UVB, but like UV it may induce skin cancer and photoaging (drying, wrinkles and pigment changes). UVA is actually used experimentally to produce skin cancer in mice. Since 1986, about 2 million people a year have visited tanning booths. This will contribute to an increase in the number of skin cancers we will see over the next 10 to 20 years. • Being Aware of Skin Changes and Getting Early Treatment Besides sunscreens, avoiding ultraviolet light and wearing protective clothing, preventive measures include early detection and swift removal of precancerous lesions.
