Updates for responsible sun exposure behavior and photoprotection in the south.

In Louisiana, the "Sportsman's Paradise," and throughout the Southern United States (US), outdoor pursuits are among the most popular physical activities, despite well-documented associations between excessive solar ultraviolet (UV) radiation and skin cancer. Although there have been recent advances in broad-spectru m sunscreens, photoprotective clothing, and photoprotective sunglasses, few peer-reviewed publications have focused specifically on recommendations for responsible sun behavior and photoprotection for residents of the South. In response, the objectives of this review will be (1) to describe the adverse health effects of excessive UV radiation exposures; (2) to review recent cohort studies of public perceptions regarding sun behavior and photoprotection; (3) to identify special populations at increased risks of UV-associated skin cancers; and (4) to recommend responsible sun behavior and photoprotection strategies. Internet search engines were queried with the key words as search terms to examine the latest references on photoprotection and the epidemiology of UV-associated skin cancers and other adverse effects of UV-radiation exposures. Observational studies have demonstrated that the public knows little about proper sunscreen selection and UV protection, and cohort studies have identified populations at increased risks of UV-associated skin cancers. Southerners should avoid intense sunlight, wear photoprotective clothing, wear sunglasses, and select the right sunscreen for their skin type. Physicians should counsel their patients about responsible sun behavior and photoprotection and encourage them to take advantage of recent advances in the development of more effective broad-spectrum sunscreens and photoprotective clothing and sunglasses for themselves and their children.
