Ultraviolet radiation (UVR) causes the 3 major forms of @entity1489 : @entity1491 ; @entity957 ; and @entity320 . Public awareness of the risk is not optimal, overall compliance with sun protection is inconsistent, and @entity320 rates continue to rise. The risk of @entity1489 increases when @entity1 overexpose themselves to sun and intentionally expose themselves to artificial sources of UVR. Yet, @entity1 continue to sunburn, and teenagers and adults alike remain frequent visitors to tanning parlors. Pediatricians should provide advice about UVR exposure during health-supervision visits and at other relevant times. Advice includes avoiding sunburning, wearing clothing and hats, timing activities (when possible) before or after periods of peak sun exposure, wearing protective sunglasses, and applying and reapplying sunscreen. Advice should be framed in the context of promoting outdoor physical activity. Adolescents should be strongly discouraged from visiting tanning parlors. Sun exposure and @entity560 status are intertwined. Cutaneous @entity560 production requires sunlight exposure, and many factors, such as @entity2118 , season, and time of day, complicate efficiency of cutaneous @entity560 production that results from sun exposure. Adequate @entity560 is needed for bone health. Accumulating information suggests a beneficial influence of @entity560 on many health conditions. Although @entity560 is available through the diet, supplements, and incidental sun exposure, many @entity1 have low @entity560 concentrations. Ensuring @entity560 adequacy while promoting sun-protection strategies will require renewed attention to @entity1 's use of dietary and supplemental @entity560 .
