When it comes to shielding your skin from UV radiation, not all apparel is created equal. You need to know how to select a UV-safe wardrobe, whether it's from your closet or from specially made clothing.

Despite the overwhelming brightness of summer days, only about 48% of sunlight is visible to your eyes. An additional 46% is invisible infrared radiation. The remaining 6% consists of two types of invisible ultraviolet radiation—UVA and UVB.

UV radiation is the dangerous component of sunlight. UVB causes sunburn, premature aging, and skin cancer. UVA is also involved in sunburn and skin cancer. Although you are more susceptible to damage from UV radiation if you are light-skinned or you live at higher altitudes or near the equator, no one is immune to harm from UV radiation. And for those who try and stay out of the sun completely, if you have less than fifteen minutes a day of sun exposure, you will need extra vitamin D from your diet because sun exposure is the primary source of this vitamin. If you do not get enough vitamin D in your diet, talk to your doctor before taking any supplements.
