Summer in South Florida: The Dangers of the Sun's Damaging Rays.

Sun and sand are the perfect couple, right? But beware: When you come between them, you're at high risk of getting burned. That's because sand reflects 25 percent of the sun's rays, giving unsuspecting beachgoers an extra dose of UV exposure.

Skin-Saving Advice: Wear sunscreen the right way. That means wearing a broad-spectrum sunscreen (one that blocks both UVA and UVB rays) of at least SPF 30. Use a minimum of an ounce (enough to fill a shot glass). According to the American Academy of Dermatology (AAD), most people only apply 25 to 50 percent of the recommended amount. The AAD suggests applying sunscreen to dry skin 15 minutes before going outdoors and reapplying every two hours, or after swimming or sweating. The Environmental Working Group's sunscreen guide tells you what to look for and what to avoid.
