The rays are strongest between 10 a.m. Wear clothing with a thicker weave or apply sunscreen under a thin, porous shirt. In addition, a hat with a full, wide brim gives added protection to the face, neck and scalp, and sunglasses help protect the eyes from damage.

And 4 p.m., so staying indoors during these times is the best protection. Also, use lip balm with an SPF rating. Slather on sunscreen about 20 minutes before going in the using about an ounce (the size of a shot glass) to cover your entire body.

Before heading out, suggests the American Society for Dermatologic Surgery, remember to. A typical cotton T-shirt offers protection equivalent to only SPF 6, far below the commonly recommended minimum of SPF 15. Reapply every two to three hours spent outdoors. Wear the right sunscreen every day.

Use products labeled for broad-spectrum protection -- to help block ultraviolet A (UVA) and ultraviolet B (UVB) rays -- and with a minimum protection factor (SPF) of 30.
