The warmth of the sun on your skin and the healthy-looking tan it can produce may be appealing. Sunshine is rich in vitamin D and may help guard against colds and flu and some diseases, including certain cancers. When you overdo it, you may get a sunburn. The sun's rays can penetrate unprotected skin and cause premature wrinkling and increase your risk of skin cancer. Your objective should be to get a moderate amount of sun exposure without burning. Keep a few ground rules in mind before heading outdoors.
Sunscreen
Apply a broad-spectrum, water-resistant sunscreen 30 minutes before going out in the sun. Broad-based spectrum protects your skin from both ultraviolet A (UVA) and ultraviolet B (UVB) rays.
Sun Protection Factor
The American Academy of Dermatology says it's best to apply a sunscreen with a Sun Protection Factor (SPF) of 30 or higher to all areas of your skin that will be exposed to the sun. Make sure you give special care to your ears, nose, face and shoulders. Remember to reapply sunscreen every two hours or after swimming.
Protective Clothing
Wear protective clothing when you are outdoors. Long-sleeved shirts and pants can prevent the sun's harmful rays from reaching your skin. A wide-brimmed hat and sunglasses offer extra protection to your face and scalp.
Timing
Stay out of the sun during the midday when ultraviolet rays are the most intense. This is typically between the hours of 10 a.m. and 4 p.m. A good indicator of the sun's strength is to glance at your shadow. If you are taller that your shadow, move into the shade.
Location
Some outdoor locations make you more susceptible to sunburn than others. The AAD cautions that sun exposure can be especially harmful when you are near water, snow, and sand. These environmental elements reflect and intensify the damaging rays of the sun, which can make your skin more vulnerable to sunburn.
