Limit time in the midday sun.
The sun's UV rays are the strongest between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the sun during these hours.
Watch for the UV Index.
This important resource helps you plan your outdoor activities in ways that prevent overexposure to the sun's rays. Developed by the National Weather Service and EPA, the UV Index is issued daily in selected cities across the country. While you should always take precautions against overexposure, take special care to adopt sun safety practices when the UV Index predicts exposure levels of moderate or above (Minimal: 0-2; Low: 3-4; Moderate: 5-6; High: 7-9; Very High: 10+).
Use shade wisely.
Seek shade when UV rays are the most intense, but keep in mind that shade structures (e.g., trees, umbrellas, canopies) do not offer com-plete sun protection. Students can easily remember the shadow rule: "Watch Your Shadow -- No Shadow, Seek Shade!"
Wear protective clothing. A hat with a wide brim offers good sun protection for your eyes, ears, face, and the back of your neck. Sunglasses that provide 99 to 100 percent UVA and UVB protection will greatly reduce eye damage from sun exposure. Tightly woven, loose fitting clothes will provide additional protection from the sun.
Use sunscreen. Apply a sunscreen of SPF 15+ liberally and reapply every 2 hours, or after working, swimming, playing, or exercising outdoors.
Avoid sunlamps and tanning parlors. Sunbeds damage the skin and unprotected eyes and are best avoided entirely.
