Careless exposure to the sun can be harmful. UV rays damage the skin, create vision problems, cause allergic reactions, depress immune systems and cause other skin concerns. Follow the guidelines below to keep yourself safe:

Limit Time in the Midday Sun
The sun's rays are strongest between 10 a.m. and 4 p.m. Whenever possible, limit exposure to the sun during these hours.

Seek Shade
Shade is a good source of protection, but keep in mind that shade structures (e.g. trees, umbrellas, canopies) do not offer complete sun protection. Remember the shadow rule: Watch your shadow. No shadow, seek shade!

Wear a Hat
A hat with a wide brim offers good sun protection to your eyes, ears, face, and the back of your neck — areas particularly prone to overexposure to the sun.

Cover Up
Wearing tightly woven, loose-fitting, and full-length clothing is a good way to protect your skin from the sun's UV rays.

Wear Sunglasses that Block 99-100 percent of UV Radiation
Sunglasses that provide 99-100 percent UVA and UVB protection will greatly reduce sun exposure that can lead to cataracts and other eye damage. Check the label when buying sunglasses.

Always Use Sunscreen
Apply a broad spectrum sunscreen with a Sun Protection Factor (SPF) of at least 15 or higher liberally on exposed skin. Reapply every 2 hours, or after working, swimming, playing, or exercising outdoors. Even waterproof sunscreen can come off when you towel off, sweat, or spend extended periods of time in the water.

Watch for the UV Index
The UV Index provides important information to help you plan your outdoor activities in ways that prevent overexposure to the sun. Developed by the National Weather Service (NWS) and EPA, the UV Index is issued daily in selected cities across the United States.
