When to protect your skin
UV rays are their strongest from 10 am to 4 pm Seek shade during those times to ensure the least amount of harmful UV radiation exposure. When applying sunscreen be sure to reapply to all exposed skin at least 20 minutes before going outside. Reapply sunscreen every two hours, even on cloudy days, and after swimming or sweating.
Protecting your eyes
UV rays can also penetrate the structures of your eyes and cause cell damage. According to the CDC, some of the more common sun-related vision problems include cataracts, macular degeneration, and pterygium (non-cancerous growth of the conjunctiva that can obstruct vision). • Wear a wide-brimmed hat To protect your vision, wear a wide-brimmed hat that keeps your face and eyes shaded from the sun at most angles. • Wear wrap-around style sunglass with 99 or higher UV blockEffective sunglasses should block glare, block 99 to 100% of UV rays, and have a wraparound shape to protect eyes from most angles.
Using the UV index
When planning your outdoor activities, you can decide how much sun protection you need by checking the Environmental Protection Agency's (EPA) UV index. This index measures the daily intensity of UV rays from the sun on a scale of 1 to 11. A low UV index requires minimal protection, whereas a high UV index requires maximum protection. -This information provided courtesy of U.S. Department of Health and Human Services
