Sun Safety is the practice of taking simple steps to reduce overexposure to UV rays while still enjoying the outdoors.
- After applying sunscreen, you should give it 20 to 30 minutes to dry before going outside. It takes this long after application for the chemicals to start working. Letting the sunscreen dry also helps ensure that it stays on your skin.
- If you've been in the sun or water, you should reapply waterproof sunscreen every two hours.
- Check the sunscreen’s expiration date. Sunscreen without an expiration date has a shelf life of no more than three years, but its shelf life is shorter if it has been exposed to high temperatures.
- For the most protection, wear a hat with a brim all the way around that shades your face, ears, and the back of your neck. A tightly woven fabric, such as canvas, works best to protect your skin from UV rays.
Did you know?
Surfaces such as sand or water reflect up to 85 percent of the sun's damaging rays. It's especially important to protect your skin and eyes around these surfaces.
The sun is strongest -- and most dangerous -- between 10:00 a.m. and 4:00 p.m.
A sunscreen's Sun Protection Factor (SPF) number refers to the factor by which it enhances a person's natural sun protection. If someone normally burns in 20 minutes, then a sunscreen with an SPF of 15 would protect them for 300 minutes (SPF 15 x 20 minutes = 300 minutes).
Clouds and pollution often give a false sense of protection. Even on cloudy or hazy days, unseen ultraviolet sun rays can cause unexpected sunburn and skin damage.
