Seek shade whenever possible. Shade structures such as trees and umbrellas provide year round protection. Although trees do not offer complete sun protection, they provide about 60 percent blockage from the sun's rays. Clothing can physically block out the sun's harmful rays and should be one of the first lines of defense against sun exposure. Sunglasses should block out 100 percent of UVA and UVB radiation to protect the eyes from damage.
Hats are the best way to minimize UV radiation exposure to the face, head, ears, and neck.
Use broad-spectrum sunscreens whose active ingredients block UVA and UVB rays. Sunscreens should be used every day, including cloudy days. They should be applied liberally and evenly before going out into the sun and should be applied frequently, especially after swimming. Avoid tanning salons. Artificial UV radiation is just as bad for your skin as sunlight.
