Being in Georgia people know when summer comes around. People find themselves enjoying the extra hot weather. Do you know how important it is to put sunscreen on your skin? There are at least 1,000,000 cases of skin cancer diagnosed in the United States EVERY YEAR!
There are some keys to using sunscreen lotion/spray that people need to be aware. Sunscreen should be applied every day to exposed skin, and not just if you are going to be in the sun. Cloudy days can be actually be more harmful to your skin than you think. UVB rays cannot penetrate glass windows, but UVA rays can damage your skin in the car. Here is the breakdown for UVA vs. UVB rays:
Long-wave solar rays of 320-400 nanometers, (billionths of a meter). You’re almost never safe from exposure to UVA rays as they can go through light clothing and even your windshield, so if you’re outside you’re getting exposed to UVA rays. These rays are responsible for aging. They are less likely than UVB to cause sunburn but UVA penetrates the skin more deeply, causing wrinkling and leathering of the skin. Sounds appealing?!
Short-wave solar rays of 290-320 nanometers. UVB rays are more potent than UVA in producing sunburn. Therefore these rays are considered the main cause of skin cancers. UVB “tanning ray”, stimulate the melanocyte cell to produce the brown pigment melanin, producing a suntan as a defense against UV radiation.
Scientists and Researchers agree that a person should apply susncreen to dry skin 15 to 30 minutes BEFORE going outdoors. Be sure to apply it to any potentially exposed skin. As I have learned recently… Don’t forget that your lips can get sunburned. Sunscreens/sprays should be reapplied every two to three hours or after swimming/sweating. Big Note: “Water-resistant” sunscreens will lose their effectiveness after 40 minutes in the water. Sunscreens rub off as well as wash off, so if you’ve towel-dried, reapply sunscreen for continued protection.
