Winter’s Coming: Stock up on Sunscreen
"Don't put away the sunscreen in the winter just because the days are short and the sun is low in the sky," says Noreen Nicol MS, RN, FNP, Chief Clinical Officer at National Jewish Medical and Research Center. "Winter sports enthusiasts can face just as much risk of sunburn as summer sunbathers when exposed skin isn't protected."
Nicol explains that snow amplifies the burning potential of the sun by reflecting the ultraviolet radiation (UVR) that causes sunburns. At higher elevations, where skiers and snowboarders generally play, the thinner atmosphere screens out significantly less of the incoming UVR than it does at lower elevations.
Sunburn and other sun-caused damage to the skin increase the risk of developing skin cancer. More than 1 million Americans will be diagnosed with skin cancer this year. In addition, repeated sun damage causes cosmetic damage to the skin, which can include spider veins (those visible blood vessels on the side of the nose and on the cheeks), rough and thickened skin, age spots and wrinkles.
Ms. Nicol offers several tips for avoiding sun damage and skin cancer during winter months.
- Sunscreen. When selecting a sunscreen, look for the label "broad spectrum (UVA/UVB)" and a sun protection factor (SPF) of at least 15. "Sunscreen isn't fully effective right away," says Nicol. "For the best protection, apply sunscreen half an hour before going out in the sun. Then apply it generously and apply it often- don't forget your ears, neck and hands." Discard old or expired sunscreen.
- Lip Balm and Moisturizers. Many lip balms and facial moisturizers contain sunscreen as well. Make sure the ones you use contain sunscreens.
- Eye Protection. Wrap-around sun glasses and ski goggles with appropriate UV protection can protect both the eyes and the skin around them.
- Hat. Wear a wide-brim hat that protects the face and back of the neck.
- Peak Hours. The most significant sun exposure occurs between 10 a.m.-3 p.m. Either put on extra sunscreen then or take a break from the sun and get some lunch.
- Clothes. The most practical precaution against most UVR exposure is finely woven clothing. So is a new chemical additive: when placed in your washing machine, it will increase your regular clothing's SPF as well.
