- Hats On!
- </hdr><body>
- <p> Ozone depletion is cause for caution, but it's no reason to
- stay barricaded inor put on an astronaut suit before venturing
- outside. Excessive exposure to the sun's ultraviolet (UV) rays
- has always been dangerous; the ozone problem just adds to the
- risk. Says NASA's Michael Kurylo: "We're not talking about a
- single exposure to a death ray. It takes repeated exposure over
- long periods of time."
- </p>
- <p> Even if there were no atmospheric damage, an estimated
- one-sixth of all Americans would still develop skin cancer
- during their lifetime. Most cases are curable, if detected
- early. The 4% to 8% loss of ozone over the past decade could
- raise the risk at least 15%. A significant increase in
- cataracts, which now afflict 1 of every 10 Americans, could also
- occur.
- </p>
- <p> As the ozone depletion gets worse, health risks will rise,
- but the odds of getting cancer or cataracts can be dramatically
- reduced by following guidelines that doctors recommended long
- before ozone depletion became a big issue. Their suggestions:
- </p>
- <p>-- When out in the sun for prolonged periods, wear
- protective clothing. That means choosing fabrics that have a
- tight weave and donning a wide-brimmed hat. A basecap is not
- adequate because it leaves the delicate rims of the ears
- exposed.
- </p>
- <p>-- In summer, when comfort calls for shorts and T shirts,
- use a broad-spectrum sunscreen with a sun protection factor of
- at least 15.
- </p>
- <p>-- Minimize the time spent in the sun between 10 a.m. and
- 3 p.m.
- </p>
- <p>-- Wear sunglasses when outdoors in bright sunlight. Ask
- for ones that are treated to absorb UV radiation or that meet
- the American National Standards Institute Guidelines for eye
- wear. Poorly designed sunglasses that do not block UV rays could
- do more harm than good. Under dark lenses, the pupils dilate,
- making it easier for UV light to damage the delicate membrane
- of the retina.
