Sunburn is more
frequent than it should be, because many people think it’s just bright sun we
need to worry about. Actually it’s the sun’s ultraviolet or “UV” rays, 80% of
which penetrate thin clouds, haze, and
fog. These rays can create short and long-range damage regardless of
how bright the sun is shining.

In the 1970s, we
learned that some of the chemicals we used were destroying the ozone in the
upper atmosphere which protects us against UV rays. We’ve changed some of our
chemicals, but it will take generations for the ozone to strengthen, and
we’re still more at risk than our parents and grandparents.

UV damage to the
skin isn’t just temporary. Excessive
exposure over time, regardless of our own skin type, can lead to sagging and
wrinkling of the skin and premature age spots. It will increase the risk of
skin cancer.

Illness and some medications can increase our
sensitivity to UV rays. If you’re not
sure whether this applies to your illness or a medication you’re taking,
check with your physician.

special protection against the sun.
Who are they, and why do they need such protection?
