Stay Out of the Sun! by Stephen Bucaro

Many people like to take off their clothes and lay out in

the sun for hours, thinking sunscreen lotion will protect

them. They follow the recommendation of using a sunscreen

with a minimum SPF of 15. However, sweat will cause the

sunscreen to wash off and become blotchy, allowing exposure

to ultraviolet radiation.

Note: In 1998, epidemiologist Merianne Berwick of the

Memorial Sloan-Kettering Cancer Center in New York

evaluated of several studies on sunscreen use. Her

conclusion: There is absolutely no evidence that the use

of sunscreen prevents skin cancer. In fact, five of the

studies found that sunscreen users actually had an

increased risk of melanoma.

A recent study suggests that 15 minutes of exposure to

sunlight each day will cause your skin to produce all the

vitamin D your body needs to remain healthy. Here in Arizona,

15 minutes of exposure to sunlight can kill you.

If you must go out in the sun, wear protective clothing

regardless of how hot you feel. Even if you are sweating

like Niagara Falls, always wear long sleeves and a hat.

Don't forget to cover areas like your neck and hands. Don't

walk over bright surfaces like concrete for long periods of

time. Your face can be exposed to ultraviolet radiation

reflected from the ground.

If you like to go outdoors, go out in the morning or

evening when the sun is 45 degrees or less above the

horizon. At this angle, sunlight is filtered through a

thick layer of atmosphere. You know it's safe to be outdoors

when objects shadows are longer than the objects are tall.

Before the appearance of the ozone layer, the surface of

the earth was bathed in ultraviolet radiation making it

impossible for life to exist. Unfortunately, modern

industrial society has created ozone destroying CFC

molecules, putting life on earth back in danger.
