SUNLIGHT AND SKIN
For many people the appearance of a suntan is a reflection of health, vitality, and success. We are all subjected to advertisements containing suntanned people engaged in satisfying recreational activities. For those of us living in cold climates, the quest for warmth and sunlight can be very fierce. Many people spend all or part of the winter season in warmer climates. Returning home with an obvious tan is a way of announcing success and good health.
Unfortunately the effects of the sun, although very appealing, have a long-term impact on the skin that can be very dangerous, besides accelerating the skin’s aging process. Some researchers have suggested that much of the wrinkling seen in older skin is caused by sun damage—not by aging. In addition, many of the skin problems that older people experience may be influenced by the effect of the sun’s radiation.
It is important that you protect yourself from excessive rays of the sun by the use of sun hats and appropriately protective clothing as well as by sunscreen lotions. The higher the number (sun protective factor, SPF) of the lotion, the greater the protection. There are various kinds of sunscreens. Some individuals may be sensitive to the PABA (para-amino-benzoic-acid) contained in some sunscreens and therefore require one that is non-PABA-containing.
For those with very light skin, numbers 10-15 might be necessary, whereas for people with darker skin, numbers 5-10 may be adequate. Remember, suntan lotions without sunscreens are not protective and should not be used instead of sunscreens. Depending on the product, it may be necessary to reapply the lotion after swimming or if you have been perspiring. If you’ve experienced skin damage or illnesses caused by the sun in the past, it is essential that you take precautions and use a sunscreen.
