Now they were trend-setters. No, it wasn't Coco Chanel, Bo Derek, or even Christie Brink- ley. They came thousands of years later. It was Helios and Ra - they were the original Sun Gods. But before we knew it, almost everyone had jumped on the bandwagon and become a Sun God or Goddess. But don't dare admit it if you are one. In today's society, wor- shipping the sun is strictly ta- boo. The mere mention of the word sun, and people slap on the 30 SPF sunblock and take cover in the shade. Gaps in the ozone layer are causing harmful Ultraviolet ra- diation (UV) from the sun to reach the earth's surface. There are three types of UV rays. The first is UVC rays, which do not reach the earth's surface. But UVB and .UVA rays, which do make their way here, are creating serious health risks. UVB rays are those which doctors were initially most con- cerned with. They cause the skin to burn, and can result in the development of skin cancer. Only recently have the harm- ful effects of UVA rays been dis- covered. They work in conjunc- tion with UVBs, breaking down the skin's elastin and collagen, ultimately resulting in prema- ture wrinkling and sagging of the skin. Diane Finkle of the Canadian Cancer Society, said there were an estimated 50,000 new cases of skin cancer reported in 1991. "But of those, only about 2,900 were cases of melanoma, which can result in death, be- cause the cancer spreads to oth- er parts of the body," she said. Although everyone should take precautions, there are some people who are at a higher risk of developing skin cancer as a result of sun exposure. Those with fair skin, blonde or red hair, and light colored eyes should be particularly cau- tious. Ms. Finkle said that while any sun damage to the skin is irreversible, the early detection of sun spots and wearing a strong sunblock are vital. Measured by their Sun Pro- tection Factor (SPF), sunblocks allow a person to stay out in the sun without burning, anywhere from two to 50 times longer, than if they were not wearing any protection. Most times, however, the gnd -d SPF refers only to protection from UVB rays. There is only one sunblock available in Canada, Photo- plex, which protects against both UVA and UVB radiation. The Canadian Dermatology Association advises adults to use a sunblock with a minimum SPF of 15. But for children, stronger precautions must be taken. Health and Welfare Canada es- timates that 60 to 80 per cent of exposure to the sun occurs be- fore the age of 18. As a result, they warn par- ents to use a sunblock with an SPF of 30 on children. The association does not rec- ommend, however, using sun- block on babies under six months old, as the chemicals are more likely to absorb into the skin. : Because babies are not born with a developed skin protec- tion system, it is best to keep them in the shade to avoid di- rect sunlight. Parents are also advised to use sunblock themselves, and on their children even on cloudy days, as 80 per cent of the sun's rays can still penetrate through. But skin protection is not the only area of concern when it comes-to sun exposure. The eyes are also very sensi- tive to Ultaviolet radiation. Years of exposure to the sun can result in the formation of cataracts in the lens of the eye. Short-term exposure can also result in a burning of the eyes, similar to that of the skin. Such a burn may result in eyes wa- tering and becoming irritated. To prevent such harmful damage, it is imperative to wear sunglasses that provide 100 per cent UV protection. Despite this recent fear of the sun and its apparent side- effects, the issue of ozone deple- tion is not a new one. "The depletion itself hasn't really gotten worse over the past 10 years. It's just that our awareness has increased," said Kathleen Hedley of Environ- ment Canada's Atmospheric Environmental Services. Around the same time as we began to learn of ozone deple- tion and the harmful effects of the sun, we were also intro- duced to the tanning bed. They produce Ultraviolet-A and B rays, enabling people to get an even tan in a shorter pe- riod of time. At first, this was favorable, until it was learned that UVA rays are in fact damaging to the skin. Kerri Scully and Roselyn Oli- ver of Gold 'N Glow in Port Perry, operate two tanning ds. Ms. Scully said many people prefer the beds because if used properly, they do not result in burning. She said they have many cus- tomers who use the tanning beds to build up a base and pre- vent a burn before heading south for the winter. Mrs. Oliver said they are cau- tious, never letting the same customer tan more than once a day. They also provide protective eye goggles, and advise first- time users not to sun their faces for the full half hour session. Ms. Scully said, however, that the number of people using the sun beds has decreased over the past six years. "But I don't think it's entirely because they're worried about skin cancer. It's a fad that dies down just like anything else," she said. But while tanning beds may be a fad, outdoor suntanning does not appear to be. Since it became fashionable in the 1920s, people just can't seem to get enough sunlight. But times, and the environ- ment, have changed. So, wheth- er we like it or not, pale skin is in.
