Ultraviolet Rays and the Ozone
When the sun comes out, it's time to head outdoors. But, as we all know, too much sun can be a bad thing. This is the reason our parents have been slathering us up with sunscreen since we were babies. Do you know some of the serious dangers from spending a long time under those rays? Check out some of the hazards and a few tips to avoid them.
Ultraviolet Rays and the Ozone Layer
The ozone layer soaks up most of the sun's harmful ultraviolet (UV) rays, but how much depends on the time of year and the weather. Thanks to chemicals that aren't environmentally friendly (such as chemicals called chlorofluorocarbons, AKA CFCs), the ozone has thinned in certain areas. In fact, over Antarctica there's a hole three times the size of Australia! Does this mean more UV rays are making it down to earth? Yes, but if we keep doing our part, the ozone will gradually rebuild itself.
Health Effects From Sunburn and Ultraviolet Rays
Young people often spend more time outside than adults, but peeps under the age of 18 are at the greatest risk for sunburn. What some people might not be aware of is that too much sun can cause, not only skin cancer, but several other serious afflictions that might haunt you for the rest of your life. Here's a list of some of the risks from catching too many rays.
Melanoma Skin Cancer - This is the most serious form of skin cancer. It's also one of the fastest growing types of cancer in the US, with one in 87 people developing it each year. That's an increase of 1,800 per cent since the 1930s! Scientists believe there might be a link between childhood sunburns and developing melanoma later on in life. If it's caught in time, it is almost curable. However, it can spread very quickly.
Nonmelanoma Skin Cancer - This kind of skin cancer is rarely fatal, but that doesn't mean it should be overlooked. If left untreated, nonmelanoma skin cancer can cause major health problems. The two types of nonmelanoma skin cancer are Basal Cell Carcinomas, which are fleshy non-spreading nodules or bumps, and Squamous Cell Carcinomas, which are rapid growth tumors that can spread to other parts of the body.
