I wish I could reverse the damage I've already done to my skin after too much time spent in the scorching sun, in search of a tan. It's seems unfair that a tan is so temporary -- yet its damage is everlasting. And it seems crazy that so many people are still searching for a tan -- when it has become so clear that is it so harmful.

As many as 60,000 people a year die from too much sun -- mostly from malignant skin cancer -- according to the World Health Organization (WHO). About 48,000 deaths are caused by malignant melanomas, and 12,000 deaths are caused by other kinds of skin cancer. And 90 percent of these cancers are caused by ultraviolet light from the sun. Cancer is not the only side effect of sun exposure, though -- serious sunburn, wrinkling, eye cataracts, growths on the flesh of the eye, cold sores, and other illness can result from the sun.

We all need some sun -- the vitamin D that is produced in the body by the sun helps to prevent disease and immune disorders. But too much is dangerous and sometimes deadly. Yet almost all ill effects from the sun can be prevented. And the WHO has released a report that advises people to seek shade, to use sunscreen with an SPF of at least 15, and to stay out of tanning salons. The report operates under the premise that sunscreens be used not to prolong sun exposure but to protect the skin when exposure is unavoidable.
