What are the dangers of sun exposure?
The immediate danger of too much sun is sunburn. If you looked at sunburned skin under a strong microscope, you would see that the cells and blood vessels have been damaged. With repeated sun damage, the skin starts to look dry, wrinkled, discolored, and leathery. Although the skin appears to be thicker, it actually has been weakened and, as a result, it will bruise more easily.
However, the sun’s most serious threat is that it is the major cause of skin cancer, which is now the most common of all cancers. Doctors believe that most skin cancers can be avoided by preventing sun damage.
