Q. All I ever hear about the sun is how dangerous it is. But, when I was a kid, my mother used to tell me to get out in the sun and play. Did my mother give me bad advice?
(I've devoted a lot of space to the dangers of sun exposure. I believe I owe the sun a couple of columns to make up for this. Here's the first one.)
Most public health messages have focused on the hazards of too much sun exposure. Ultraviolet (UV) rays, an invisible component of sunlight, can cause skin damage, cataracts, wrinkles, age spots, and skin cancer.
