First off, I don't use wikipedia. Nor did I locate the following in it, which means that someone at wikipedia might use what I am about to share with you. My problem is I wish to share this with you but am concerned when new information comes out then wikipedia is using me. lol! (Tim, this is why I frown on wikipedia. Wikipedia = encyclopedia. An encyclopedia is a large volume of information.)
Azlan naeem, the National Institutes of Health states the following about one disease that might be of interest to you:
Ultraviolet rays have suffiecient energy that they can damage the DNA of the skin cells causing various forms of cellular dysfunction .The most dreadful is skin carcinoma which occurs commonly in light skinned individuals , Burns also occur due to damage to the skin structures and subsequent inflammation . However UV rays exposure is essential for skin health and to guard against vitamin D deficiency . vitamin D is necessary to keep bone strengh.UV rays are sometimes dangerous to the eyes in some predisposed individuals and may lead to diminution of vision

Avoid Skin Cancer! Practice SAFE SUN!
• Skin cancer is the most common cancer in the United States.
• Melanoma is a deadly skin cancer that is caused by UV radiation from the sun or artificial tanning booths.
• Melanoma is linked to excessive sun exposure in the first 18 years of life.
• Avoid sunburns by practicing SAFE SUN!
What about your body’s need for vitamin D? Remember you need only 15 minutes of sun three times a week to produce vitamin D. You can also take in vitamin D through vitamin-D fortified foods, salmon, or a multivitamin that has 600-800 units of vitamin D.
