Sun Tan Parlors and Skin Cancer
The suntan industry has long been guilty of misrepresentations and outright lies. The National Institute of Health has noted that after UVA suntan treatments changes in the white blood cell count of helper to suppressor cells reflects the same defective reversals as that found in HIV patients. This got something like a page 12 notation in the Chicago Tribune and little attention after that. Skin cancer is the most common cancer in the United States and the 7th leading cancer killer. The incidence increases every year.
This year, with the help of what appears to be several misguided medical groups, the suntan industry is promoting tans to treat vitamin D deficiency - a disease which is not normally known to exist in the industrialized world! These groups cite associations with diseases that have yet to be proven, such a colon cancer. Think about it. How many people with colon cancer have worn red sweaters. Might we infer that red sweaters cause or at least predispose one to colon cancer? Shall we conclude that an arbitrary level of vitamin D which is not found normally in humans is preferable to skin cancer? Shall we conclude that 1/2 truths are better than no truths so we should change our habits to accommodate the marketing objectives of a private industry?
And while we are at it, may we remember that the love affair with sun tans is less than 100 years old compared to the millenia of human existence where the advantages of Darwinian selection determined skin color? I suggest we all do ourselves a favor: enjoy the sun for its healthy benefits (chiefly mental) and wear hats, shirts and shorts this summer. As for suntan parlors: let's throw them in with General Motors.
