Sun Tanning
.]]
Sun tanning is the darkening of the skin, especially of fair-skinned individuals, in response to exposure to ultraviolet radiation from sunshine (or a sunbed).
The darkening of the skin is caused by an increased release of the pigment melanin into the skin's cells. This pigment is produced by cells called melanocytes, and protects the body by absorbing harmful solar radiation.
A suntan has often been seen as attractive, though this is variable and susceptible to the whims of fashion. The wish of some to look well-tanned, combined with the modern concern about overexposure to the sun, (which has been linked to melanoma) has led to the production of products that give the appearance of a suntan without any exposure to the sun. (See fake tan.)
A study by a Dr. Anthony Liguori and others, published in the July 2004 issue of the Journal of the American Academy of Dermatology, Part 1, suggests that indoor sun tanning may be addictive. The UV content of the sun's rays stimulate the production of endorphins, resulting in a natural "high".
Studies undertaken by George Washington University and Sydney University suggest that the UVB component of sunlight damages the skin.
To avoid sunburn, sunscreen, tanning oil or creme are used.
Other meanings
''Suntan'' was also the code name of an early prototype to the SR-71 Blackbird reconnaissance aircraft by the Lockheed Skunk Works. The aircraft was in development during the 1950's, it was to be powered by LH2. A LH2 powered aircraft was consider too dangerous and expensive to maintain and the project was canceled, the research was redirect using more conventional fuels and resulted in the SR-71.

Post-mortem tanning
Do only dead or alive cells tan, or both? - Omegatron 19:35, May 9, 2005 (UTC)
''Apparently from the article, cells don't become tanned, melatonocytes produce the pigment which makes skin look tan. Some produce the pigment only in response to the radiation, some don't need it to produce pigment. But I would suspect that the cells need to be alive to produce pigment.''
''I wonder how long the pigment remains before it fades - does it have a half life? I suppose that a dead black person would eventually fade and look albino, but would that happen before or after the skin decomposes? I'd guess that melatonocytes remain active for some time after general biologically recognized death, and if so, then a dead white person exposed to the sun might still tan for some time.

:Uh. I meant the dead skin cell layer on alive people, versus the deeper layers of alive cells. - Omegatron 14:07, Jun 11, 2005 (UTC)
Dangers of tanning
Is sunlight just as harmfull to your skin as artificial UV rays from a sun tanning bed? I am curious whether or not it is actually safer to use a sun tanning bed rather than getting a tan from a natural source.
Also, is there a threshold of UV exposure, such as staying out longer than X hours in the sun? Or something along those lines?
''The state of the art isn't likely near where one could claim that Radiation from a UV tube is healthier than Solar light at sea level, but a responsible Tan Salon should at least be able to handle the necessary precaution in order to avoid excessive exposure. The Sun's timer is preset a little too long for most non-third world populations to rely on. The Sun would probably be healthier, if you dilligently kept track of your levels of exposure, and took into account cloud cover and other atmospheric fluxuations. Other than just natural Sunlight, I could rationalize tanning bed use to set base in preparation for a holiday spent closer
