How do the beds and booths work?
Indoor tanning, if you can develop a tan, is an intelligent way to minimize the risk of sunburn while maximizing the enjoyment and benefit of having a tan. We call this SMART TANNING because tanners are taught by trained tanning facility personnel how their skin type reacts to sunlight and how to avoid sunburn outdoors, as well as in a salon.
Tanning beds and booths basically imitate the sun. The sun emits three kinds of UV rays (the ones that make you tan). UV-C has the shortest wavelength of the three, and is also the most harmful. The sun emits UV-C rays, but then it's absorbed by the ozone layer and pollution. Tanning lamps filter out this type of UV rays. UV-B, the middle wavelength, starts the tanning process, but overexposure can cause sunburn. UV-A has the longest wavelength, and it completes the tanning process. Tanning lamps use the best ration of UVB and UVA rays to provide optimal tanning results, with a lowered risk of overexposure.
