Tanning
Technology - Tanning beds whether they are stand up or lie down designs, use the effects of ultraviolet radiation (UV Rays) on the human skin. When ultraviolet radiation enters our skin, it stimulates the inner layer of the skin, called the dermis. When the dermis is stimulated it produces melanin (pigment that darkens the skin) and brings this substance to the upper layer. For those that have darker skin, they’ll have more melanin than people with lighter skin and people suffering with albinism have no melanin. In tanning beds, there are specially designed lamps that produce the same kind of ultraviolet radiation like the sun - radiation after all, is energy. Some versions of UV lamps are used in forensic science to detect dried blood in crime scenes. And some are used in our tanning beds. When tanning beds were first introduced, the beds produced both UV-A and UV-B Radiation but when UV-A was discovered to be the culprit of some forms of cancer, the more recent tanning bed models switched to lamps that emit less UV-A and more lamps producing UV-B.
