A tan bed or sunbed is a device, which emits ultraviolet radiation to create a cosmetic darkening of the skin. Tan beds use many fluorescent lamps having phosphor blends emitting ultra-violet rays in a range similar to the sun. The exposure time changes from bed to bed with a maximum of 20 minutes. People can start with shorter spans and increase upto maximum in a month's time. Each tan bed must have a Recommended Exposure Schedule and the rating of the original lamp certified for it. Lamp which is certified must be used. The lamps have a life of 800 to 1000 hours.

Use

In the United States, tanning is done from January to June. When summer begins, they have a considerable tan and can enjoy the outdoor. Tanning is done for cosmetic reasons, good feel and minor muscular pain reasons. Tanning lotions and bronzers are prevalent. In Europe as sunshine is less, tan beds are used all throughout the year. Using for the entire year causes quick sunburn, but Americans prefer it as a shorter span causes more reddening. A tan can be built up by tanning 3-4 times a week. Then it has to be maintained by tanning 2-3 times a week. Tanning gives a dark brown color to the skin. This is highly appreciated and serves as a source of attraction.

Comparison with the Sun

The tan produced by a bed is not as deep as the sun. The excessive Ultra-Violet radiation from the Sun affects the immune system and causes premature aging and wrinkles. Its advantages are the production of Vitamin D and the treatment of eczema or skin disorders. In the sunlight it is not possible to control the light the body is exposed to, which may lead to sunburn. But in tan beds it can be controlled. If sunlight does not tan the body, tan beds also can not tan as both use the same process to tan the skin. Eyes can't themselves resist Ultra-Violet Light and may be damaged in tan beds. So it is essential to use eye protection. Thus, if used with precaution tan beds can prove beneficial than sunlight.
