Most people love the way they look with a tan, whether it's deep and dark or just a sun-kissed glow. Tanning beds damage eyes through cataracts, macular degeneration and eye disease. Because UVB rays are shorter, they cause superficial damage to the outer layers of the skin however, they do contribute to both aging and cancers also. Tanning beds emit UVA rays that are 12 times the intensity as the sun, so users are 2.5 times more likely to develop skin cancer, according to the Skin Cancer Foundation. UVA rays damage keratinocytes skin cells, the outer part of the epidermis, and do contribute to and may initiate skin cancer. Tanning beds compromise your immune system, so your body cannot fight off disease. Although tanning beds give off three times more UVA rays than the sun, they reduce the UVB exposure by 40 percent, according to Elizabeth Carruth of Vanderbilt University.ĭangers Both UVA and UVB rays cause premature aging, skin cancer and damage to your eyes.

UVA and UVB Beds Tanning beds that are mixed are typically 93 to 99 percent UVA bulbs and one to seven percent UVB bulbs.
These beds maximize your color, but you should already have a good base tan before using these beds. UVA tanning beds are more expensive per minute, however. If you want to get a quick tan, the UVA only beds will give you a tan in only three to five visits of 20 minutes. UVA tanning beds are comprised of 100 percent UVA bulbs. UVA Only Beds UVA bulbs cause the production of melanin from melanocyte cells, deepening the color of your skin.

UVA rays are long rays that penetrate deep into the skin.
Ultraviolet rays are not as long as visible light, so you do not know you are being exposed. UVA versus UVB Ultraviolet rays are forms of radiation from the electromagnetic spectrum, or the light spectrum.
