Hey readers....I created this blog to explain to you what effect tanning can cause.....So before I can sit here and discuss the harmful effects of tanning equipment and increased sun exposure, one should first be familiar with the components of ultraviolet light and how it can affect your skin. Sunlight contains two different types of ultraviolet (UV) light. UVA and UVB. UVA rays consist of longer wavelength that penetrate deep into the dermal layer of skin. Limited exposure to UVA rays causes skin to tan, however, most experts agree that overexposure to UVA can lead to long-term skin damage. UVB rays wavelengths are much shorter, affecting the outer most layer of skin. "Burning Rays" are know as UVB rays and are very dangerous. Tanning beds and sun lamps generally emit 93%-99% UVA radiation. That is 3 times the UVA radiation given off by the sun!
