Gourt Home::Gourt :: Sunbed
A sunbed is a device emitting ultraviolet radiation (usually UVA, but recently also UVB) used for cosmetic reasons (to induce an artificial tan).
Because of several adverse effects on human health, the World Health Organization does not recommend the use of UV tanning devices for cosmetic reasons. For example, using a sunbed without goggles may lead to a condition known as arc eye.
Dangers
UV radiation from sunbeds, particularly UVB, may cause cancer by altering the structure of the DNA. UV radiation can cause premature aging, including wrinkles, and also can have a detrimental effect on the immune system.
While the dangers of UVB are widely recognised, it has been convenient to regard UVA as 'safe'. UVA has less chances of burning, it has been called the "bronzing light," but it is clearly associated with inducing aging changes in the skin and in promoting the development of skin cancer.
History
Tanning beds were brought to North America by German scientist Friedrich Wolff in 1978 and rose to popularity in the mid-1980s. Since then, tanning beds have been a common way to tan without having to spend hours and hours in the sun's unpredictable radiation.
