Studies shed new light on the destructive properties of ultraviolet rays Scientists prove
The scientists found that ultraviolet rays have a more devastating effect than once thought.
The sun emits UVA (short wave) and UVB (long-wave) radiation. Previously it was believed that these rays do not destroy the deep layers of the skin. New research Kings Kolleldzh in London found that UVA rays are much more carcinogenic, which underlines the need to avoid sunlight and solarium.
According to Professor Anthony Young damage increase due to the fact that, penetrating into the epidermis, it dissipates in the opposite direction. "Basal layer, responsible for cell division, that is, their birth, requires protection to prevent malignant degeneration. Ultraviolet rays at most shortwave, while the long wavelength is 5%, and their intensity depends on the height of the sun. The effect of the UVA rays is quite stable throughout the year, which explains the need to avoid the sun at least at lunch time, "- said Professor Young.
