UV rays are more dangerous than previously thought, experts warn after studies made it clear connection between the amount of ultraviolet radiation from the most remote from bronzaj salons and cancer incidence. So far, it is believed that tanning beds by radiation emitted by them, apartamente de vanzare bucuresti are responsible for wrinkles and other signs of skin aging, but after studying the effects of sunlight on the skin, it sounded the alarm.
Anthony Young, a British expert in skin diseases, studied how human skin behaves under the action of two types of ultraviolet radiation A – with large wavelength – and B – with short wavelength, sample case being selected from among young men and women without health problems.
“Bronzaj salons tend to argue that ultraviolet type A is safe, but that’s just nonsense ‘
Young said, adding that UV radiation may be more carcinogenic than thought before. Regarding spectrum sunlight, it is present ultraviolet radiation, researchers at King’s College, London, warned that not only the sun at noon is dangerous, but that high levels of UV radiation are present in the morning, to late afternoon.
He also cautions that are endangered even motorists or passengers of buses and trains, because, unlike the claims of legend, apartamente de vanzare bucuresti ultraviolet radiation penetrate through glass. Professor Anthony Young illuminated with UV light in the skin of 12 young British then took samples dermal and it checked for any effects that may lead to cancer.
The tests showed that ultraviolet type B, which usually are blamed for triggering skin tumors, affecting more than the surface layers of the skin. They are renewed by new cells every four weeks. By contrast, ultraviolet type A associated with wrinkles, took effect more profound than thought before. Some of the cells were affected by UVA split grew faster and faster, which indicates an increased risk of skin cancer.
“UVB light remains the most important in terms of how DNA is damaged, but UVA apartamente de vanzare bucuresti has a significant contribution”
Anthoy Young said in the study published in the Journal of Investigative Dermatology. His findings are particularly alarming because, unlike UVB, UVA rarely burn skin, and that borrowing more aching “bronze” and people are not aware of the magnitude of the effects they have on them. Professor Michael Kimlin , an Australian expert on the health effects of the sun, says the
“Everything scientists tell us is that we examined, for years the wrong wavelength.”
It shows that all studies have focused on UVB, which are known to cause skin burns, an important risk factor in skin cancer.
“We know that UVA causes premature skin aging, but so far not made the connection between them and cancer. Now we know that there is no need to burn your skin will risk to health ”
Australian researcher concludes. Warnings arrive precisely at a time when there is an explosion of dermal cancers, malignant melanoma, the most deadly form of skin cancer. Modern obsession for appearance as “Sport and Health” may be to blame for the multiplication of cases.
World Health Organization cautions that bronzaj salons, although their equipment emits a comparatively small amount of apartamente de vanzare bucuresti UVA and UVB, is a greater cancer risk than cigarettes. Alert was released, and tanning perception must change: no UV “good” and “bad”. To some extent, ultraviolet are clearly defined danger.
