Personalized cotton harms human skin
Experts advise not to skimp and replace conventional linen or silk to satin. In their view, such a replacement would help preserve youthful skin.
From America dermatologist Dr. Dennis Gross opinion that cotton pillowcases gradually cause skin aging and lead to early wrinkles. Scientist explains the fact that while people sleep creates pressure on the cushion, thus traumatizing the skin. And even if the cotton from the cotton, the situation is compounded by the largely because of friction occurs between the surface and skin pillows person. Also, the aging of the skin is caused loss of collagen, which is absorbed during sleep in the pillowcase. Namely, the substance responsible for youthful skin.
“The Permanent Mission of pressure on the pillow leads to skin injury, but it is also exacerbated by the rubbing of cotton pillowcase,” said the doctor. “It can lead to wrinkles, as well as the skin loses collagen, over time, responsible for elasticity. Silk same, among other things , worse absorbs liquid, the skin has to be wetted during sleep. ”
But Dr. Gross agree not all Dermatologists. They argue that no evidence proved that he did not cotton underwear is harmful to humans. Skeptics also recommend scientist draw more attention to global issues, and not waste time wasted on such trifles.
“Far more useful to stop smoking and to reduce time in the sun,” such a statement was made a member of the British Association of Dermatologists doctor Shernaz Walton, responding to the words of Dr. Gross. Thus, the need for an integrated approach to save youth and elasticity of the skin.
It turns out that not only hurts cotton underwear during sleep. Previously, scientists have found that sleep while the light of extremely dangerous, especially for children. If a child is asked to leave parents included light on the night, adults in no case should carefully the request of children.
Scientists have determined that the main danger is sleeping with the light on so-called “gene timers.” They regulate the processes of sleep and wakefulness. Thus, if the child soldiers to sleep while the light in his genes happen to crash.
To prove this theory, researchers had to conduct a series of experiments on mice. Several rodents included sleeping with the lights, and the rest in complete darkness. Those mice, who were sleeping when the light became more troubled times, they appeared sleep disorder. Moreover, they did not have a clear cycle. They bombarded and wake at different times. A rodents, filling in the dark, had no faults in a cycle of sleep and wakefulness.
