Somnologist from Sydney, Australia, Olivi Arezzolo, has uncovered the dangerous effects of sleep deprivation. Her words are quoted by the Daily Mail.
The first signs of sleep deprivation are bruises and bags under the eyes, Arezzolo said. "Although to some extent these symptoms can be inherited, sleeping less than eight hours can exacerbate the problem," the expert emphasizes. Bags under the eyes occur when dry skin due to lack of sleep traps water in order to stay hydrated.
Also, due to lack of sleep, the skin does not produce enough collagen, which prevents the appearance of wrinkles. So, inadequate sleep leads to premature aging and deterioration of the skin. Studies have shown that people who sleep less than five hours a night have a 30 percent reduction in skin barrier regeneration.
“As a result, the skin becomes dull and lifeless,” stresses Arezzolo.
Scientists have also found that people who are sleep deprived are less satisfied with their appearance. “It is collagen that affects the firmness or flabbiness of your skin,” says the somnologist. "Research shows that 70 percent of collagen is synthesized during deep sleep."
Poor sleep causes the body to release the stress hormone cortisol, which can lead to dehydration. As a result, the skin becomes dry. In addition, after such a dream, a person's immune system weakens and acne appears. The somnologist advises sleeping seven to nine hours a day and drinking plenty of water so as not to dehydrate the body.
Earlier, nutritionist and candidate of medical sciences Irina Berezhnaya told why it is dangerous to work without lunch. According to her, neglecting lunch during the working day is fraught with a change in the regime for the body, which gets used to a certain routine. This can lead to dire consequences psychologically and physically.
