Little sleep, reduced adaptation to stress
During sleep, the brain recovers from the day’s stress and exhaustion. But to achieve this, the brain needs a sufficient number of hours of sleep. Otherwise, states of irritability and a reduced ability to adapt to stressful situations appear, which favors the appearance of depression.
The recommended bedtime is 10 p.m
Sleeping late has the same effect. According to the American study, teenagers who go to bed after midnight have a 24% higher risk of depression than those who fall asleep before 10 p.m. Following the same study, it was found that teenagers who go to bed later than midnight face a 20% higher risk of thinking about suicide, compared to those who go to bed before 10:00 p.m. Suicidal tendencies are more common in girls and teenagers who do not feel loved by their parents. The American study was conducted on a number of over 15,500 young people between the ages of 12 and 18. “Parents believe that a child who has reached the age of 14-15 knows how to manage the time spent in front of the computer or the TV. The body needs rest, and fatigue causes teenagers to have all kinds of impure thoughts,” says Dr. Gangwish.
Specialists have also reported other problems associated with lack of sleep in the past. They showed that insufficient sleep increases the risk of obesity in adolescents, because insufficient rest prevents the body from producing a sufficient amount of leptin, a hormone that blocks appetite. At the same time, when the body is deprived of sleep, another hormone, ghrelin, is produced in excess, which has the role of increasing appetite. Lack of sleep also increases the blood sugar level, which predisposes to diabetes.
