Every tenth feels unwell at the time of falling asleep: aches, tingling, spasms. This so-called syndrome of tired, or restless, legs (RLS) causes a person to constantly move, preventing him from sleeping.

Lack of sleep hits the immune system from different angles. In particular, it enhances the negative effects of stress. Lack of sleep reduces the number of natural killers – immunocytes, which attack and destroy cancer cells. Chronically sleep-depriving people experience changes that reduce resistance to infection.
Nedosyp increases in young people the risk of pathologies more typical for the elderly, including type 2 diabetes, hypertension and memory dips (sclerosis), causes signs of insulin resistance, an early stage in the development of diabetes. Levels of the thyroid hormone and hormones that regulate insulin production are approaching “elderly” values.
Lack of sleep harms not only health, but practically all aspects of human life. Authoritative researchers found the following negative effects.
Mood is spoiling. After analyzing dozens of publications devoted to the lack of sleep, the psychologists June Pilcher and Allen Haffcatt discovered the following. When people were asked to assess their own mood in points from 0 to 100, those who did not sleep usually chose a number less than 10. For well-rested people, this figure averaged 50.
Learning is difficult. A study by the Canadian University of Trent showed that an inadequate, irregular sleep greatly hinders learning, up to 50% reducing the amount of new information that our brain can process.
Reduced sexual activity. In one of the interviews, all 30 patients with sleep apnea evaluated all aspects of their sexual life below the norm. After getting rid of this sleep disorder, their rates improved dramatically, especially in two areas – the intensity of sexual desire and the ability to achieve orgasm.
The emotional stability decreases. According to scientists, depression is stimulated by the shortage of dreams associated with intermittent sleep. Probably, their “viewing” is a mood-regulating process that helps cope with anger and other negative emotions, believes Dr. Rosalind Cartwright.
