Sleep is the physiological need not only of man, but of any representative of the animal world. At this time, a lot of processes take place in the brain and in the body, for example, the accumulation of energy reserves, the production of hormones responsible for puberty and human growth, body temperature, pressure, the nature of nervous activity several times a night, and so on.

Scientific research has shown that sleep has two phases, cyclically repeating 4 to 6 times a night every 90 to 120 minutes. The first of them is called the orthodox or the phase of slow sleep, the second - paradoxical - fast. Being in the first stage, the sleeper does not react to the surrounding, his breathing is slowed down, and all the biochemical processes in the body are practically stopped. In the paradoxical period, the electrical impulses of the brain are analogous to the biorhythms of day life, the breathing becomes more frequent, the pupils move, the body temperature and blood pressure increase, gastric juice and adrenaline are more quickly released, this phase is characterized by high activity of the brain. If you wake the sleeper during this period, he will not feel rested. It lasts about 10 minutes, in which a person dreams. Nighttime biorhythms remain unchanged, even if you do not sleep, and the phase of fast sleep signifies the onset of a sharp sleepiness.

It has been experimentally established that, on average, a person's biological need is 10 hours. Depending on the type of person and physical condition, this figure may fluctuate. Lack of sleep during the week is usually the cause of depression, pain and burning in the eyes, rapid fatigue, increased appetite and irritability. Chronic lack of sleep lowers immunity and leads to mental disorders, since the restoration of body resources occurs only in this state.
