Sleep is divided into slow, or normal, and fast, or paradoxical, which alternate throughout the night.
The first time REM sleep is recorded 40–90 minutes after falling asleep, occurs 4–5 times per night and lasts from 6 to 20 minutes, occupying only 20–25 percent of all sleepy oblivion.
During slow sleep, energy connections are restored, brain proteins and nucleic acids are synthesized, and the so-called growth hormone is released. Children truly “grow in their sleep.” The ancients noticed this. During the REM sleep phase, the brain not only analyzes the information received, but also draws up a program for the future. REM sleep is usually accompanied by dreams - at these moments the heartbeat and breathing increase, and the eyeballs begin to move under the eyelids.
“Cinema in a dream” protects a person from the difficulties of life. If in the evening the situation seems unbearable and the problems seem unsolvable, then as the day comes, there is hope for new plans. “In our sleep we can sneeze away all our troubles,” the Chinese say. The wisdom that is closer to us is more laconic: “The morning is wiser than the evening.”
The duration of sleep is very individual and varies depending on temperament, age, health, etc.
It’s difficult to say exactly how much genius in the field of fine art slept, but perhaps we can single out two personalities who, in addition to other features, are also known for their sleep patterns:
1. Leonardo da Vinci. The genius of the High Renaissance practiced “polyphasic” sleep: he slept for 15-20 minutes every 4 hours. Thus, he spent only 2 hours a day on sleep; he devoted the rest of the time to work.
2. Salvador Dali. One of the most famous representatives of surrealism also did not sleep for several hours in a row. He took the tray, a large key in his hands and sat down on a chair. When entering the deep sleep phase, his hands unclenched, the key fell and hit the tray, Dali woke up and immediately went to draw what he had dreamed.
