Sleep is a state of the body in which the activity of many organs is reduced, and brain activity is minimal. This phenomenon is observed not in all living things, but only in birds, fish, mammals and some other animals. Scientists still cannot fully explain the purpose and physiology of sleep, but today it is already known that sleep is necessary for rest, processing information, and for other reasons.

What is sleep?

A person devotes the third part of his life to sleep, this is one of the most important processes for life: not getting an opportunity for rest, the body dies, as if there is a lack of food or water. Sleep is one of the most mysterious states that still raises many questions among scientists. Since ancient times, this phenomenon has attracted curious researchers: the ancient sages put forward many erroneous theories about the causes and purpose of sleep.

For some time it was believed that this was due to brain poisoning. But today it is known that this condition is not pathological and is necessary for the normal functioning of the body's systems. Sleep also has a number of other functions. The study of this phenomenon continues, and perhaps scientists will still give a more complete explanation of this phenomenon.

Why do you need sleep?

The main function of sleep is restorative. Throughout the day, the body accumulates stress, its cells are destroyed, tissues and organs get tired, and the brain has to solve a huge number of problems. During the day, he is engaged in maintaining the hormonal background, the rhythm of the heartbeat, breathing, while it is necessary to pay attention to both perception and other activities. During wakefulness, waste products accumulate in the body, and energy reserves are quickly spent. A huge amount of information is accumulated in neural connections, but there is no time to organize it.

Sleep solves all these problems by giving the body rest. At this time, the brain does not turn off, but goes into a different mode: it systematizes information, replenishes glucose reserves, removes products of internal processes, forms new proteins, and restores cells. As a result of processing the information received during the day, memories are ordered and data is archived, and the number of neural connections increases. It has been proven that sleep stimulates memory, makes it easier to memorize the desired material.

In addition, sleep restores immunity, which is reduced by many factors during wakefulness. When a person sleeps, certain cells are activated in his body - T-lymphocytes, which cope with infections and colds.

With a lack of sleep, the body begins to malfunction: cells do not receive enough nutrients and die, memory and attention deteriorate, the work of many organs, mucous membranes and glands is disrupted, the immune system cannot cope with pathogenic bacteria and viruses, pathological conditions and diseases develop from - for the malfunctioning of the body systems.
