What is a sleep

People often give sleep a mystical aura. It is believed that in it there is communication with the world of the otherworldly, with the spirits of subtle plans, with what cannot be accessed in the ordinary state. Indeed, sometimes dreams are true or clarifying some of the problems that people have in the real world. It is known that D. I. Mendeleev saw his table in his dream, as did the discoverer of the structural formula of benzene.

Physiologists approach the study of this phenomenon in a more practical way. They believe that sleep is physiologically necessary for us, as a rest from the information obtained from the outside.

Brain – Computer

Imagine that your brain gets information from five senses and in that looks like a huge computer. Gigabytes of data are “pumped” into RAM and analyzed for 12, 14, 16 or 18 hours a day. Such work requires tension, even if one doesn’t notice it.

It is in the dream that a kind of analysis of the received, the removal of the unnecessary, the sending of material into long-term memory occurs. From the morning you feel fresh and rested. Ready to receive the next information “charge”.

The rest of the body

All organs of a person need rest to varying degrees. In addition to the above information processing in the brain, the rest of the body’s systems also require attention.

If you are deprived of sleep for 72 hours, hallucinations can begin, and if you extend insomnia, an imminent lethal outcome is possible.

In sleep the maximum relaxation of muscles occurs. The heart calms down and works in an easy mode for itself. The muscles are released from accumulated during the day fatigue, and the psyche from possible stresses.

Therefore, a healthy sleep is necessary for each of us as a way to rest and analyze the experience gained during the day.

How much to sleep

can’t be answered unequivocally. One people need 10 hours, and others feel great after 4. Physiologists along with doctors highlight averages in the region of 6-8 hours at a young age, about 6-7 hours at maturity and 4-5 in the elderly. The older the person gets, the need for sleep is less. Such an interesting pattern, still thoroughly unstudied.
