Research information on how much sleep a human should have.

Sleepless thinking

It is a fact that research has found that how long a person can sleep is related to their genetics. Generally, our sleep is controlled by the central part of the brain. Scientists believe that this may be related to genetics, and therefore sleep is planned and occurs at birth.

These new ideas have been further confirmed by studies of the electrical activity of the brains of twins. When twins sleep, the onset time they take to fall asleep, the different stages of their sleep, and their duration, there are many similarities between them.

Sleep is a state of unconsciousness that is different from the waking state of sensory perception. As a result, the ability to immediately perceive some external changes is temporarily lost, resulting in surprising changes in brain activity.

There are two types of sleep.

Rapid eye moment stage

Non-rapid eye moment stage

The first type of sleep accounts for 25 per cent of the total sleep time. In this state, the eyes are moving slowly here and there with the eyelids closed, and dreams occur in this state. In this state, the heartbeat, breathing, and blood pressure increase slightly.

The Non-rapid eye moment stage that follows this decreases blood pressure, followed by the heartbeat, breathing, and the synchronous movement of the muscles in the joints also decreases.

The basic reason that induces sleep is still not known exactly. Many factors are needed to prove it scientifically. Researchers say that sleep occurs in the background of a biochemical system. Chemical substances found in various parts of the brain play an important role in sleep by helping to transmit electrical impulses.

Sleeping time

Can you go without sleep for a long time?

Generally, it is very difficult to cope with sleep; sleep comes automatically when the body is tired. Only a very few people have the habit of sleeping both during the day and at night. According to some studies, researchers say that taking a short nap during the day keeps the body healthy.

We may think that women are weaker than men and can endure sleep deprivation because they are physically stronger, but the truth and research results are different.

When we studied people who need to stay awake, such as border guards, traffic wardens, drivers, factory workers, and many others, it was found that women tolerate sleep deprivation much more easily than men.

This is attributed to the higher fat content in women's bodies. Compared to younger people, people over 40 are generally more likely to suffer from sleep deprivation.

Researchers say that people in their 20s and 30s can get by without sleep for a while because they are healthier at a young age, and they can get by without sleep. Young people can tolerate a few days of sleep deprivation without any problems.

However, prolonged sleep deprivation usually causes mental decline. Some people also have the potential to become depressed. Although this sleep may help compensate for the wear and tear on the body and brain, more research needs to be done to scientifically prove how it actually benefits physical health.
