Many people in the current rhythm of life experience an acute shortage of time and try to solve the problem in different ways. Someone cuts the hours spent on their beloved friends and hobbies, and someone visits the thought: "And if you do not sleep all night?" What will happen in this case, we consider further.
Healthy sleep duration
First of all, let's remember how long a healthy sleep should last. For an adult, its duration is 6-8 hours, but it all depends on the characteristics of the body. There are also people who need a 5-hour rest. Children tend to sleep longer, but with age its duration decreases.
Reasons for insufficient night rest
1. Physiological features.
They can cause insomnia in people of any age: in infants and the elderly. These include: hormonal failure, diathesis, joint diseases, hypertension, enuresis, etc.
2. Stress.
With excessive stress on the nervous system, the production of sleep hormone - melatonin - decreases and the secretion of adrenaline increases. Therefore, any problems, crises and difficulties can lead to insomnia.
3. Failures in biological rhythms.
All processes in the human body begin to slow down by about 8 hours. If the desire to fall asleep is ignored, the biological rhythm goes astray, and doing so later becomes problematic.
The consequences of lack of sleep. Nervous system problems
The lack of proper rest becomes a blow to the nervous system. Such situations often occur with students. If you stay up all night, what will happen to their studies? The result is a failed exam, even though the guys learned hard material. Why it happens? The fact is that a lot is recorded in memory precisely during deep sleep, so even in a limited amount of time, try to comply with the regime.
Problems with the whole body
Scientists have proven that chronic sleep deprivation is becoming a prerequisite for a number of other diseases, such as stroke, obesity, hypertension and diabetes. A tremendous load on the heart occurs, there are problems with the skin, nails and hair. The consequences of a sleepless night are reflected in the appearance of a person. Therefore, if you want to look decent, start with relaxation.
Stress hormone
The experiments showed how much the human psyche changes depending on the time of lack of sleep. The first day he makes almost no effort to stay awake, on the second he appears distracted, aggressive. The third day it is difficult to maintain vigor without help from others, as there is another result of lack of sleep - hallucinations; a person loses a healthy appearance, looks exhausted, tortured. Further, the experiments in most cases are terminated, since there is a high probability of death.
Scientists have tried to explain this pattern. Firstly, special chemical processes have been discovered that occur in a person who has not slept all night and causes mental suppression. On the second day, changes in the hormonal background, disturbance of neural connections in the cortex. 3-4 days of lack of sleep threaten the death of brain cells, significantly increases the load on the internal organs (especially the heart). The fifth day of insomnia is a direct path to death, accompanied by irreversible changes.
A clear answer to the question: "What is the maximum amount of time a person does without sleep?" - still failed to get. The fact is that all the experiments carried out cannot exclude the possibility that the people participating in them did not enter into shallow sleep for short periods of time. This often happens if you do not sleep all night. What will happen to the body during superficial sleep? This condition is a short break in the brain, which can occur during normal human activity. Internal organs at this time also rest (of course, inferiorly).
How does chronic lack of sleep affect the body?
We will consider the problem of chronic lack of sleep separately, since in this case a person experiences a daily lack of sleep, although he sleeps for a short period of time. Deficit gradually builds up and can result in serious trouble.
Chronic lack of sleep (as a rule, rest of less than 6 hours every day for a week) is equivalent to a two-day lack of sleep. If a person lives in this state for a long time, oxidative processes develop that affect memory and learning. People age faster, the heart rests less, the heart muscle wears out faster. Chronic lack of sleep for 5-10 years leads to insomnia due to depression of the nervous system.
A person becomes susceptible to a number of diseases, since the result of chronic lack of sleep is insufficient immunity (the number of lymphocytes that confront infections is reduced).
Reduced stress tolerance also occurs with chronic lack of sleep, and increased irritability and grouchy should also be included here. Therefore, if you want to always be a positive and cheerful person, observe the sleep regimen.
Thus, the lack of night rest can indeed become a serious problem for the body. Insomnia will certainly affect human health. It is better not to test yourself for strength, not to ask the question: “And if you do not sleep all night, what will happen?” - and allocate enough time for regular sleep at the appointed hours.
