Many people in the modern rhythm of life experience an acute shortage of time and try to solve the problem in different ways. Someone reduces the hours spent on favorite friends and hobbies, and someone is visited by the thought: "And if you don't sleep all night?" What will happen in this case, we will consider further.
He althy sleep duration
First of all, let's remember how long he althy sleep should last. For an adult, its duration is 6-8 hours, but it all depends on the characteristics of the organism. There are also people who need a 5-hour rest. Children tend to sleep longer, but as they get older, the duration decreases.
Reasons for not getting enough sleep at night
1. Physiological characteristics.
They can cause insomnia in people of all ages, from babies to the elderly. These include: hormonal failure, diathesis, joint diseases, hypertension, enuresis, etc.
2. Stress.
In case of excessive stress on the nervous systemthe production of the sleep hormone melatonin decreases and the release 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 o'clock. If the desire to fall asleep is ignored, the biological rhythm goes astray, and it becomes problematic to do it later.
Consequences of lack of sleep. Problems with the nervous system
The lack of proper rest becomes a blow to the nervous system. These situations often happen to students. If they don't sleep all night, what will happen to their studies? The result is a failed exam, even though the guys studied the material stubbornly. Why is this happening? The fact is that a lot is fixed in the memory during deep sleep, so even with a limited amount of time, try to follow the regime.
Problems with the whole organism as a whole
Scientists have proven that chronic sleep deprivation is a prerequisite for the occurrence of a number of other diseases, such as stroke, obesity, hypertension and diabetes. There is a colossal load on the heart, 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 a rest.
Stress hormone
Experiments have shown 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, onthe second appears absent-mindedness, aggressiveness. The third day is difficult to maintain vigor without the help of others, as there is another result of lack of sleep - hallucinations; a person loses a he althy look, looks exhausted, tortured. Further experiments in most cases are stopped, since the probability of death is high.
Scientists have tried to explain this pattern. Firstly, special chemical processes were discovered that occur in a person who has not slept all night and cause suppression of the psyche. On the second day, changes in the hormonal background occur, violations of neural connections in the cortex. The 3-4th day of lack of sleep threatens with the death of brain cells, the load on internal organs (especially the heart) increases significantly. 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 can go without sleep?" - still couldn't get it. The fact is that all the experiments that are being carried out cannot exclude the possibility that the people participating in them did not go into superficial sleep for short periods of time. This often happens if you do not sleep all night. What happens to the body during superficial sleep? This state is a short break in the work of the brain, which can occur during normal human activities. The internal organs also rest at this time (of course, defectively).
How does chronic lack of sleep affect the body?
ProblemChronic lack of sleep will be considered separately, since in this case a person experiences a daily lack of sleep, although he sleeps for a short period of time. The deficit is gradually accumulating and can result in serious trouble.
Chronic sleep deprivation (typically resting less than 6 hours every day for a week) is equivalent to two days of sleep deprivation. 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, as the result of chronic lack of sleep is insufficient immunity (the number of lymphocytes that fight infections decreases).
Reducing stress resistance also occurs with chronic lack of sleep, this also includes increased irritability and grouchiness. Therefore, if you want to always be a positive and cheerful person, keep a sleep schedule.
Thus, the lack of a night's rest can really become a serious problem for the body. Insomnia will definitely affect a person's he alth. It’s better not to test yourself for strength, not to ask yourself the question: “And if you don’t sleep all night, what will happen?” - but to allocate enough time for regular sleep during the prescribed hours.
