Everyone, probably, at least once in their life, but one night did not sleep. Whether it was due to night parties that smoothly transition into the next day or preparation for the session, or was it a work necessity - usually, if possible, a person, if he has not slept all day, tries to catch up on the next night. But there are times when it is not possible to sleep 2 days in a row or even 3 days. Emergencies at work, time trouble at the session and you have to not sleep for 2-3 days. What happens if you don't sleep for a long time?

Sleep is the rest of the body, it is responsible for processing and storing information, restores immunity. Previously, lack of sleep was used as a torture to extort secrets. However, recently, experts submitted a report to the US Senate that such testimony cannot be trusted, because in the absence of sleep, people hallucinate and sign false confessions.

If you do not sleep for 1 day, nothing terrible will happen. A single violation of the regime of the day will not lead to any serious consequences, unless of course you decide to spend the next day behind the wheel. It all depends on individual features organism. For example, if a person is used to such a work schedule, when after the night shift there is still work during the day, then he will simply finish these hours the next night.

During the next after sleepless night day, a person will feel drowsiness, which can be slightly relieved with a cup of coffee, fatigue, a slight deterioration in concentration and memory. Some feel a little chill. A person may suddenly fall asleep in public transport, sitting in line to the doctor, for example. The next night, there may be difficulty falling asleep, this is due to an excess of dopamine in the blood, but the sleep will be strong.

One thing is certain if you're wondering something like: what if you stay up all night the eve of your exam? There is only one answer - nothing good. A sleepless night does not contribute to the readiness of the brain for stress. The thought process, on the contrary, will become slower, intellectual abilities will decrease. Distractedness and inattention are companions sleepy state. Of course, a person will look worse - the skin will gray color, there will be bags under the eyes, some puffiness of the cheeks.

Experts note that it is enough to skip only the first 24 hours of sleep and violations begin. brain activity. German researchers noted the appearance of symptoms mild schizophrenia: distorted sense of time, sensitivity to light, incorrect color perception, incoherent speech. The emotional background begins to change; how longer man does not sleep - the more exaggerated emotions become, laughter is replaced by causeless sobs.

If you don't sleep for 2 nights in a row

Of course, situations may arise when you have to stay awake for 2 days in a row. This is a more difficult condition for the body, which can affect the work of internal organs and it will manifest itself not only in drowsiness, but also in the malfunction of the work, for example, of the gastrointestinal tract. From heartburn to diarrhea - the range of sensations experienced can be very diverse. At the same time, the person's appetite will increase ( obvious advantage will be given salty and fatty foods) and the body, in response to stress, will start the function of producing hormones responsible for insomnia. Oddly enough, during this period, it will not be easy for a person to fall asleep, even with a strong desire.
After 2 sleepless nights in the body, glucose metabolism is disturbed, work worsens immune system. The person becomes more open to the effects of viruses.

After two sleepless nights strong man will become:

• scattered;
• inattentive;
• his concentration will deteriorate;
• intellectual abilities will decrease;
• speech will become more primitive;
• coordination of movements will worsen.

If you don't sleep for 3 days

What happens if you don't sleep all night for 3 days in a row? The main sensations will be the same as after two sleepless days. Coordination of movements will be disturbed, speech will worsen, it may appear nervous tick. This condition is characterized by loss of appetite and mild nausea. The experimenter will have to constantly wrap himself up - he will have a chill, his hands will become cold. There may be such a state when the gaze is focused on a particular point and it becomes difficult to look away.

It must be said that under conditions of prolonged inability to sleep, a person begins to experience states of failure - when he turns off for a while and then comes to his senses again. Is not superficial sleep, a person simply turns off the controlling parts of the brain. For example, he may not notice how he missed 3-5 stations in the subway, or when walking down the street, he may not remember how he passed the section of the path. Or suddenly completely forget about the purpose of the trip.

If you don't sleep for 4 days

What will remain of the human brain if you do not sleep for 4 days is not clear. After all, if you don’t sleep for a day, the ability to process information is already reduced by a third, two days of being awake will take 60% of a person’s mental abilities. After 4 days no sleep on mental capacity a person, even if he is 7 spans in the forehead, cannot be counted, consciousness begins to get confused, strong irritability appears. Plus, there is a trembling of the limbs, a feeling of waddedness of the body, and it worsens greatly. appearance. The person becomes like an old man.

If you don't sleep for 5 days

If you don’t sleep for 5 days, hallucinations and paranoia will come to visit. Possibly start panic attacks- the most nonsense can serve as an occasion. Appears during panic attacks cold sweat increased sweating, increased heartbeat. After 5 days without sleep, the work of important parts of the brain slows down, and neural activity weakens.

Serious violations will occur in the parietal zone, which is responsible for mathematical abilities and logic, so a person will hardly be able to add even 2 plus 2. In this situation, it is not at all surprising that if you do not sleep for so long, there will be problems with speech. Violations in the temporal lobe will provoke its incoherence, and hallucinations will begin to occur after the malfunction of the prefrontal cortex of the brain. These may be visual hallucinations similar to dreams or sound.

If you do not sleep for 6-7 days

Few people are capable of such an extreme experiment with their body. So, let's see what happens if you don't sleep for 7 days. The person will become very strange and give the impression of a drug addict. It will be impossible to communicate with him. Some people who decided on this experiment developed Alzheimer's disease syndromes, severe hallucinations, and paranoid manifestations. The record holder for insomnia, a student from America, Randy Gardner, had a strong trembling of the limbs and he could not even perform the simplest addition of numbers: he simply forgot the task.

After 5 days without sleep, the body will experience the strongest stress of all systems., brain neurons become inactive, the heart muscle wears out, which manifests itself painful sensations, immunity due to the passivity of T-lymphocytes ceases to resist viruses, the liver also begins to experience enormous stress.

Oddly enough, after long-term condition no sleep, all symptoms will disappear literally after the first 8 hours of sleep. That is, a person can oversleep for 24 hours after a long wakefulness, but even if he is awakened after 8 hours, the body will almost completely restore its functions. This, of course, is the case if the experiments with sleep are one-time. If you constantly force your body, not letting it rest for two or three days, then it will end with a whole bunch of diseases, including cardiovascular and hormonal systems, gastrointestinal tract and, of course, psychiatric plan.

If a person is deprived of sleep for 7 days, then starting from the 5th day high risk die from lack of sleep - for example, from heart attack due to hallucinations. This is how a person works - we need to recuperate after day labor. During sleep, the subconscious is actively involved in the work, the information accumulated during the day is processed. The muscles of the body are resting internal organs calmly busy with their functioning, consciousness is turned off. Why is it so important to go to bed at the right time, get enough sleep, and never deprive yourself of sleep for a long time? This is easy to understand if you follow what happens to a person suffering from insomnia different reasons. The consequences are dire...

1st day
1 day without sleep is not much. Surely you will remember a situation when you did not have to go to bed for a whole day. Fatigue, bad memory and concentration, wandering attention, headache, indigestion - that's what is usually observed after a sleepless night. Memory and attention cannot function normally due to the fact that neocortex did not recover overnight. All systems in the body are connected, and therefore other organs react to lack of sleep. For health, 1 day cannot cause significant damage, but well-being is unpleasant.

2nd–3rd day
Violated not only attention, but also coordination of movements. frontal lobes brain cannot work normally without proper rest, because creative thinking you can forget. A person left without sleep for 3 days is in a state of nervous exhaustion. There may be a nervous tic, panic attacks. Appetite will increase, because in stress the body will release a large number of the hormone cortisol, which promotes unrestrained eating. I want fried, salty, spicy, and this despite the fact that digestive system works poorly and unsystematically. Falling asleep, oddly enough, is very difficult - again due to overwork nervous system.

4th–5th day
Hallucinations are bound to come. A person will speak incoherently, poorly understand what is happening to him, solving the simplest problems will become unbearable for him. At the same time, irritability and anger will increase in proportion to the time spent without sleep. Parietal and prefrontal cortex will refuse to work, that's why all this is happening.

6th–7th day
American student Randy Gardner did not sleep for 11 days. Already on the 7th day, he behaved extremely strangely, experiencing the strongest hallucinations and showing symptoms of Alzheimer's disease. The tremor of the limbs, the inability to think sensibly and the strongest paranoia are what he had to endure for the sake of a scientific experiment.

Among the causes of insomnia are nervous and muscle tension, pain syndrome and indigestion. Stuffiness, bright light, uncomfortable bed - that's what makes it difficult to fall asleep. Insomnia itself is considered the cause of many diseases, doctors say: if you want to recover, first get rid of insomnia. But it happens that a person does not sleep for several days on his own initiative - this may be due to work. In doing so, you must be aware of the consequences of failure in the normal mode of life. It is recommended to sleep at night, and not during the day, because in complete darkness the human body produces hormone melatonin. Melatonin prolongs youth, improves brain function, protects a person from oncological diseases. Sleep is a medicine that everyone needs.

Surely many of you have experienced a situation where you had to stay awake at night. For example, it may be the night before the session, unlearned school homework. And someone needs to go to work, because the night shift is scheduled. Therefore, the question of what will happen if you do not sleep for 2 days is quite relevant. Let's try to deal with this problem.

Consequences of two nights spent without sleep

With a person there are different, most unpredictable situations.

• general, depressed state of health;
• the strongest lethargy;
• disorders of the stomach (diarrhea or constipation);
• increased appetite, and you want salty, spicy foods;
• a state close to stress;
• Weakening of the immune system, making it harder for the body to fight viruses
• distraction, inability to accept fast decision if nessesary;
• blurred vision (difficulty focusing on a particular subject);
• it is difficult to concentrate on any thought;
• speech becomes simplified;
• problems with coordination of movements;
• headaches in combination with noises;
• jumps in blood pressure;
• muscle and joint pain;
• increased heart rate;
• uncontrolled irritability.

If you do not sleep for two days, then the body will begin to produce certain hormones to deal with a stressful situation. After a sleepless pastime, I really want to fall asleep. But, the longer you stay awake, the harder it is to get out of the state of wakefulness.

It is known that under certain emergency situations, the reserve buttons of the body are turned on, increased activity occurs.

This is not available to civilians. Only the military. Each country has its own battle cocktails. If you buy Modafinil (Alertec) from Europeans, you can stay awake for two or three days without any negative feelings. But, do not forget that the main thing for the military is efficiency during the battle and service. How a person will continue to live there, whether there will be any serious consequences - they do not care.
The Saudis are feeding Syrian rebels with amphetamine-based pills. You don’t sleep there either, but it blows your mind) Drugs, after all.

So it's better to sleep for at least an hour or two. The body cannot do without sleep. To restore strength, the body produces melatonin, the sleep hormone. It can be bought at a pharmacy without a prescription. You drink, you fall asleep, you just need to internally tune in that you only sleep for two hours and ask someone to wake you up) With melatonin, sleep is very strong. When you tune in, the body knows that it doesn’t have much time, it won’t go into a prolonged phase of sleep. And if you cross - then you can be dragged, the person "dies" there, so you want to sleep at the moment of waking up)
After waking up, contrast scent and make a civilian "combat cocktail") This is a mixture of various invigorating alkaloids and mint.
Mint is needed so that there is no nervous tremor and the heart does not beat too hard.
Those. you take a teaspoon of coffee, a teaspoon green tea, two teaspoons of cocoa, a pinch of dry mint or a bag mint tea, a little sage if there is (good for the brain), you brew everything, insist, filter and drink. The taste is peculiar, but not nasty) It invigorates well, the head becomes fresh, better than just coffee.
So that you do not want to sleep for a long time - buy a tincture of Rhodiola rosea in a pharmacy. Ch. Spoon inside and do not want to sleep. unaccustomed to it, you can freak out.
This is a set for a fighting cocktail) You can also add alkaloids of chocolate or Coca-Cola.

I have a lot of experience sleeping for several hours. I tell from practice) But in this mode it is necessary to nourish the body very well. Vitamins, honey, fruits, figs for the head and dried apricots for the heart (the heart is the first to suffer from lack of sleep), sea ​​kale. raw eggs, is a storehouse of amino acids and useful substances.

After such overloads, you need to rest twice as much. Those. one night you do not sleep - then you need to sleep for two nights in a row. Three nights for 3-4 hours - you also need to sleep off a couple of days.

I stay like this for 4-5 days! but then the head counts 2 + 2 for 5 minutes! so be careful!

On weekends, many people not only do not get enough sleep, but almost do not sleep, leaving for a sleepless two-day entertainment marathon. We decided to find out what would happen if we didn't sleep for a week.

First day

If a person does not sleep for a day, then no serious consequences for his health, this will not cause, however long period wakefulness will disrupt the circadian cycle, which is determined by the setting biological clock person.

Scientists believe that for biological rhythms body respond approximately 20,000 neurons in the hypothalamus. This is the so-called suprachiasmatic nucleus.

Circadian rhythms are synchronized with the 24-hour light cycle of day and night and are associated with brain activity and metabolism, so even a daily delay in sleep will lead to minor violation in the functioning of body systems.

If a person does not sleep for a day, then, firstly, he will feel tired, and secondly, he may have problems with memory and attention. This is due to a violation of the functions of the neocortex, which is responsible for memory and learning abilities.

Second-third days

If a person does not go to bed for two or three days, then in addition to fatigue and memory problems, he will add a violation of coordination in movements, they will begin to appear serious problems with concentration of thought and concentration of sight. Due to the exhaustion of the nervous system, a nervous tic may appear.

Due to a disruption in the work of the frontal lobe of the brain, a person will begin to lose the ability to think creatively and focus on the task, his speech will become monotonous, clichéd.

In addition to "brain" complications, a person's digestive system will also begin to "rebel". This is due to the fact that a long period of wakefulness activates the protective evolutionary mechanism "fight or flight" in the body.

A person will increase the production of leptin and increase appetite (with an addiction to salty and fatty foods), the body, in response to stressful situation, will start the function of storing fats and producing hormones responsible for insomnia. Oddly enough, it will not be easy for a person to fall asleep during this period, even if he wants to.

Fourth-fifth day

On the fourth or fifth day without sleep, a person may begin to experience hallucinations, he will become extremely irritable. After five days without sleep, the work of the main parts of the brain will slow down in a person, neural activity will be extremely weak.

Serious violations will be observed in the parietal zone, which is responsible for logic and mathematical abilities, so solving even the simplest arithmetic problems will be an impossible task for a person.

Due to disturbances in the temporal lobe, which is responsible for speech abilities, a person’s speech will become even more incoherent than on the third day without sleep.

The hallucinations already mentioned will begin to occur due to a malfunction in the prefrontal cortex of the brain.

Sixth to seventh days

On the sixth or seventh day without sleep, a person will not be much like himself at the beginning of this sleepless marathon. His behavior will be extremely strange, hallucinations will be both visual and auditory.

The official record holder for insomnia, American student Randy Gardner (did not sleep for 254 hours, 11 days), on the sixth day without sleep, developed syndromes typical of Alzheimer's disease, had severe hallucinations and appeared paranoid.

He took road sign for a man and believed that the radio station host wanted to kill him.

Gardner had a strong tremor of the limbs, he could not speak coherently, the decision simple tasks baffled him - he simply forgot what he had just been told and what the task was.

By the seventh day without sleep, the body will experience serious stress of all body systems, brain neurons will be inactive, the heart muscle will be worn out, immunity will almost cease to resist viruses and bacteria due to the inactivity of T-lymphocytes, the liver will experience enormous stress.

In general, such experiments with health are extremely dangerous.
