According to the Book of Records
Sleep is already itself
Many of us have at least once wondered how long a person can live without sleep. As is known, night rest The best way restore your strength and recharge your batteries. But what will happen to the body if you don’t sleep for 2 or more days?
A person spends a third of his life on night rest. If we take into account average duration life and subtract 30%, the figure turns out to be impressive. However, without sleep, people cannot live fully. Why? There are several reasons for this:
- during sleep, our body rests, recovers and processes the information received during the day;
- thereby physiological state all systems are restarted;
- work is restored immune system;
- metabolism is normalized.
If a person regularly lacks sleep, in the near future he may have problems with overweight, the work of the heart muscle will be disrupted, it will begin to overcome depressive state, will let everyone know about themselves chronic pathologies and there is a high risk of developing diabetes.
What happens if you don't sleep for a long time
How long can a person last without sleep? As a rule, people can live without a night's rest for up to a week. However, even a day without sleep has a negative impact on your general condition.
Having stayed up late, the body begins to signal that it is time to pay attention to rest, with the following symptoms:
- drowsiness appears first;
- then, absent-mindedness arises;
- further, there is a feeling of heaviness on the eyelids.
Important: If you do not set aside time for rest, a person will soon experience hallucinations. Moreover, several sleepless nights can lead to fainting.
Prolonged wakefulness negatively affects the functioning of organs and systems. A person has sharp jumps Blood pressure, which provokes the development of a number of dangerous pathologies. However, it is enough to lie down and get a good night’s sleep, and the body’s functioning will be completely restored.
Well, now let’s take a look at what’s happening in human body in the absence of rest:
- If a person does not sleep for a day. Lethargy, fatigue and irritability occur. At the same time, blood pressure increases and absent-mindedness is observed. It is worth noting that after the first sleepless night, negative changes are not yet pronounced.
- On the second day, human psyche attacked chemical processes. In this state, information received from the outside is partially assimilated. In addition, the process of destruction of healthy cells begins in the brain, and the load on everything increases. internal systems and organs.
- After three days without sleep, hormonal imbalance occurs. In addition, the production of stress hormone increases, shortness of breath occurs, and the rate of brain cell renewal decreases. Such changes are expressed in memory loss, the appearance of severe depression, and in some cases neurotic disorder, the person begins to get confused in his speech and resembles a madman.
- After four to five days, paranoia develops, speech is impaired, visual and auditory hallucinations. During this period, if human body won't receive good rest, there is a high probability of death.
Important: Scientists have conducted a number of studies and found that due to lack of sleep, the human body reduces its ability to absorb glucose. And this leads to the development of such most dangerous pathology like diabetes.
If after five to six days a person does not die, irreversible processes occur in the body, such as:
- convulsions and tremors appear;
- speech becomes slurred;
- and on last stage the person loses his memory.
Experimenting with night rest is a very dangerous idea and, as you can see from everything described above, it can end fatal. However, there are people who do not sleep of their own free will. This is due to the disease insomnia. This pathology affects about 30% of the entire planet's population. Quite an impressive figure. Moreover, unfortunately, it is only growing every year.
Scientists call the main reason for the development of this disease modern world with its colossal flow of information. Protect yourself from harmful effects You can by following the simplest rules of getting ready for bed.
What if you don’t sleep at all?
Today, medicine knows several facts about people who have gone without sleep for a long time. Usually, similar condition called VSD syndrome — .
This pathology It is transmitted only by heredity and occurs in several dozen families in the world. The disease appears in people aged 30 to 65 years, and lasts from 6 to 36 months, then the person dies.
VSD causes irreversible damage to the brain. It especially negatively affects those departments that are responsible for sleep. Typically, people suffering from fatal insomnia experience the following symptoms:
- panic attacks;
- various phobias;
- hallucinations;
- severe weight loss.
Important: Scientists were able to find out that death occurs not due to insomnia, but due to abnormal brain disorders.
It should be noted that it is not the sleep disorder itself that kills people, but the irreversible brain damage that occurs due to its absence.
Today it is not established exactly how long a person can go without a night's rest. And this is a positive message, given the irreparable harm the condition in question has on the human body. Moreover, the compilers of the Guinness Book also refused to register such dubious records.
Due to what factors can a person go without sleep?
Scientists studying somnology have come to the conclusion that with a long absence of night rest, the human body can become cunning. People cannot stand without sleep for long periods of time.
Therefore, on the third day the brain enters a cycle of superficial rest. In this condition, the hemispheres turn off for short periods of time. Moreover, a person at this moment can be busy with any number of things:
- eat food;
- carry on a conversation;
- commit walking and other.
It is also a proven fact that in extreme cases, people can last longer without rest compared to normal conditions. The reason for this condition is that a person is accompanied by a feeling of danger, which regularly enriches the blood with adrenaline.
In such conditions, the body uses all its capabilities in order to survive. But, as soon as the danger has passed, a person needs a longer rest to restore his strength.
Another interesting fact, in Vietnam there lives a man who has not slept for more than 40 years. This is due to a fever he suffered in childhood. Moreover, according to the doctors observing this patient, he feels cheerful.
Facts about sleep deprivation
How long can you stay awake without dying? And today, despite the intensive development of medicine, doctors cannot give a definite answer. Of course, experiments in this area were carried out, but on rats. And as experiments have shown, the behavior of animals already on the third day became inadequate in relation to their relatives and food.
Well, as for the fatal outcome, the rats died in the second week. Moreover, death was caused by severe weight loss due to which the animal’s body could not maintain normal temperature bodies.
Therefore, scientists came to the following conclusions:
- the likelihood of premature death increases by 15%;
- people with chronic lack of sleep 30% more likely to suffer from depression;
- a week of lack of sleep steals 15% of intelligence;
- a driver who has not had enough sleep for several hours is comparable to a person in medium degree alcohol intoxication;
- lack of sleep negatively affects female and male libido;
- from constant lack of sleep, the thought process is greatly reduced.
But similar negative factors It's only caused by lack of sleep. Now you can imagine how destructive insomnia can be.
And in conclusion, we emphasize that today it has not been established how long a person can actually live without a night’s rest, so as not to harm his health. Of course, many people manage to cut back on sleep. However, it is important to remember that such savings will definitely come back to haunt you in the future. Therefore, devote as much time to sleep as necessary for the body to fully recover.
It's amazing what we spend our time on. According to statistics, over the course of 78 years of life, a person spends a total of 9 years watching TV, 4 years driving a car, 92 days sitting on the toilet and 48 days having sex. But all these numbers pale in comparison to the time spent sleeping. As studies show, A person spends 25 out of 78 years of his life sleeping, which is 32% of his entire life.. You can’t help but wonder: why is sleep so important to us? And how long can we live without it?
Why do you need sleep?
Agree, it would be a shame if we wasted a third of our lives. In fact, the dream fulfills several very important functions . Firstly, it allows our body to rest and process the information received throughout the day. Secondly, as scientists suggest, sleep “restarts” all body systems, and also restores the immune system and normalizes metabolism.
Moreover, lack of sleep, according to doctors, leads to obesity, an increased risk of diabetes, heart problems, depression and other serious ailments.
What happens if you don't sleep for a long time?
When we stay up late, the body reminds us that it’s time to go to bed: we get tired, feel drowsy, absent-minded, heavy in the eyes, short term memory It's getting worse. If we continue to fight sleep for a few more days, our consciousness will begin to become confused, sharp changes moods, paranoia and hallucinations. This condition is well known to truck drivers who spend many hours behind the wheel. People begin to see shadows, non-existent objects, and even simply “pass out” while driving. 
Lack of sleep seriously disrupts the functioning of all body systems. From lack of sleep, a person's blood pressure and the content of stress hormones in the blood is simultaneously disrupted heartbeat and disruptions in the functioning of the immune system begin. As a result, people who do not get enough sleep become irritable and get sick more often. Fortunately, most of these problems disappear after good night.
One way or another, scientists say that the need for sleep is so strong that it outweighs even the feeling of hunger. Eventually, your brain will simply fall asleep, despite all your conscious attempts to fight it.
Is it possible not to sleep at all?
Medicine knows many cases where, over a long period of time, people didn't sleep at all. Such symptoms, for example, occur in patients with a rare genetic disorder called fatal familial insomnia. The disease is inherited and occurs in only 40 families in the world. The disease begins between the ages of 30 and 60 years and lasts from 7 to 36 months, after which the patient dies.
The disease causes serious damage to the brain, in particular to the areas responsible for sleep. Because of this, patients suffer from severe insomnia, panic attacks, phobias and hallucinations. In the last 9 months of life, a person completely stops sleeping and quickly loses weight. Eventually, the patient stops speaking and reacting to his surroundings, after which he dies. Despite its name, fatal familial insomnia does not kill by lack of sleep itself, but by severe brain damage that causes death.
Numerous experiments show that insomnia itself is not fatal, but the reasons that cause it can sometimes kill. 
In the 1980s, scientists at the University of Chicago conducted an experiment on rats. They placed the rodents on special disks above trays of water. When the rat began to doze (this was shown by the encephalogram), the disk rotated, pushing the rodent towards the water, as a result of which it woke up. After a month of this treatment, all the rats died, although the reasons for their death remained unclear. According to scientists, the most likely culprit was the stress of waking up, which the rats experienced about a thousand times a day. It was he who could wear out the systems of their body. Among other symptoms, the rats showed impaired body thermoregulation and weight loss - despite an increase in appetite.
How long can a person go without sleep?
The record of Randy Gardner from San Diego, set in 1964, is often cited as an example of the longest stay awake. As a 17-year-old high school student, Gardner conducted this experiment as an extracurricular science project. According to the scientists who observed him, Gardner did not sleep for 264 hours (a little more than 11 days).
In 2012, a tragic incident that occurred in China received wide publicity. A football fan who had not slept for 11 days, trying not to miss a single game of the European Football Championship, died due to nervous exhaustion.
Science for certain It’s not known how long you can go without sleep. Perhaps this is for the best: given the harm that people do to themselves through such experiences, the compilers of the Guinness Book of Records decided last decade to no longer record achievements in this category.
They got worse. The volunteers first developed auditory and then visual hallucinations. Changed hormonal background, memory deteriorated. Subjects were annoyed bright colors, their speech became slurred, they constantly felt severe weakness.
On the fourth or fifth day of such marathons, brain cells begin to deteriorate, and at this stage the research was stopped, because otherwise irreparable harm could be caused to people.
Participants in the experiment usually spend their sleepless hours in the company of friends. According to their reviews, if their friends did not let them sleep, they would have given up already on the second or third day.
Guinness Book of Records
The Guinness Book of Records contains the names of people who managed to set a record for the number of sleepless nights. The first to be mentioned was the American Randy Gardner. He managed to last 11 days without sleep, but later his figure was surpassed by another American, Robert McDonald. This man’s body turned out to be so resilient that it allowed him to stay awake for 19 days. However, after this, the creators of the book of records refused to introduce new sleepless victories so that people would not expose their health to undue risk.
Neither Gardner nor McDonald's health was seriously harmed. Having slept for 14-15 hours after the experiment, they began to feel normal again.
Obvious-incredible
However, they are also known incredible stories about people who can go without sleep for years. For example, Tai Ngoc, who lives in Vietnam, has this feature. After he suffered from a fever, he began to suffer from insomnia, which has lasted for 38 years. His other compatriot has been awake for slightly less - 27 years. One day Nguyen Van Kha, closing his eyes, felt a strong burning sensation and saw flames. Since then, the Vietnamese has literally never slept a wink.
But the Englishman Eustace Burnett did not have any pathologies. One evening he simply realized that, despite the late hour, he did not want to sleep. And since then, for 56 years, while his household dreams, he, according to him, solves crossword puzzles.
There is a firm belief that a person cannot live without air, water, food and sleep. Every year more and more experiments are being conducted to determine whether existence is really impossible without these conditions. It has been proven that, on average, you can last about one and a half minutes without air, about 5 days without water, and no more than two months without food. And every person can do without sleep different time.
What is sleep for?
The human body is designed in such a way that it requires a constant change of wakefulness and sleep cycles. Almost a third of your life is spent sleeping. Sleep is essential for recovery vitality and energy. Insomnia is painful for any living organism. Also in ancient China There was a penalty for insomnia. The human body was brought to complete exhaustion, without giving it rest.
Sleep is a key indicator of mental health. A person who has the opportunity to sleep 7-8 hours a day is a full-fledged member of society. People who are sleep deprived or sleeping large quantity hours tend to feel sluggish and unfocused. Just imagine, alone a sleepless night reduces performance by 30%, two in a row by 60%. Five or more sleepless people can significantly undermine mental health.
Scientific experiments or “waking volunteers”
In 1965, schoolboy Randy Gardner set a record by going 11 days without sleep. The first day I felt quite natural. A couple of days later he started having headaches. The first signs of Alzheimer's disease, that is, memory loss, also began to appear. Towards the end of the experiment, the student began to experience hand tremors and hallucinations. He could not concentrate or perform even the simplest tasks. The experiment was stopped.
Later, according to unconfirmed sources, a certain man set a period of 28 days without sleep.
The world record for the time spent without sleep belongs to a certain Robert McDonald, who did without rest and without special stimulants for 18 days and 21 hours. However, scientists have found that this case rather an exception from general rules, since the average period without sleep and particular harm to health is only 3-5 days.
Of course it is impossible. In a few days it starts irreversible change general hormonal background. After 5-7 days, brain cells, unable to withstand the load, begin to break down, which can lead to irreversible consequences.
Scientists say that under severe overload, the body is capable of so-called “shallow sleep,” that is, a person seems to be awake and doing his job, but part of the brain at the same time gives itself the opportunity to rest.
Of course, experiments with insomnia are extremely dangerous, and you should not tempt your body with attempts to set a record. For full life And good health Be sure to give yourself rest and normal sleep.
People spend about a third of their lives sleeping. It is as necessary for life as breathing, water and food. Being deprived of proper sleep for a long time, a person begins to experience health problems.
Record breakers
In 1964, a young man named Randy Gardner from San Diego participated in an experiment and did not sleep for 11 days, as a result of which he was included in the Guinness Book of Records. At first he felt tired and irritable, and on the sixth day he began to show signs of Alzheimer's disease, then hallucinations and tremors in speech, and forgetfulness.
This record was later broken by 42-year-old Briton Tony Wright, who also stayed awake for 11 days, but several hours longer than Randy Gardner. During this time, he ate only fruits and vegetables, drank infusions, played billiards and kept a diary. Tony was never included in the Guinness Book, since the category of sleep deprivation was excluded by the administration from the book due to its detrimental effects on health.
There are cases of much longer wakefulness, but these are mainly people with certain exceptional features. An ordinary person, on average, is able to go without sleep for 3-5 days at the cost of very great effort.
What matters here is individual characteristics person. Some people need up to 12 hours a day for rest and recovery, while for others 4 hours of sleep is enough (as was enough, for example, for Napoleon and several others). historical figures). Some people may remain active longer, others less. There is an opinion that the need for sleep is influenced by the strength and power of a person’s energy, his biofield, which some devices can even record.
Consequences of lack of sleep
It happens that people do not sleep for several days, working on an urgent project, being in extreme situation or in war.
In any case, unless necessary, it is better not to test the capabilities of your body and provide it with good sleep. After regular and prolonged lack of sleep, it is difficult for the body to recover. The consequences of this are dizziness, slow reactions, confused speech, digestive disorders, decreased visual acuity, problems with the nervous system, depression, accelerated aging, decreased mental and physical abilities, etc.
Scientists have found that one sleepless night reduces a person’s cognitive functions by 30%, two nights - by 60%. Then the hormonal background begins to change, the connections between neurons in the cerebral cortex, and the psyche suffers. The longer you stay awake, the more problems arises. After three to five days without sleep, brain cells begin to deteriorate, and the load on the heart and the entire body increases. Further sleep deprivation is fraught with irreversible complications and even death.
Many probably remember Sydney Pollack's film "They Shoot Horses, Don't They?" V leading role with Jane Fonda. It was about a dance marathon, the participants of which had to long time spend without sleep. Significant expectations awaited the winners money prize. But it turns out that such competitions were actually held.
22 weeks
During the Great Depression (1929-1933) in the United States, such marathons were very popular. The dancers were instructed to move to the music as long as possible. The last pair of participants able to hold on won about $3,000. At first glance, this is not a very difficult test. But - only for the first one. The longest dance marathon lasted more than 22 weeks. However, however, one of the partners was allowed to doze off from time to time, and the second was allowed to support the dozed off one.
Furry caterpillar costume
But in 1959, 32-year-old New York showman Peter Tripp announced on the radio that he would not sleep for 8 days and 8 hours. Some doctors and psychologists decided to study how prolonged wakefulness affects human health. During the experiment, Tripp was in a glass booth in Times Square, and the assembled “onlookers” could watch what was happening.
At first Tripp was cheerful and joked, but on the third day he complained of fatigue. Then he suddenly began brushing non-existent cobwebs off his shoes. After 100 hours, Tripp suddenly announced that the costume of one of the spectators was made from furry caterpillars.
After 120 hours, the showman began to have visual hallucinations, then he thought that someone wanted to poison him. Soon he could no longer cope with the simplest tests offered to him by doctors. For example, he could not name the alphabet. And at the end of the marathon, a completely exhausted Tripp refused to cooperate with the doctors at all, since, in his opinion, they were “weaving” around him.
Marathon of Wakefulness
After all, Peter Tripp set a world record by going 201 hours without sleep. Thanks to him, scientists have established that the patterns of brain functioning during such prolonged wakefulness resemble those observed when a person sleeps. It is worth noting that this experiment cannot be considered “pure”. After all, Tripp took stimulants and drank coffee to stay awake.
After completing his “wake marathon,” Tripp slept for 13 hours and 13 minutes. most of sleep fell on fast phase(sleep phase characterized by increased activity brain). Scientists have concluded that if people are woken up when this phase begins, they may experience nervous breakdowns and even hallucinations may occur, and the dream itself is something like a safety valve for our consciousness. If this valve is not “opened” from time to time, one will become mentally unstable or even fall into madness.
The question of how long a person can go without sleep interests people, how can they scientific point sight and out of curiosity. It was experimentally established that every day a person needs to spend 6-8 hours in a state of sleep in order to be able to recover from energy expenditure during the day. Sleep deficiency or lack of sleep can lead to changes in cognitive and emotional sphere people, contribute to changes in physical level, which manifests itself in the occurrence of various psychomatic diseases.
However, there are individuals in the world who are able to go without sleep for a long time. This is mainly due to mental disorders And genetic mutations when there is a change in biochemical processes in the brain and a violation of neuroregulation.
But there are also individuals who consciously choose to refuse sleep due to their personal motives, which are based on entertainment, self-knowledge, or stupefying the mind akin to drugs. Sleep deprivation techniques are also deliberately used to stage hallucinations, to heighten sensory capabilities and a sense of unreality. It was these initiators that served as an incentive for neurophysiologists to conduct experiments and find answers to the questions: how long a person can stand without sleep.
One of the first such daredevils who decided to demonstrate to themselves and others how long a person can go without sleep was an ordinary American schoolboy, Randy Gardner. He was able to set a scientifically and documented record of maximum stay in a state of wakefulness, without the use of any stimulants.

In the fall of 1963, 17-year-old Randy decided to stay awake as long as physically possible. And he succeeded! He was able to stay awake for 11 consecutive days, for a total of 264.30 hours.
The record was recorded by the Commissioner for Dreams at Stanford University, Dr. K. Dement. Randy could have continued to set the record, however, John J. Ross, the colonel of military medicine who monitored his health, was strictly forbidden to do so, due to negative consequences related to physical and psychological state young man.
With his experiment, the guy proved that when a person is deprived of sleep for a long time, there is Great chance destructive changes in the intellectual, sensory, and psychological components human brain. At the end of the experiment, Randy Gardner was depressed, had memory problems, and hallucinated. However, the teenager's physiological health remained in order; he was confidently able to beat his opponent in pinball after 11 days spent without sleep.
Experiments to study how long you can stay awake without harm did not stop there. They aroused genuine interest, in particular, the question arose: what consequences can arise when a person is deprived of sleep for a long time? Can lack of sleep lead to death? And where is the line that makes it clear: how long can you live without sleep in days?
A series of experiments began on people in order to understand how long a person can stay awake.
So, in 1986, researchers from the United States studied a group of volunteers consisting of 3 people who were not supposed to sleep for 90 hours. Oddly enough, despite the difficulties, they managed to overcome sleep by the third day without causing harm to their health. Based on this, the researchers concluded: a one-time deprivation of a person’s sleep for 2-3 days does not cause him any physical or moral harm.
Lack of sleep and consequences
In the course of studies conducted by neurosurgeons, psychiatrists and physiologists, a cause-and-effect relationship was established: /deviation. They gave a description of what happens in the body of a person who is somehow deprived of sleep. The main starting points for the changes taking place were: 24, 48 and 72 hours.
24 hours
If you don’t sleep for a day, your body won’t experience any special consequences. The next day, a person may only feel some fatigue, inattention, and decreased intelligence. Cognitive impairments similar to alcohol intoxication occur.
48 hours
After this time without sleep, the body turns on a compensatory function: it begins to accumulate energy through microsleep. These are periods of 1-30 seconds. In this state, a person feels mild disorientation. Moreover, this state occurs suddenly, regardless of the circumstances. After 48 hours without sleep, focus is lost and the person is unable to retain information in short-term memory.
72 hours
This time without sleep leads to disruption mental processes: perception, memory, thinking, imagination. Hallucinations predominate, speech is distorted. Sensory abilities are lost.
Staying without sleep for longer periods of time leads to serious consequences – structural changes personality, distortion of perception, psychosis and changes in neuroregulation in nervous system– and as a result, to psychosomatic diseases.
