It can last for about three days at most, and if you don't sleep after three days, it may cause serious effects on your body.

Medical studies have shown that humans can normally stick to 3 to 4 days without sleeping, but not sleeping for a long time will lead to a decrease in people's immunity and a state of dizziness and anemia, so no matter how busy you are at work, you still have to take proper rest.

Three days, because people become very tired during three days, it is basically a state of scrapping, which is more terrible.

Objectively speaking, at this time, I remembered an experiment I had read in the newspaper that Russia had done, the content of the experiment was to let some prisoners, in a closed room, tell them that as long as they can hold out to the end, they can be acquitted, during this period, others will provide food and water for the people in the room for free, and even some leisure tools, but the only requirement is that they cannot be allowed to sleep, remember that the person who lasted the longest in this experiment was 7 daysThat is to say, if we don't sleep all the time when we have sufficient material security for other lives, we can hold on to 7 days at most, but this is only a theoretical value, and I believe that ordinary people can't stick to this pointAnd there are many disadvantages of not sleeping, specifically the following:

1. Endocrine disorders

People who often don't sleep will first make our endocrine disorders in our body, because when sleeping, our body will automatically regulate the endocrine in the body according to the body values after we rest, so that our endocrine can achieve a balanced effect, if we don't sleep, then the body will lose the opportunity for this regulation, and it will also make us endocrine disorders.

2. Frequent hair loss

Due to endocrine disorders, it can cause our scalp to produce oil frequently, the rate of metabolism decreases, which leads to hair loss, and if the rate of hair loss exceeds the rate of biochemistry, then in the long run, we will even go bald.

3. Neurasthenia

If we don't sleep for a long time, our nerves will not be rested, so that we will become nervous breakdown, unable to concentrate, have no energy to maintain normal work or study, and become more and more sensitive mentally, and in the long run, it may also bring us psychological damage.

The average person does not sleep all the time, and can last for about seven days at most. At present, the one who can insist on not sleeping for the longest time is an Englishman, who holds the highest record of not sleeping for 11 consecutive days, but this Englishman is professional, and after a series of training, he is specially here to challenge the world record, and he is already in an unconscious state in the later stage, so ordinary people cannot compare with him.

People can't do without sleepThe biggest characteristic of us as human beings is that we have to sleep and rest every day, and we spend about 1 3 hours in sleep in our lives. And at least 5 hours of sleep should be maintained in a day, otherwise it will affect the health of the body, and if you lack sleep for a long time, you will be prone to physical weakness and lack of energy, resulting in a decline in physical ability. It can be seen how important sleep is to human health, according to scientists' experiments, people can survive for 20 days without eating when there is water to drink, and they can survive for 7 days without drinking water, but if they don't sleep continuously, the average person can only hold on for 5 days, and people with good physique can only last about six or seven days.

Lack of sleep will destroy healthSerious lack of sleep will have a great impact on the human body's nerves and resistance, immunity system, and the mental pressure on people is also considerable, people who do not sleep continuously from the 3rd day, the mood has reached the limit of endurance, become quite irritable, easy to attack others, people with poor psychological quality will collapse and become nervous. In addition, the biological clock disorder caused by not sleeping for a long time will also cause endocrine disorders, frequent hair loss, and human health will also be destroyed, so that the body will linger in a sub-healthy state for a long time.

In addition, not sleeping for a long time will also make the nerves unable to rest, resulting in inability to concentrate and focus, that is, neurasthenia. People who are not in good health, due to the long-term operation of various organs of the body can not rest and recover, it is also easy to cause the phenomenon of sudden cessation of work of body organs, that is, sudden death. Sudden death caused by lack of sleep is more common in people with neurasthenia, high blood pressure or cardiovascular and cerebrovascular diseases, so it is best for people with physical diseases not to stay up late and try to maintain normal sleep and regular life.

Personally, one day is the limit, generally I can fall asleep when I get a chair until two or three o'clock at night, it's not a matter of a few days, it's a problem of not staying up all night.

The Guinness Book of World Records is held for 11 days, and it is better for the average person not to try this practice, as not sleeping for a long time can permanently damage the nerves in the brain.

It certainly won't last long, and it's a terrible thing to not sleep for a long time, and people can go crazy.

Three days and three nights should be dying! At that time, it is not a question of whether you can hold on, even if you have the heart to persevere, but your body does not allow it.

For three days at most, if you don't sleep, the organs will not be able to stand it, and to a certain extent, you will die suddenly, so you still have to sleep well.

Not sleeping for long periods of time can damage the brain and cause shock. If you don't sleep for 72 hours, you will be very weak and even die of shock.

Personally, I have to sleep when the time comes, otherwise I will not have the energy and I will not be able to concentrate on things. No more than 18 hours without sleep.

Sleep accounts for almost 1 3 of our time in our day, and sleep is very important for the human body. Sleep can not only improve the body's immunity, but also allow the body to get enough rest time from the brain to the muscles. In today's fast-paced world, many people can't get enough sleep, or even don't have time to sleep.

So how long can a person last without sleeping? And how long in a day is the healthiest time of day? <>

First of all, how long can a person go without sleep, and this is a question that a man in England has challenged before. He once challenged to go without sleep for 11 days in a row, but since then he has been suffering from various physical problems, and his physical condition is not as good as before. But there are medical studies that show that after three days of not sleeping, the human body will start to have problems.

If humans don't sleep all the time, the organs in the body will work all the time and will not wait for rest. Even if it is a factory machine, it has to take regular breaks, otherwise there will be a breakdown. If you don't sleep all the time, all aspects of your body, such as mental strength and concentration, will decrease, and the whole person's state will deteriorate visibly.

And during the day, it becomes muddy, confused, and his emotional state is also very fluctuating. All aspects of the body's functions seem to show that this person has begun to do something wrong. Therefore, people should have a good rest and maintain a sufficient sleep during the rest time, so that they will have the energy to do a good job the next day.

Second, how long a person sleeps in a day is the healthiest. One of the most popular folk sayings is 8 hours, but in fact, this is not the case, people of different ages have different requirements for sleep, generally speaking, babies sleep the longest, and children, adults, and the elderly sleep time is different. And everyone's physical condition is different, so you should set a reasonable sleep time according to your physical condition.

Sleep quality is not a trivial matter, and not sleeping well can seriously affect a person's body and work. Sleep well and keep enough energy to do what you want to do.

If you don't sleep for three days, you will have some problems with your eyesight and hearing, and your body will change a lot. It is healthy for adults to sleep about 8 hours a day, so that they can get better rest.

I think people can go up to 5 days without sleeping, but it will cause relatively much damage to the body and will become exhausted; Sleeping 8 hours a day is the healthiest way to get your body back to normal.

It is possible to insist on not sleeping for a week or so, and if it exceeds a week, there is a high risk of sudden death. Sleeping about 8 hours a day is the healthiest way to relieve fatigue without harming the body.

This is because people need to rest, and after sleeping, they can buffer the brain and the body. If you don't sleep, you can do it for about 3 days.

In order to get a better rest, if you don't sleep, you can stick to it for up to 3 to 5 days, otherwise you will feel very uncomfortable and very tired.

Sleep in order to allow the organs and cells of a busy day to fully rest, and the machine needs to rest a property, otherwise it will be scrapped if it has been used.

It is difficult to say that there is any exact number of days, according to each person's physique, nutritional status, activity or not or the "intensity" of the activity and other aspects are related, under normal circumstances, it is about three days, very few may be longer;

If a person does not sleep for a long time, first of all, the person has no energy, and then there will be a decrease in appetite, a decrease in body coordination, or an obvious reduction in reaction ability, and a series of "fatigue" symptoms in the body, and then the body's endocrine, electrolyte balance, etc. will be affected and changed, then the human body will have some symptoms of disease rather than just fatigue; If you don't analyze whether people can "persevere" (assuming that you can stay awake all the time) and only talk about the impact on the body, it will definitely cause diseases to occur over time, and may even cause some organs of the body to appear similar to "failure", then if this is the case, it may be life-threatening.
