How many people can not sleep, not eat and not breathe?

Sleep, food, breathing - all this is perfectnatural things that are simply necessary for the normal operation of the human body. But sometimes it becomes interesting: how many people can not sleep or, for example, not eat? After all, the body has its own limits.

How many people can not sleep?

To begin with it is worth noting that the normala healthy sleep is very important not only for the human psyche, but for the normal functioning of the whole organism. At night, the work of all organs slows down, thus recovering. In addition, sleep is the period of the subconscious work, when everything seen, heard and thought over the day is somehow classified. The subconscious actively searches for answers to questions, makes some conclusions from the information received, etc.

But how many people can not sleep? First of all, it should be noted that even if the individual does not drink more than two days, his body can not be called normal, since all organ systems, including the brain, work literally at the limit.

The first record was set by Tony Wright in 1965,who managed to hold out without sleep for 11 days. Of course, this was done intentionally, from the desire to get into the Guinness Book of Records. Fortunately, a few years later the committee ruled out the category of this peculiar "insomnia" from the list of records, not without reason asserting that such experiments are too dangerous for life. Of course, history knows a lot of interesting facts. For example, Maureen Weston did not sleep for 18.5 days without taking any medication. There are also data about certain special people who, as a result of trauma or clinical death, no longer sleep at all, or at least their brain rests not in the same way as usual. There is even a genetic disease - a family insomnia syndrome, when people simply can not fall asleep. But these are exceptions. Such feats are beyond the strength of an ordinary, average person.

A few days without sleep can lead toirreversible changes in the body or even death. For example, on the second day there is an increase in the level of hormones in the blood. At about this time, neural connections in the cerebral cortex slowly begin to degenerate. Of course, people do not notice this. The only symptom is lethargy, a feeling of intoxication, increased mental activity. Starting from 4-5 days, nerve cells slowly break down in the brain, which it is almost impossible to restore.

As a rule, at this time a person begins to run intoin the so-called fast, superficial phase of sleep. It can last only a few seconds, but the body of this time is enough to at least somehow support life. But "fast" sleep is dangerous for the individual. The fact is that he can not be controlled - a person does not even suspect that he fell asleep for a second. And if at this time you drive a car? In short, the lack of sleep is a very dangerous condition.

How many people can not eat or drink?

Nutrition is another important part of ourexistence. Scientists believe that a normal, average person can live without food on average two months (sometimes this figure reaches 8), but only if he consumes a sufficient amount of liquid.

As for drinking, the body canexist without fluid intake no more than 5-7 days. After this, the most severe stage of dehydration occurs, leading to a fatal outcome. Death from hunger and thirst is a very difficult, painful and painful process.

How many people can not breathe?

Another interesting question. Now you know how many people can not sleep and not eat. But how much the body will last without air? Of course, we can not deliberately break the breath for any time - after 2-3 minutes the respiratory reflex enters into force. Therefore, conditions in which air is absent are considered here. If insomnia, starvation, dehydration can last for months, then the bill goes on for minutes. On average, a person can be without oxygen for no more than 5 minutes. Then acute cerebral hypoxia begins, after which the nerve tissues irreversibly change. Even there is to return the person "from the other world," part of his brain will be damaged.
