What will happen if you do not sleep?

Surely everyone happened, and more than once, to stay awake for a whole day, or even two: a session, a naughty baby, urgent work, daily duty, party games until the morning. And it happens that just do not fall asleep, and tomorrow to work.

Well, if you do not sleep for several days, how will this affect your condition and health?

The first day without sleep

Such a failure of the regime does not pose a particular health hazard. Of course, after a sleepless night you are unlikely to stay awake and ready for feats, and you will not look very much – a gray face, red eyes, and bags under them. In addition, you may shiver a little.

You can cheer up a cup of coffee, but still by the middle of the next day you will want to sleep and can doze off right behind the desk. Yes, and the employee of you will not be so hot – distracted, inattentive. Well, if you have an exam, then be prepared for the fact that it will be difficult to concentrate on the question.

And the next night, you may not fall asleep immediately. But you will sleep soundly.

Two days without sleep
This is a more serious test for the body. Along with absent-mindedness, difficulties with concentration, drowsiness, reduced intellectual abilities (and two sleepless nights reduce intellectual activity in a row by 60%), coordination of movements is disturbed, and the vocabulary becomes poorer.

Absent-mindedness, fatigue
There are violations in the work of the internal organs, especially the digestive system – nausea, indigestion, heartburn. In addition, the appetite grows, while the body requires something fatty or salty.

Immunity decreases, therefore it is very easy to get infected, not having slept for two days and two nights.

And then a paradoxical situation occurs – a person who has not slept for two days cannot fall asleep. The fact is that the body responds to this sleep deprivation by producing waking hormones, hence insomnia.

Three days without sleep
The condition will be basically the same as after two days of waking. Only all the sensations will worsen: the lack of coordination will increase, the speech will be simplified even more, there will be difficulties with concentration of vision. Depleted nervous system will lead to a nervous tic.

Digestive problems remain, but the appetite is gone. A man will freeze, a chill will beat him, he will constantly wrap up.

Four or five sleepless nights
The brain starts to turn off. There are lapses in consciousness. So, a person does not remember where he was going, did not notice that he had already passed several stops, did not understand how he got to this place.

Visual hallucinations
Consciousness begins to be confused, hallucinations can occur – visual and auditory, so-called panic attacks develop – bouts of fear with a strong heartbeat and cold sweat. Begin to shake hands.

After five sleepless days, the neural connections in the brain are broken. There are pains in the heart, immunity falls, the functions of the internal organs are disturbed.

Naturally, the appearance suffers – the person seems to be aging for a dozen or two years.

Six to seven sleepless nights
After such a marathon, a man looks completely insane. He has strong and vivid hallucinations, delirium, symptoms of paranoia, his speech finally loses connectivity and becomes slurred, his hands tremble violently. Some develop signs of Alzheimer’s disease.

More than seven days without sleep can be fatal. But it all depends on the individual characteristics of the person. There are people who managed to step over this line.

Records of wakefulness
The record – 11 days without sleep – was documented in the Guinness Book of Records in 1964. Its owner is 18-year-old Randy Gardner from America. It was not easy for him: his hands were trembling badly, hallucinations appeared, symptoms of paranoia were observed.

Do not sleep more than 11 days is life threatening
Most recently, this record was repeated by the 42-year-old Englishman Tony Wright – he also spent 11 full days without sleep. True, the Guinness Book did not get – its representatives refused to register such achievements because of the danger to human health and life.

How to recover after several sleepless days
Actually, it’s very easy to sleep. Moreover, even having slept only 8 hours, the person will fully recover and all unpleasant symptoms will disappear. Both Randy Gardner and Tony Wright, having rested and slept after the experiment, felt good, and the next day Gardner spoke to reporters and spoke without hesitation, and he looked beautiful.

But this does not mean that one can conduct such experiments on oneself all the time – the consequences will be very serious. This hormonal imbalance, and heart disease, and. of course, mental disorders.
