Lack of sleep affects health. It's known to everyone. What is insomnia? This is a chronic lack of sleep, as a result of which a person does not have the opportunity to fully restore his strength in order to live a normal active life..

Prolonged insomnia, whether voluntary or involuntary, can lead to irreversible changes in the body.. Of course, they do not occur immediately, but as a result of systematic chronic lack of sleep..

Achievements and records For over forty years, there have been enough enthusiasts who, in practice, are trying to find out how long a person can live without sleep and what this is fraught with for physical and mental health. To date, the Guinness Book of Records has an official record - 19 days without sleep (set by American Robert McDonalds).

Also known is the schoolboy Randy Gardner, who managed to stay awake for eleven days.. Of particular interest is the fact that after that he slept for only fourteen hours, and not several days in a row, as it would be logical to assume.. But no, 12-14 hours is just enough for the human body to restore the normal wake-sleep cycle..

There is also an unconfirmed record - 28 days without sleep, but what does it mean in comparison with the ability of individuals not to sleep all their lives. Yes, it turns out that such people exist.. It is noteworthy that they have normal health and in all other respects they live the same life as we, “sleepers”. But this is rather a deviation from the general norms..

But ordinary people, workaholics, students, young parents and other people suffering from chronic sleep deprivation experience tremendous overload during their nightly vigils.. Here we will talk about them now.

The causes of insomnia can be very different, but the reaction to lack of sleep in most people is about the same..

What happens if you don't sleep? The first two days without sleep, the chemical processes in the body take precedence over the psyche, but the people around do not yet see this.. Of course, a person feels very tired and irritable.;

Consciousness begins to get confused due to changes in hormonal levels and disruption of communication between brain neurons;

On the third or fifth day, hallucinations and paranoia begin, and symptoms of Alzheimer's disease appear.;

After a week of lack of sleep, a person becomes a sick \;

Then comes the denouement - either a person falls asleep or dies (the exact timing is quite difficult to name, since each person is individual).

It should be noted that the human brain has one interesting feature - superficial sleep, with the help of which it copes with prolonged insomnia.. In essence, light sleep is a partial shutdown of the brain for a short period of time (from a few seconds to several minutes). Moreover, at this time a person can talk, walk and perform other actions.. Superficial sleep is useful and may delay death due to insomnia, but will not save you from it..

Interesting fact: according to NRMA statistics, one in six car accidents occurs as a result of extreme fatigue of drivers who fall asleep at the wheel.

What causes chronic sleep deprivation? Above we described what will happen if you do not sleep for a long time. Fortunately, this question is relevant for a small part of the population of our planet.. But almost every one of us experiences a constant lack of sleep, lacking sleep every day for several hours..

Ordinary lack of sleep calls out no less terrible symptoms, they just appear after a long period of time..

If you do not sleep for one day, then a person's ability to mental work is reduced by 30%, if you do not sleep for two days - by 60%. And if for one week you sleep less than six hours a day (recall that the need for sleep is eight hours a day), then the brain will suffer as if it had not slept for two nights in a row..

With chronic lack of sleep, oxidative processes begin to occur in the brain, which negatively affect mental abilities and memory.. The body ages faster, and the heart muscle wears out, as it does not have the opportunity to fully relax.

After 5-10 years of chronic lack of sleep, the human nervous system wears out, and every day it becomes more and more difficult for him to fall asleep.. In addition, the immune system begins to fail, because due to a short sleep, an insufficient number of T-lymphocytes that can resist bacteria and viruses are activated.. In addition to the poor physical condition, the psyche also joins, as the person becomes more grumpy and irritable..

From this, the following conclusions should be drawn: it is never worth raping your body, despite the lack of time, the requirements of the authorities and other factors. After all, nothing can restore human health.
