How lack of sleep affects the body

To understand what happens if you don’t sleep all night, you first need to understand why sleep is needed and what processes are happening at this time.

First, during sleep, the body is cleansed of toxins and products of daytime activity. This is done by the lymphatic system, which works most efficiently in deep sleep. The same applies to the glymphatic system of the brain, which frees it from toxins.

Secondly, another important process occurs during sleep – the restoration of the ability of body cells to produce energy. When we sleep, the work of the immune system is also getting better, including protection against viruses and the destruction of malignant cells.

Thirdly, hormones are formed at night, including cortisol, on which all vital functions depend, including energy generation, maintaining pressure, and a sufficient level of glucose in the blood. In addition, in a dream, we remember and assimilate information, transform it into experience. This is probably where the expression “the morning is wiser than the evening” came from.

If lack of sleep is not your conscious choice, and you simply cannot fall asleep at night, there are several exercises that can help. Share them in the article.

What happens if you don’t sleep all night

Returning to the question of what happens if you do not sleep all night, everything becomes clear. If you stay awake during the day, nothing fatal will happen. However, many bodily functions may be impaired.

Lack of strength

Obviously, we will not be cheerful. Due to the lack of energy and the fact that everything is difficult. The slightest new information or task will cost a lot of effort, so even small things can be annoying.

Difficulties in solving problems

This is natural: the body just wants to be left alone. For many, after lack of sleep, speech suffers, these can be reservations and vagueness of wording. So it’s definitely not worth experimenting with interrupting sleep, especially before an important event, such as a speech or an exam.


Health problems

Due to the fact that the immune system did not have time to recover from lack of sleep, it is very easy to catch a cold and catch an infection. Therefore, after limiting sleep, it is especially worth avoiding hypothermia and drafts. Due to low levels of cortisol, a stress hormone, blood pressure and blood glucose levels drop, so some people experience weakness and a tendency to faint.

As you can see, even a single episode of lack of sleep can be unsettling. It is quite possible to survive if you follow the sleep schedule. But with its systematic lack of violation of these processes leads to serious consequences. Among them is an increased risk of Alzheimer’s disease and cancer. Therefore, you need to remember that everything is good in moderation.

If you sleep the prescribed norm of sleep, but still do not get enough sleep and constantly feel tired, this may indicate problems with the body. The possible reasons are discussed in the article.
