  1. Experiments were conducted during which people deliberately did not sleep for 11 days or even more (up to 19 days). After that, they got enough sleep and most of them did not experience the long-term consequences of such a one-time sleep deprivation. No one has done research on the “let's not let a person sleep and see how long they last” type, so it is impossible to reliably determine how much a person can do without sleep. One thing is certain: if any mammal is not allowed to sleep, it will eventually die.

    By the way, a significant part of our society deliberately harms itself in terms of sleep deprivation. Everyday lack of sleep on weekdays is a very common phenomenon! And, if you do not get enough sleep for a long time, then you may well face not the most pleasant consequences. Studies have reliably shown that prolonged lack of sleep is associated with an increased risk of developing Alzheimer's disease, arterial hypertension, coronary heart disease, heart attacks, strokes, as well as premature aging and immune suppression.

  2. Depending on how much you don't sleep.

    One sleepless night

    After one sleepless night, a person begins to experience fatigue the next day, his attention decreases and memory problems appear.

    Two or three sleepless nights

    After spending two or three days without sleep, a person begins to lose coordination of movement. Visual acuity and concentration begin to suffer. There are problems with speech — a person begins to speak up and skip letters in words. In addition, there is a nervous tic, as well as nausea.

    Four or five sleepless nights

    After four to five days without sleep, a person becomes extremely irritable. Even the most seemingly ordinary and everyday situations, such as the doorbell, can make him lose his temper. Irritability is not limited, a person begins to experience hallucinations and delusions.

    Six to eight sleepless nights

    A person who has not slept for six to eight days begins to slow down speech, as if he was under the influence of a powerful anesthetic. There is a tremor in the limbs, weakness becomes very noticeable. Moments of short-term memory loss begin to appear. Unusual behavior is observed.

    Eleven nights without sleep

    The Guinness Book of World Records lists a record set in the winter of 1963 by 17-year-old schoolboy Randy Gardner, who with his classmates decided to find out what happens to a person who does not sleep for 11 consecutive days. Fortunately, this experiment ended without a fatal outcome (although previous experiments were less successful), but towards the end of it Gardner was not at all like himself. He could not focus his eyes on a particular thing for a long time, he forgot what he had said a moment ago, his speech often became slurred, he experienced disorientation, and as a result, he was simply tormented by hallucinations. Fearing for their son's future health, Randy's parents took him to the hospital. However, doctors did not find any brain damage or any other physical abnormalities in Gardner. After the check, the teenager fell fast asleep and slept for almost 15 hours.

    After this experiment, representatives of the Guinness Book of World Records said that they would no longer register attempts to break this record for finding a person without sleep, although such attempts were still made in the future. As a result, two weeks after the completion of the Gardner experiment, a new record was set by Jim Thomas, who lasted 266.5 hours without sleep. The last one was recorded in 2007. Briton Tony Wright was able to stay awake continuously for 275 hours.

  3. I will judge by myself, believe it or not, but I once spent 6 and a half days without sleep. In the first 3 days, I felt more or less normal and behaved, not counting the sharp changes from fatigue to energy and euphoria, but on the 4th-6th day it was quite funny, I saw various hallucinations like floating walls and distant voices, and even saw myself from the 3rd person. I remember thinking that I would fall asleep instantly when I was driving home, as a result, I fell asleep for about 3-4 hours and slept only 6 hours. Surprisingly, in addition to this, I also consumed alcoholic beverages, now I remember and wonder. We didn't manage to conduct more such experiments, but sometimes you want to break your record. Such cases. 🙂
