We spend one third of life sleeping, provided that we get enough sleep. However, at the present pace of life, few of us spend an adequate time for sleep. Many people mistakenly think that lengthy wakefulness gives many opportunities: there is more time for work, entertainment, leisure. And some just for fun want to know how you can live without sleep. But systematically replacing bedtime with other personal affairs we, eventually, can face with very unpleasant consequences. What happens if you do not sleep for a long period of time? This will be discussed in this article.
Why do people sleep?
The exact answer to this question has yet been found. However, scientists presented evidences proving that sleep is very important for humans. At this time, slows down the work of all organs and body systems, even the heart rate, which gives the heart muscle an opportunity to relax. During sleep takes place the most active regeneration of cells. It has been found out that in this period happens regulation of emotions and memories acquired during wakefulness.
The brain does not sleep
In the human brain there is a center that controls the biological clock. When bedtime comes, this center gets triggered and consciousness is gradually switching off. First are slowing down the neurons responsible for associative links. Here comes a phase of deep sleep. Together with the blackout transmission of signals from sensory organs is also stopped (sight, hearing, smell). All mental processes are governed by a special regime of interaction and operation of specific groups of neurons. Thus, when it is time for us to sleep, the brain begins to work in a different mode. Moreover, the intensity of these processes is different at different stages of sleep. So sleeping is a very active, complicated and important process.
Why a person cannot fall asleep?
It sometimes happens that we don’t sleep not due to our free will. Sometimes for hours we’re trying to force ourselves to fall asleep or there are repetitive awakening during the night and wakefulness lasts until dawn. This is insomnia — the most common sleep disorder. What triggers this phenomenon? A person cannot fall asleep for various reasons, the main ones are:
- Emotional stress
- Information overload
- Physiological problems
All these causes are interrelated, one can be the result of another and sometimes people can suffer from several of the above phenomena. Such states, lasting a long time, can trigger the complete lack of sleep. And it is fraught with irreversible consequences. Even up to death.
Lack of sleep: consequences
On average for the overall well-being and high performance a person must sleep at least 7-8 hours a day. Of course, there are people for whom who 3 hours are enough, but this is an exception. So what happens if a person does not sleep?
- After a sleepless night the person has fatigue, concentration and memory are decreased
- 2-3 sleepless nights may violate the coordination of movements, deterioration of concentration and speech, may develop nausea and nervous tic
- After 4-5 nights without sleep appears increased irritability and hallucinations
- If the person is awake for 6-8 nights, appear gaps in the memory, trembling in the limbs, speech is significantly slowed down
- What happens if you do not sleep 11 nights in a row? In this case the person is in stupor and is indifferent to everything develops fragmented thinking. Ultimately, death can occur
Chronic sleep deprivation is no less dangerous
Systematic lack of sleep is detrimental to human memory. Occurs an accelerated aging, heart rests less and quickly wears out. Are observed disorders of the nervous system and already in 5-10 years of chronic sleep deprivation a person notices that has difficulties with falling asleep. In addition, immunity weakens. Due to the low duration of sleep T-lymphocytes are not produced in sufficient quantity, they help our organism combating viruses and bacteria. Also was proved that people, who feel a constant shortage of sleep, become more irritable.
How long can you survive without sleep?
In order to receive the answer to this question were conducted many experiments as by scientists and by enthusiasts. The unequivocal answer has not been found. Today the officially recognized record is wakefulness for 19 days. This amount of time spent awake an American Robert McDonald. There are people who never sleep. Usually it is a consequence of illness. After a severe fever Thai Ngoc from Vietnam hasn’t slept for 38 years. Someone can stay awake for 5 days, someone for 19 and such wakefulness wouldn’t have irreversible health effects. However we do not recommend you trying to achieve a new record. It is individual and depends on gender, age, physical condition of the body, and on numerous factors. Without sleep an average person can live 7 to 14 days, provided that this person will lead inactive lifestyle.
The benefits of daytime sleep
Daytime sleep has the most positive impact on human health. If for some reason the night's sleep was short, the afternoon nap will help to restore strength. The researchers found that only 26 minutes of daytime sleep significantly increase efficiency and attentiveness. This effect may persist for 10 hours. Scientific studies have shown that naps 2 times a week reduce the chances of coronary heart disease by 12%. If you take naps 3 times a week, the risk of this disease is reduced by 37%.
Positive effects of short daytime sleep:
- By 11% raises spirits
- By 6% is improved physical condition
- By 11% raises productivity

- By 9% increases brain activity
- By 14% decreases insomnia
Interesting information for car enthusiasts
Prolonged lack of sleep is equivalent to the state of the driver's intoxication. If the driver has not slept for 17-19 hours, his condition is similar to a condition when blood alcohol level is 05 ppm. 21 hours of wakefulness is equivalent to 08 ppm of alcohol. This status entitles to convict the driver for being drunk.
