The belief is widespread that after tense business days you can sleep on the weekend or on vacation. We decided to check that from a scientific point of view, the lack of sleep in one day can be compensated by a long dream to others.

Many impatiently Waiting The next weekend, dreaming of getting enough sleep. After all, it is customary to compensate for the lack of sleep on weekdays with a longer dream on Saturday and Sunday, as well as on holidays. According to survey Superjob work search service, 11% of Russians want not to spend time with their family or go to nature on the weekend, but to sleep. Service Service "Work.ru" showed: 19% of respondents reported that they are not regularly sprinkled, another 61% are pouring out periodically, only 18% of respondents feel sleepy constantly. Plans sleep on weekend Dedicated Huge quantity memes and comic pictures. For example, one From the most Popular jokes beats homonymy the words "sprinkle".

Ned -sleeping is associated with a number of health problems. In a dream, the brain is successful Speaks from beta-amyloids, the accumulation of which is associated with the occurrence of Alzheimer's disease. Only one sleepless night (31 hours without sleep) increased the number of beta-amyloids in the brain of volunteers by 5%. Night without sleep equal By the destructive effect on the body, half a year with fast food: both reduces glucose tolerance and leads to a prediabetic state. Lack of sleep Curses And to mental changes: a regularly non -sleeping person loses the ability to distinguish a neutral or friendly expression on the face of the interlocutor and is inclined to interpret the facial expressions of other people as more dangerous. The risk of a heart attack of those who sleep less than six hours, increases 20%, and weight - by 12.5 pounds annually (about 5.5 kg). Therefore, scientists devote many studies to dream.

One of the largest tests Spended in Sweden. For 13 years, scientists have observed 43,880 volunteers, evaluating the most diverse parameters of their lives: the duration of sleep, the body mass index, smoking, the level of physical activity, work in night shifts, etc. It turned out that in a group of people up to 65 years old, sleeping five and less hours a day, the risk of death from all causes compared to this parameter for those who spalled those who spal seven hours. At the same time, those who fell asleep for everyday life on the weekend (slept eight or more hours), this risk did not increase, remaining an average level for the population.

However, a significant difference between the duration of sleep on weekdays and the weekend, as well as different times of going to bed, leads to such a state as Social Jetlag. Typically, the jetlag is called a sense of breakdown, accompanied by a variety of unpleasant symptoms, after a significant change in time zones due to a trip to the plane. Jetlag even specified In the international classification of diseases under the code 7A65 in the section of the Dream Cycle - wakefulness. Under the social jetlag, a person does not fly anywhere, but goes to bed on weekdays, for example, at 22 hours, then waking up at 6 in the morning, and the weekend arbitrarily changes this rhythm and goes to bed at 3 a.m. and sleeps until noon. Thus, he seems to cross five time zones, which is equal to a trip from Yakutsk or Chita to Moscow. Returning at the same time on Sunday in the evening to the weekday, he again “flew” - from Moscow to Yakutsk.

Social jetlag is extremely dangerous for the body: by calculations Scientists, every hour of the difference between the time of going to bed and awakening on weekdays and the weekend increases by 11% the probability of cardiovascular diseases. Social jetlag (understood as the difference between the average number of hours of sleep on weekdays and weekends) also Increases The risk of type II diabetes in the age group under 61 years is double. Brazilian researchers who studied social jetlag, discovered His connection with excess weight and obesity. Chicago scientists Studied The activity of American Twitter users, analyzing the time of publication of posts with geometers, and found out that the level of social jetting correlates with excess weight. Social Jetlag It turned out It is also associated with changes in blood indicators: a low level of high density lipoprotein (“poor” cholesterol), a higher level of triglycerides (leads to the development of atherosclerosis and heart disease and blood vessels), a higher insulin of plasma on an empty stomach and insulin resistance (signs of the possible development of diabetes).

Jetlag Calls Dot not only in humans, but also in bacteria that inhabit our gastrointestinal tract. Israeli scientists conducted a series of experiments on mice and a small group of volunteers, exploring the microflora of their intestines, after an arbitrary change in time zones. Although the bacteria of the intestines live their whole life in the dark, the change of time zones and the regime also influenced them. At the wrong time (before bedtime), those bacteria that are responsible for the breakdown of food were activated and demanded to go to eat, and on the contrary, “night” bacteria woke up during the day, which instead of digestion are normal for restoration work and purification of the body. American scientists notedthat the chronic jetlag in mice in three months led to the development of non -alcoholic fatty liver disease, which in some cases caused the development of hepatocellular carcinoma - one of the types of liver cancer.

And although the desire to sleep on the weekend, as Swedish scientists discovered, allows you to reduce the risk of premature death, there are many other health problems, from which a long sleep does not save us on weekends, and sometimes even creates them. Group of scientists from the University of Colorado Sicked 36 volunteers aged 18 to 39 years. The volunteers were divided into three groups: the first to be allowed to sleep every night for nine hours, the second was limited to five hours, the third group was given only five hours to rest, and they could sleep as much as they wanted to sleep. Members of both groups with a lack of sleep gained weight, an average of a kilogram in nine days of the experiment. Those who were sleeping a little straightened their health on weekends, but all the improvements came to naught, as soon as they again moved to five hours of sleep. For example, insulin sensitivity in a group with a five -hour sleep decreased by 13%, and in the group of those who could sleep for lack of sleep, the decline was from 9%to 27%. The professor of integrative physiology and the director of the laboratory of sleep and chronobiology Kenneth Wright, one of the authors of the study, summed up the results of the experiment: “Life in the yo-yo mode (toys working on the principle of the pendulum)-a change in the time when we eat and change our circadian hours on weekends, and then return to insufficient sleep, is extremely destructive.” Agree With him, Michael Tver, Director of the National Center for Research Studies of Sleep Disorders: “Frequent sleeping graphs is a form of stress associated with metabolic anomalies.” At the same time, scientists admit that an elongated dream on weekends can help those who do not sleep on weekdays not regularly, but only one day a week. However, this idea needs careful research.

Thus, the constant schedule with the same time for going to bed and awakening protects against a significant number of health problems. A long sleep on weekends certainly will not help to improve health, blown up by constant lack of sleep on weekdays. At the same time, if in general your sleep mode is balanced and only sometimes there is not enough sleep on everyday life, then it can be a good idea to sleep on the weekend longer. True, scientists have no experimental evidence of the benefit of such an approach.
