(from Latin somnus – a dream) is a functional state of the brain and the whole organism, which has specific qualitative features of the activity of the central nervous system that are different from wakefulness, with the disconnection of consciousness from the sensory influences of the external world. Sleep – a vital periodic occurrence, occupying about a third of life in a person. The absolute duration of sleep varies with age, has individual differences. Waking and sleeping form a single daily rhythm. Normal sleep is quite strong, giving after a feeling of vivacity and relaxation.


In sleep, the body rests.

Probably everyone on the question “Why do we need a dream?” firmly answer: “For the rest!”. However, this is not entirely true. According to the latest physiological and psychological studies, certain areas of the brain in the dream just work intensively. Processing and assimilation of the information accumulated during the day, systematization of the received experiences and sensations occurs. With the course of evolution we have developed an effective way to not miss the period of sleep. If you try to miss a dream at least once, you will feel depressed, distracted, tired. And then enough sleep a couple of hours – well-being will come back to normal. And the intellect, memory, feelings suffer in case of lack of sleep, much more physical health.

Sleeping helps to improve sleep.

Any sleeping pills give an “abnormal” sleep. Some drugs also completely disrupt the natural cycle of sleep, and are addictive – in the course of time larger doses are required to achieve the former effect. This applies less to homeopathic and herbal remedies. Sleeping pills are appropriate only in one case, if the state of sleep can not be achieved by any natural means. In other cases, you should avoid chemical help to your body.

Mandatory conditions for sound sleep are darkness and silence.

This is partly true. Silence and darkness, as a rule, help to fall asleep more quickly. Nevertheless, their absence is uncritical. If a person listens to the rhythm of his internal clock and goes to bed at the most favorable time, he can sleep soundly even in bright sunlight and slight noise (most often it’s the sound of TV, talking and traffic). This is due to the “blocking” of feelings during sleep. If you try to fall asleep in an unsuitable time for the body, such blockage does not occur – this was confirmed by studying the microcurrents of the brain. If you are trying to fall asleep ahead of time – rest assured that any noise will wake you up. Suffering insomnia should, first of all, determine the phases of its daily cycle, and only after that do it to ensure the silence and semi-darkness in the bedroom.

Daytime sleep hammers a normal night’s sleep.

Short sleep in the daytime on the contrary helps to reduce fatigue and keep the brain working at a high level. It will be nice if you can arrange for yourself 1-2 short breaks during the day. And this does not prevent you from sleeping soundly at night. Daytime sleep is desirable to arrange in the so-called “dead zone” of the daily cycle, then it will not bring down the time of a normal night’s sleep.

It is best to go to bed at the same time every day.

According to many methods of “right” sleep, you should go to bed at the same time all the time. This serves as a good prophylaxis, and maintains the biological clock of a human normally, and also allows you to gently “adjust” them to the desired regime of the day. However, it is very difficult for some people with certain mental characteristics (not just disorders) to follow this rule. In this case, attempts to force a person to sleep regularly at one time can cause sleep disorders, insomnia and other problems. The struggle with the natural daily cycle of a person never gives positive results.

Too long sleep reduces life expectancy.

According to the studies conducted, it turned out that people who sleep for 6-7 hours a day live longer than those who sleep more than 8 hours a day. But we must not forget – all are unique. If the rhythm of a person’s biological clock corresponds to a 6-hour sleep, it is best for him to sleep exactly 6 hours. If the diurnal cycle forms 9-hour periods for sleep, then sleep is ideal for the health for exactly 9 hours. The longest live people whose sleep mode is the most natural and coincides with the biological daily rhythms of their body. Attempts to roughly transfer your internal clock to another time lead only to stress, sleep disorders and ultimately it also shortens life expectancy.

If you want to sleep during the day, then you are very tired, or the body is weakened.

Daytime sleepiness is absolutely natural and is explained by the fact that a person’s daily cycle involves not one but two periods of sleep. One of them – a night’s sleep, and the second – respectively, daylight. But in most people the second period is impossible because of daily activities, cases, etc. So if you are sleepy for the 6th or 8th hour of wakefulness, especially after a hard work – everything is in order with your body, it’s best to just relax and take a nap for half an hour. This will significantly raise the efficiency in the future working hours.

Alarm clock is an indispensable assistant of every person in regulating the daily cycle of wakefulness and sleep.

Surely for every second the alarm clock has become an indispensable assistant when it is necessary to get up very early. Unfortunately, the alarm clock can “upset” the exact mechanism of a person’s biological clock. Perhaps in the morning, under the hateful ringing, the same idea comes to your mind. The best way to adjust and maintain the cycle of the internal clock is to follow your feelings. Go to bed when you want it, and wake up yourself, without the intervention of various mechanical and electrical assistants. And then you will feel asleep and rested.

I sleep 3 hours a day and feel great.

The main thing in order to feel cheerful and rested is to observe the correspondence of the daily routine to its biological cycle. If you want to have fun all night long – there will be no problems. But with such a sleep regime for a week, a month or even longer, most likely, the benefit from the time you won will be insignificant in comparison with fatigue, insomnia, decreased efficiency and worsening concentration. And these signs are the true companions of crude interference in the natural mechanisms of regulation of our sleep.

You must go to bed before midnight.

Many people think so, but in reality it is not. Each person has his own individual rhythm of sleep-wakefulness, and subconsciously he always knows at what time he needs to go to bed, and when to get up. Therefore, sleep until midnight and after midnight is equivalent. Just for each individual, the most optimal and important are the specific hours of the day. There is no ideal time for everyone to sleep.

Over the weekend you can sleep off during the whole subsequent week.

There is an opinion that a person, if given the opportunity to get up when he wants, will sleep very much, storing sleep for the future, like subcutaneous fat. In fact, this, of course, is not true. Our body consumes exactly as much sleep as necessary. Even after half a year of lack of sleep, a couple of days of good long sleep are enough to be cheerful again and toned. Sleep is not a vessel that can be replenished “in reserve”, like, nutrients in our body.

The ideal time for morning awakening is with the rising of the sun.

It is a common misconception that the optimal time for awakening is the sunrise. This opinion is fundamentally wrong, because the best time for recovery is individual.Remember, the “right” clock for morning awakening is when you feel that you have already slept. The body “says” that he has already done all the necessary work to reorganize the information held at night, and now it’s time to get up. If you no longer feel like sleeping, and at the same time the sun rises – you can consider yourself lucky. But if your internal clock is set up for another time – do not “translate” them, it will only harm the body, and even a wonderful sunrise will be for you not at all in joy.
