Healthy adult sleep: duration, what kind of sleep is considered healthy and how to provide it
What should be the sleep of a healthy person in order for all organs and systems to function properly? What rules of healthy sleep should any adult follow?
What should a healthy person sleep like?
The duration of a healthy person's sleep in order for the body to function “like a clock" should be at least 7-8 hours a day, and if you sleep this time, then increase the amount of sleep by 20-30 minutes. And do not eat at least 2 hours before going to bed, and preferably 3, because it is in a dream that the body is cleansed, because the liver works, and this is a given. If these words cause you distrust, then check for yourself: weigh yourself before going to bed and in the morning, and everything will become clear to you.
The importance of healthy sleep cannot be overestimated. Scientists have long established that during healthy sleep, a person gives the body the opportunity to feel relaxation and satisfaction, to which it responds with the production of leptin, a hormone that signals the absence of the need for food (leptin is produced when you are full). At the same time, regular lack of sleep leads to an increase in the amount of another hormone (ghrelin), which methodically makes us eat more, and overeating is one of the most common causes of body pollution. Everyone has had a chance to check the importance of healthy sleep for a person in practice – after a sleepless night, we almost unconsciously compensate for the hardships endured by the body and constantly chew something. Moreover, this something usually turns out to be either sweet or high-calorie, moreover, refined, since lighter food does not satisfy the appetite spurred by ghrelin, and food with a lot of fiber is simply not desirable, because the body, tired of lack of sleep, is too lazy to digest it. What kind of sleep is considered healthy from a medical point of view? One that satisfies the needs of the body, namely, a complete one. But at the same time, do not go to extremes and do not try to sleep for ten hours, hoping for the effects of leptin. It is enough to increase your sleep time by 20-30 minutes, if you, of course, sleep 7-8 hours a day.

What should be the sleep of a healthy person in order for all organs and systems to function properly? Proper sleep should be accompanied by diaphragmatic breathing. In most cases, such breathing occurs involuntarily in a dream. It is so useful in itself that it is the basis of a number of breathing techniques. Such breathing makes it possible to fill the blood with an increased portion of oxygen, which means faster delivery of all nutrients and vitamins to every cell of the body and, in addition, helps to improve metabolism.
How to ensure a healthy sleep
A person can negate all the benefits of the work of the diaphragm if he goes to bed with a full stomach. Numerous calls of experts to have dinner at least three hours before bedtime are not at all accidental – due to the close proximity of the stomach and diaphragm, they cannot work in parallel with one hundred percent efficiency, that is, a late (and even more dense) dinner guarantees you problems with digestion, and with full breathing, and with cleansing the body – instead of removing toxins accumulated during the day, the liver works on what you ate before bedtime. Remember how hard it is to breathe when the portion of what you eat is too large. Now imagine that in a dream the body is even harder, because you are trying to curl up or even lie down on your stomach. So, in order to ensure healthy sleep as required by the body, you do not need to fill up at night.
One of the basic rules of healthy sleep is the correct sleeping position. This is an extremely important detail – for the best work of all body systems, you need to sleep on your back, and if dinner was still not too light, then on your right side to give food the opportunity to proceed from the stomach to the intestines. Of course, sleeping on your back seems difficult at first, but in addition to a happy stomach, you will get a rested back and a healthy complexion. For beautiful ladies, another reason to learn to sleep on your back will be the ability to avoid morning puffiness of the face and early wrinkles on the neck (provided that the pillow is small). Therefore, lovers of chewing at night should gradually increase the time between the last meal and sleep. For those who categorically cannot sleep "on an empty stomach",
Sleep is a natural need of the body, and you should definitely not deprive yourself of this opportunity to restore your strength and strengthen your immune system. It is no secret that a person who is constantly sleep deprived gets tired quickly, easily irritated and looks at life without optimism, and these are clearly not the qualities that should be armed to cleanse the body.
In order for your body to be always healthy, it is necessary that the metabolism is normal, and this is not so difficult. You just need to eat right; move as much as it is necessary for you by nature; sleep well for a normal amount of time; To breathe fresh air. And at least sometimes be in the sun and every week – in the bath. Then everything will be fine with you, and you will not need unnatural hard cleansing.
How many phases of sleep does an adult have
Sleep is a cyclic phenomenon, usually 4-5 cycles replace each other in 7-8 hours of sleep. And how many phases of sleep does a person have in each of them? Each cycle includes 2 phases: non-REM sleep and REM sleep. When a person falls asleep, he begins a slow sleep, which includes 4 stages. The first stage is drowsiness; consciousness begins to “float”, uncontrollable images appear in the head. During the second stage, the person falls asleep completely. The third stage is deep sleep. The fourth stage is the time of the strongest and deepest sleep, it is quite difficult to wake a person during this period. During slow sleep, the temperature in the human body drops, breathing and heart rate slow down, muscles relax, metabolism decreases, the eyeballs under the eyelids make slow, smooth movements. During slow sleep, tissue regeneration occurs, and the production of growth hormone increases. It is thanks to him that tissue regeneration is carried out, for which energy is spent. If you do not sleep enough, then the growth hormone is not produced enough, which means that regeneration is not carried out enough, your body is not cleansed, and you age faster.
After about 1.5 hours, the phase of non-REM sleep of an adult is replaced by a phase of REM sleep. During this phase, the work of internal organs is activated in the body, while muscle tone drops sharply and the person becomes completely immobilized. The reverse processes of slow sleep begin to occur in the body: the temperature rises, breathing and heart rate increase, the eyeballs under the eyelids begin to move sharply, the metabolism accelerates, that is, your body, again, is cleansed, and you lose weight. It is during this period that a person sees most dreams. REM sleep lasts about 15 minutes. During the phase of non-REM sleep, the human brain processes the information received during the day. Closer to awakening, the duration of non-REM sleep decreases, while REM sleep, on the contrary, increases.
