Healthy sleep: benefit and importance for the body

Almost a third of his life a person spends in a dream and without it simply can not do. In a person's sleep, the activity of metabolic processes and muscle tone decrease, the processes of anabolism go on more actively, nerve structures are inhibited.

All this contributes to the restoration of forces after the day's mental and physical labors. Sleep is not just a rest, but an active state of the organism, which is characterized by a special form of brain activity. In particular, during sleep, analysis and processing of information accumulated by a person for the previous time occurs.

If the process is successful, then the brain is freed from excessive information accumulated the day before, and is again ready to work. Thanks to this, the person normalizes the neuropsychic state, the working capacity is restored. Sleep provides programming processes in the brain and performs a number of other functions.

Sleep is a structurally complex phenomenon. It consists of at least two large stages, which regularly and cyclically replace each other:
    Healthy sleep: benefit and importance for the body
  • A slow sleep lasting 60 to 90 minutes; It, in turn, consists of several phases;
  • Sleep fast (paradoxical) - 10 20 minutes.
For a quick sleep, deeper structures of the brain respond, and in small children it dominates. With age, the proportion of slow sleep associated with younger evolutionary brain structures increases; It is more complicated.

For a long time it was believed that depriving a person of a fast sleep is harder for his health than for a slow one. But this is not the case - the normal structure of sleep is of primary importance; Certain ratios of the slow and fast phases. If this ratio is violated (what happens, for example, when taking hypnotic drugs), then a dream, even prolonged, does not bring the feeling of a desired rest.

If the dream is shortened, and the person does not manage to get enough sleep, then work capacity decreases and some neurotic disturbances occur; If the lack of sleep is regular, these changes gradually accumulate, and due to the deepening of the neurosis, severe functional diseases can occur.

A characteristic feature of fast sleep are dreams . Although it is now known that both fast and slow sleep can be accompanied by dreams, but bright, emotionally colored, sometimes with fantastic or detective storylines, dreams are most often made from fast sleep, when the brain works very hard, recalling its activity as a period of wakefulness.
Dreams are characteristic of everyone, but not all people and not each of them remember.
Freud considered dreams as a special and very important language of people's consciousness, as a breakthrough into the consciousness of the unconscious, often in a symbolic, veiled form. It is this feature that sometimes allows you to solve some difficult tasks in a dream, to make a breakthrough into a new area of ​​knowledge and even generate brilliant ideas.

Freud believed that in a dream, the struggle between the psycho-biological "I" of a person with various social limitations, which he is compelled to obey in a waking state, is because of which his psyche is in a state of constant tension. Thanks to dreams, when the barriers of restrictions are removed, the neuropsychic tension decreases (the Russian proverb also says: "Grief to sleep - I can not see grief").

Freud developed a special system of psychoanalysis, which is based on the interpretation of the dream symbols characteristic of this or that person, which allows us to find that chronic cause that causes a neuropsychological disorder. Symbols, the motivation of dreams depend on the psycho-physiological characteristics of a person, the level of his culture, environmental conditions that determine the needs, habits, interests. That is why numerous dream books that do not take into account all these features have no practical meaning.

The specific duration of sleep is strictly individual and depends on the nature of the previous activity, the general condition of the person, age, season, features of the person's GNI, and other factors. In particular, after intense mental or physical labor, a more prolonged sleep is required.

As practice shows, the main condition for the usefulness of sleep is its continuity - it creates the optimal conditions in the brain for processing information, for comparing the information accumulated over the previous day with the already established or genetically determined. It is thanks to this that the memory reserves are freed in the dream, the necessary information is erased and unnecessary reactions formed during wakefulness are eliminated.

Beneficial effect on the organization and structure of sleep is the habit of lying down and getting up at the same time. Due to this, a stereotype is formed, which automatically turns on at the set time, and the sleep occurs quickly and without difficulty.

This is of particular importance for mental workers, who, as is often the case, for various reasons, shift mental work to a later time, but such a regime can consolidate and gradually lead to sleep disorders, and then to pathology. It is necessary to take into account the biorhythmological features of a person. So, a typical "lark" goes to bed on average at 1.5, and rises for 2 hours before the "night owl".

For sleep disorders, it is advisable to make evening hours a time for rest and relaxation, as significant physical and mental stresses worsen the subsequent sleep. For the same purposes, in the evening, one should avoid highly emotional activities (disputes, viewing emotional TV shows, etc.), heavy and abundant food, beverages containing caffeine (coffee, tea, coca-cola), in general That, excitating the nervous system, disturbs sleep.

Sleep should be preceded by a calm atmosphere. Saturated interesting working day, reasonable combination of mental and physical activity, active and diverse rest, physical education are good preconditions for normal sleep. Evening walk is also useful.

If a person does not sleep well at night, one does not need to sleep during the day, but some people are helped by a short (up to half an hour) nap during interruptions between intense mental activity, which helps them to remove unnecessary tension and increase labor productivity.

Sleep better in a warm, dry, quiet, darkened room, on a not too soft, elastic mattress. Before going to bed, it's a good idea to do simple soothing procedures, for example, to take a warm shower, read a pleasing book. But the final choice of a mode of preparation for a sleep makes the person on the basis of own experience, conditions, the analysis of sensations and state of health.
