Hello friends! How often do you wake up in the morning feeling sleepy and in a bad mood? Or you try to fall asleep, tossing and turning all night, and as a result, weakness and low efficiency. I'm sure everyone has experienced this. First things first...

Dreams in the understanding of the past

Since ancient times, man has been trying to unravel such a phenomenon as a dream. And the question: how much sleep an adult needs per day, was also of interest to ancient scientists. In ancient Greece, it was believed that during dreams, blood fills the brain, and its outflow contributes to awakening. In Islam, this period is interpreted as something that steals the soul at night and resurrects in the morning.

Astrologers associated the period of night rest with something mystical, it is during this period that prophetic dreams are dreamed, which are more often seen by representatives of the air element. By the way, the scientist chemist Dmitry Mendeleev discovered the table of chemical elements in a dream and he is an Aquarius by sign.

Some physiologists have suggested that falling asleep occurs only at the moment when the brain activity is empty of various types of thoughts. I will say one thing, that there is truth in this, a person who all the time in experiences more difficultly flies into the world of dreams.

How much sleep does an adult need per day and what kind of Morpheus is he?

So what is sleep and why do we depend so much on its quality? Until the end, this physiological phenomenon has not been solved by scientists, however, a definition is given as a kind of gap between the mentally active state of a person and the outside world. Simply put, a kind of pause to restore the body's strength from all points of view. It is this state that occupies 1/3 of our life.

The period of dreams is usually divided into phases of sleep:

• fast phase or REM, characterized by a short period of 1-2 hours, at which point there is a rapid movement of the eyeballs under the closed eyelids, which distinguishes this view from the next, most interestingly, while the brain is in a state of wakefulness;
• The slow phase is divided into several stages:

1. Stage — superficial sleep , this period is very sensitive, so a person wakes up from the slightest noise;

1. Stage — physiological processes . At this moment, breathing stabilizes, body temperature, muscle tone, etc. decrease. At the slightest noise, awakening is possible.

1. Stage - transient, is a link between the previous and subsequent final stage. Brain activity at this point is reduced.

1. Stage - deep dream, during this period, the brain receives maximum rest from external stimuli, the body recuperates. It is very difficult to wake up a person, with a sudden awakening, as a rule, orientation in space and misunderstanding of reality are lost.

How much sleep does an adult need per day to be completely happy?

We are all different and our body's need for rest also depends on age, gender, the presence of chronic diseases, profession, etc. In the presented table, you can see what is the physiological need of a person for sleep per day, depending on various circumstances.

In many forums, there are disputes among users, what time should I go to bed? I will say one clear time that determines the moment when you need to urgently run to bed, no.

Many scientists, physiologists and doctors came to the same opinion that in order to get enough sleep and not feel overwhelmed in the morning, you need to go to bed no later than 23:00. This is due to physiological and biochemical processes that are regulated by a number of factors (mediators, etc.). If the recommendations are violated, as a result, a number of pathologies can be acquired, among which are neuroses, etc.

If your occupation involves shift work, after the night shift you should divide the total amount of time allotted for sleep into two sets. It is important to go to bed for 2-3 hours during the day, and take the rest of the time for the night period. Thus, there is a proper adaptation of the body to such a rhythm.

Why do we sleep

Some of us consider sleep to be a waste of time, however, this is an erroneous opinion, and I can argue:

• firstly, it is rest for the body, especially for the central nervous system, without rest for more than 5 days a person dies;
• secondly, it plays an important role in metabolism, at this moment certain substances are released that affect various biochemical processes, including metabolism;
• thirdly, it contributes to the assimilation of information, namely its sorting, obtained during wakefulness;
• fourthly, it helps to adapt to the temporary change day / night, thereby ensuring vigor and activity of the functions of organs and systems in the daytime. It also helps to recover during illness, which is priceless for health.

Why not sleep

I am sure that at least once, but you experienced such a state when you fall down, but putting your head on the pillow, you cannot fall asleep. Such incidents occur for a number of reasons, some are transient disorders, while others can signal serious illnesses. Our body is arranged very rationally, and as they say, it tolerates exactly as much as it can.

What can prevent a person from sleeping:

• malnutrition, especially overeating before bed;
• experiences and
• pregnancy;
• abrupt change in the hourly regime;
• taking certain medications that cause sleep disturbances;
• climatic factor (high temperature, humidity, etc.) and other reasons.

If these factors are eliminated, everything returns to normal and the usual rhythm is restored. What can not be said about other reasons that can affect the quality and duration of the period of dreams.

As a rule, they are a bell of severe diseases that require special therapy. In such cases, urgent consultation with a specialist is necessary.

Proper sleep reminder

For a good sleep, you need to pay attention to the following points:

• do not get carried away with food in the evening, overeating is not the best friend of weight and sleep. If suddenly there is a need, include vegetable food (light salads), fruits in the diet;
• take a walk before bed;
• the bedroom should be ventilated;
• a warm bath (you can add a decoction of herbs, valerian root, lavender, motherwort, etc.) or a shower relaxes and helps you fall asleep quickly;
• herbal teas (mint, lemon balm, linden and other herbs) and honey promote quality sleep;
• eliminate stress and anxiety factors, reading a book is suitable for this;
• at least an hour before a night's rest, forget about mobile phones, computers and other gadgets;
• if you are taking medications that disrupt sleep phases, the last dose should be no later than 16:00.
