Sleep is a strictly biological evolutionary process. Over night we overcome several cycles. Each of them lasts 1,5-2 hours and is divided into certain phases, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. Net The stage of superficial sleep is replaced by the deep, and its - fast, or the so-called paradoxical phase, when there is rapid movement of the eyes with closed eyelids, heart rate and breathing increase, metabolism in the facial tissues increases and muscle tone decreases simultaneously. Then the entire process is repeated anew. Overnight, the sequence of stages varies 4-5 times.

All this time our body works "in the sweat of the face": it produces the necessary hormones, biochemical and biologically active substances that will ensure normal life activity of the person during the next day. But the body is straying from a given rhythm, if for one reason or another there is no full good sleep. Bad sleep cuts deep nasolabial folds, draws dark circles under the eyes and swollen eyelids, gives the skin a painful pallor and lethargy.

Let's say a person goes on a train. Yes, he is sleeping. But how? Constantly awakens from the knocking of wheels, from conversations in the next compartment, from the endless passions of other passengers on the car. Plus an unusual bed, uncomfortable posture. As a result, he remains in the stage of superficial sleep, or very quickly overcomes all phases and his body does not have time to solve his "night tasks". Accordingly, the metabolism is disturbed, including in the tissues of the face. Poor fluid circulation leads to puffiness, to bags under the eyes. Inadequate outflow of venous blood from the cranial cavity provokes a headache, and again there are swelling on the face. Muscles do not relax, they are constrained and tense. And a person feels that he has not slept all night.

Like I did not sleep in the car, but unloaded it.

There is a dependence of sleep on the character of a person. Confident people, as a rule, sleep peacefully, deeply and completely restore the stock of nutrients consumed per day by the body, emotional energy. But those who suffer from an inferiority complex usually sleep badly, spin and often wince in a dream, awaken. Naturally, stand up broken, somewhat "crumpled" externally.
