What harm does the pillow have too high

The height of the pillow can make sleeping more comfortable, but it must not be blindly believed in "sitting back and relaxing", otherwise there will be worry. Here is a simple analysis of the harm that a pillow too high can cause to people:

Most of the nightmare phenomena that people say are caused by incorrect sleeping posture, especially the pillow is too high and the work pressure during the day is greater. This is a symptom of sleep paralysis.

If the cause of the disease is excluded, there is a brain neurasthenia such as neck pain, headache, dizziness, tinnitus and insomnia, or if you feel numb in your hands and feet halfway through sleep, it is likely that the pillow is too high. Many people in sleep, suddenly feel as if there are a thousand pounds of heavy objects pressed against the body, hazy breathless, as if awake not awake, as if sleeping rather than sleeping, want to shout can not be heard, want to move can not move, people feel puzzled and terrible, as if there is something pressed on the body, there are also people superstitious to call it "ghost pressing".

Usually dreaming occurs during the shallow sleep phase, and nightmares are when a person wakes up in a deep sleep. The central nervous system that controls human action is still dormant, but the part of the central nervous system that can convey consciousness is active, resulting in the situation that the person is conscious but cannot move. In addition to lying on high pillows, there are also those who like to sleep face down, or sleep with their heads covered, or cover the quilt thick or put their hands on the chest, excessive nervousness during the day, and excessive dinner.

Long-term high pillow will not only lead to carotid sinuses, but also affect the smooth flow of the respiratory tract, easy to snore, and easy to cause neck discomfort or hunchback. will keep the person's head in the highest position in the human body; It also artificially alters the natural physiological curvature of the cervical spine, making the tendons and meridians of the skin and neck tense. If the blood vessels in the head are in a state of insufficient blood supply and oxygen supply for a long time, it is disturbing, it is difficult to sleep at night, and once you fall asleep, it is easy to have nightmares.

The head is in the case of insufficient blood supply and oxygen supply for a long time, which will affect the metabolism of brain cells, resulting in memory loss in people, and the elderly have brain dementia and brain atrophy in advance. It is easy to cause hardening of the arteries, physiological garbage can not be removed in time and the formation of thrombosis, resulting in cerebral infarction, cerebral hemorrhage and so on.

Recommendations for the height of pillows

Regarding the appropriate height of the pillow, 10 to 15 cm is more appropriate, but the specific size depends on the physiological characteristics of each person, especially the physiological curvature of the neck. In the ancient Chinese medical books, it was pointed out that "the height and low size make the side lying just the shoulder level, that is, lying on the back and feeling comfortable." That is to say, the height of the pillow is appropriate to the degree of head and torso maintenance when lying on the back, that is, the pillow is one fist high when lying on the back, and one and a half punches high when lying on the side. Fat people with wide shoulders can have a slightly higher pillow, while thin people can be slightly lower.

Try to sleep on your right side and avoid the above triggers, and nightmares will not occur.
