First, the role of pillows

People generally think that pillows are fillers used by people for the comfort of sleep. From modern medical research, the spine of the human body is a straight line from the front, and it has four physiologically curved curves when viewed from the side. Protecting the normal physiological curvature of the neck and maintaining people's sleep are normal physiological activities. People use pillows when they sleep.

Second, the structure of the pillow

The pillow is generally composed of two parts: pillow and pillowcase. The pillows need to be filled with materials to keep the pillows at a certain height during use. At present, there are various filling materials in the pillow market. Chinese herbal medicines and wild plants have been considered as the best pillow filling materials since ancient times. Traditional Chinese medicine believes that traditional Chinese medicine materials as pillow filling materials can slowly exert their potency during people's long sleep, exerting their different effects. Can play a role in health care and even treatment of diseases. In particular, negative Chinese herbal medicines such as cassia seed and silkworm sand are most suitable for Chinese traditional medicine theory of “cool head and hot feet”. Tea is a traditional filling material for pillows from ancient to modern times. According to records, since the discovery of tea by humans, it was originally medicinal. With the deepening of scientific research, the medical and health functions of tea have been further excavated. Modern scientific research shows that tea contains 500 kinds of ingredients that are beneficial to human body. So they are also the most popular pillow material from ancient times to the present. According to traditional Chinese medicine, the use of pillows is most concerned with the high, low, soft, hard, and air permeability of the pillows.

Third, the use of pillow guidance

1, a reasonable height of the pillow

The idea of ​​"relief" is extremely harmful. According to science, it should be “high and worrying.” Professor Li Zhiguang of Beijing Medical University introduced that maintaining the normal physiological state of the cervical spine at the time of sleeping can enable the skin, muscles, ligaments, intervertebral joints, and trachea and esophagus of the neck to pass through the neck. With nerves and other organizations to relax and rest together with the whole person. Normal people sleep high pillow, will change the physiological state of the cervical spine, so that excessive muscle tension in the neck. Over time, cervical muscle strain occurs, airways, nerves, blood vessels are compressed, stiff neck, cervical spondylosis, cerebral insufficiency cause a series of symptoms (neck, shoulder, arm numbness, hearing, vision loss, throat, nose鼾, etc.). Sleeping at night is also not conducive to health. Under the influence of gravity, when the pillow is lowered, the blood in the brain is relatively increased and head up, irritability, insomnia, etc. are caused. This has particularly adverse effects on patients with hypertension and arteriosclerosis. In general, people with high blood pressure, heart disease, and asthma need a pillow that sleeps a bit higher; people with low blood pressure and anemia need to sleep low.

Pillows are either too high or too low to be detrimental to human health. The general understanding is that people who are accustomed to lying on their backs have high fists, and those who are accustomed to sleeping on the side of a pillow are more suitable. However, according to the medical survey, healthy people change their posture about 20-45 times during an 8-hour sleep and half of their postures change in less than 5 minutes. 60% of them are lying on their backs, 35% are lying on their sides, and 5% are lying prone. Therefore, the height of the pillows is related to people's opinions. It is related to fatness, thinness, shoulder width, and the length of the neck. There is no certain standard. However, most people sleep more often because of the use of supine posture. It is advisable to use a little more punch and not reach the height of one-half punch.

2, the reasonable hardness of the pillow

In general, harder pillows are good for human health, but the stiff pillows cause the head and pillow to have too little contact surface and the local pressure is too large, causing people to feel uncomfortable and produce head, neck and back in the next morning. Symptoms such as numbness or pain in arms, arms, hands, etc.; pillows that are too soft can hardly keep the height of the pillows, and because it is too soft to compress the scalp in a large area, it is not conducive to blood circulation, and there is also the problem of breathability that cannot guarantee sleep. The head skin is fully breathable, and it can cause safety hazards when it is lying on your back.

3, pillow permeability and flexibility

The air permeability and elasticity of pillows are mainly for pillows made of soft pillow core material, because other filling materials such as cassia seed, silkworm sand, bamboo charcoal, and tea leaves can ensure good air permeability of pillows, and they do not collapse without elasticity. According to medical surveys, supine postures occupy a certain percentage of each person's sleep, and pillows with poor ventilation performance can cause people in sleep to breathe poorly, thereby seriously affecting people's health and may even cause safety problems.

4, the reasonable position of the headrest

The proper position of the head on the pillow during sleep is very important. Generally speaking, it is best to put the head on the center of the pillow so that it can stabilize the sleeping position and avoid the frequent changing of the sleeping position at night to cause stiff neck; the second is to allow The neck has a certain bearing capacity to maintain the normal physiological curve of the body. If you use a non-elastic pillow material, you can flatten the pillow in the middle, raise the pillow at the neck, so that the cervical spine can neither flexion nor lateral bending, and maintain a proper rearward position, so that it will not rise in the morning. Will be cervical pain.

Fourth, the maintenance of the pillow

The same as the bedding, people usually pay attention to cleaning bedding, pillows, pillowcases, but rarely "please" to the outside air permeability, drying. As everyone knows, every night when sleeping, the pillow is the “throat tract” through which the filthy atmosphere passes, and when the person sleeps, the impure gas that is exhaled infiltrates in a large amount and becomes a “dirty and filthy” filth. Cleaning pillows and pillowcases on the outside alone is only a "treat of the symptoms," but the filthy atmosphere inside the pillows cannot be removed. Therefore, the pillows have become a blind spot in modern families. In particular, it should be noted that if the respiratory, digestive or head skin hygiene blind spot. It also contaminates bacteria and viruses in pillows, which may lead to cross-infections between couples and children. Therefore, pillows should be regularly sun-disinfected, maintain health, and conditional families, in addition to more drying pillows, pillows should also be replaced frequently, according to medical experts suggest that pillows replaced at least once every two years, once a week drying.
