First, the role of the pillow It is generally believed that pillows are the fillers that people use for the comfort of sleep. From the perspective of modern medical research, the spine of the human body is a straight line from the front, and it has four physiologically curved curves from the side. Protecting the normal physiological curvature of the neck, maintaining people's sleep is a normal physiological activity, and people use pillows when they sleep. The pillow is generally composed of a pillow core and a pillowcase. The pillow core needs to be filled with materials to keep the pillow at a certain height during use. Currently, there are various filling materials on the pillow market. Traditional Chinese medicine and wild plants have been considered as the best pillow filling materials since ancient times. Traditional Chinese medicine believes that traditional Chinese medicine materials can be used as pillow filling materials to slowly exert their exertive power during long-term sleep and exert their different effects. It 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 consistent with the traditional Chinese medicine theory of "hot head and hot feet". Tea is a traditional filling material for the pillows of the past and the present, and the effect of mountain tea is better. According to the records, since the tea was discovered by humans, it was originally only medicinal. With the deepening of scientific research, the health care function of tea has been further explored. Modern scientific research shows that tea contains 500 kinds of ingredients beneficial to the human body. Therefore, they are also the most popular pillow material in the past. According to the health care of Chinese medicine, the use of pillows is most concerned about the height, low, soft, hard and air permeability of the pillow. [Guidelines for the use of pillows] First, the reasonable height of the pillow The view of “staying in peace of mind†is extremely harmful. According to science, it should be "high-lying and worryy". Professor Li Zhiguang, a professor at Beijing Medical University, said that maintaining the normal physiological state of the cervical spine during sleep can make the skin, muscles, ligaments, intervertebral joints of the neck and the trachea and esophagus through the neck. And the nerves and other tissues relax and rest with the whole person. If a normal person sleeps high, the physiological state of the cervical vertebra will change, and the local muscles in the neck will be over-stressed. Over time, there will be cervical muscle strain, airway, nerves, blood vessels under compression, stiff neck, cervical spondylosis, insufficient blood supply to the brain, etc. (a series of symptoms (neck, shoulder, arm numbness, hearing, vision loss, throat, nose)鼾, etc.). Sleeping low pillow is also not conducive to health. When sleeping under the influence of gravity, the blood in the brain is relatively increased and there is a rise in head, irritability, insomnia, etc., which has a particularly adverse effect on patients with hypertension and arteriosclerosis. In general, people with high blood pressure, heart disease, and asthma need to sleep a little higher; those with low blood pressure and anemia need to sleep low. Second, the reasonable hardness of the pillow Generally speaking, the harder pillow is good for human health, but the hard pillow makes the head and the pillow have too little contact surface, and the partial pressure is too large, which makes people feel uncomfortable. In the morning, the head, neck and back are produced. Symptoms such as numbness or pain in arms, hands, etc.; too soft pillows are difficult to maintain the height of the pillow, and because the skin is too soft, the compression area of ​​the scalp is large, which is not conducive to blood circulation, and also has the problem of breathability, and cannot guarantee sleep. The head skin is fully breathed, and it can cause a safety hazard of suffocation when lying on its back. Third, the pillow breathability and flexibility The breathability and elasticity of the pillow are mainly for the pillow of the soft pillow material, because other filling materials such as cassia seed, silkworm sand, bamboo charcoal, tea and the like can ensure that the pillow has good gas permeability and does not collapse without elasticity. According to medical investigations, the supine posture has a certain proportion in the sleep process of each person. Pillows with poor ventilation performance can make people in sleep have poor breathing, which seriously affects the health of the person and may even cause safety problems. Fourth, the reasonable position of the headrest It is very important to have a reasonable position of the head on the pillow when sleeping. Generally speaking, the head is preferably placed in the center of the pillow. This is to stabilize the sleeping position and avoid frequent shifting of sleeping position at night to cause stiff neck; The neck has a certain supporting force to maintain the normal physiological curve of the body. If you use a non-elastic pillow material, you can flatten the middle of the pillow and raise the pillow at the neck, so that the cervical vertebra can neither bend forward nor bend, and maintain proper rear extension. Will have cervical pain. [Pillow maintenance] The same as bedding, people usually pay attention to clean and dry the bedding, pillow towel, pillowcase, but rarely "please" the pillow to the outside of the air, dry. As everyone knows, when sleeping every night, the pillow is the "throat of the throat" that is passed by the dirty atmosphere of the cockroach. In addition, when the person sleeps, the impure gas exhaled in a large amount penetrates into the place of "dirty and dirty". It is only by cleaning the outer pillows and pillowcases that only the symptoms are not cured. The filth in the pillows cannot be removed, so the pillows have become a blind spot in modern families. In particular, it should be noted if it is a blind spot of the respiratory tract, digestive or head skin. Bacteria and viruses are also contaminated in the pillow and may cause cross-infection between couples or children. Therefore, pillows should be air-dried and disinfected frequently, and kept hygienic. In addition to drying the pillows, the pillows should be replaced frequently. According to medical experts, the pillows should be replaced at least once every two years and once a week.
Second, the structure of the pillow
Pillows that are too high or too low are not good for human health. The general understanding is that people who are used to lying on their backs have a high fist, and those who are used to sleeping on the side are more suitable for a boxing and a half. However, according to medical investigations, healthy people change their postures by about 20-45 times during 8 hours of sleep and half of them change in less than 5 minutes, 60% of which are supine, 35% are lying on the side, and 5% are prone. Therefore, the height of the pillow is discussed by people. It is related to fat and thin, shoulder width and length of the neck. There is no certain standard. However, the average person's sleep is more time due to the use of supine posture. It is recommended to use a little more punching height, which is not suitable for a boxing and a half height.
