General knowledge of pillows

  • Detail

1、 The function of pillows is generally believed that pillows are fillers used by people for the comfort of sleep. From the perspective of modern medical research, the human spine is a straight line from the front and has four physiological curves from the side. In order to protect the normal physiological curvature of the neck and maintain people's sleep is a normal physiological activity, people use pillows when they sleep. 2、 Structure of pillows pillows are generally composed of two parts: pillow core and pillowcase. Pillow core needs filling material

I. The role of pillows

generally, people think that pillows are fillers used by people for sleep comfort. From the perspective of modern medical research, the human spine is a straight line from the front, and has four physiological curves from the side. In order to protect the normal physiological curvature of the neck and maintain people's sleep is a normal physiological activity, people use pillows when they sleep

II. Structure of pillows

pillows are generally composed of two parts: pillow core and pillowcase. The pillow core needs filling materials to maintain a certain height when used. At present, there are a variety of filling materials in the pillow market. Traditional Chinese medicine and wild plants have been considered as the best pillow core filling materials since ancient times. Traditional Chinese medicine believes that traditional Chinese medicine materials, as pillow core filling materials, can slowly exert their medicinal power in people's long sleep, give play to their different effects, and can play a role in health care and even treatment of epidemics. In particular, cassia seed, silkworm excrement and other negative Chinese medicinal materials are most in line with the traditional Chinese medicine theory of "cooling the head and warming the feet". Tea is the traditional filling material for pillows from ancient times to modern times, and the effect of picking Alpine tea in that year is better. According to records, since tea was discovered by humans, it was only used for medicine at first. With the deepening of scientific research, the medical and health functions of tea have been further explored. Modern scientific research shows that tea contains 500 ingredients beneficial to human body. So they are also the most popular pillow material in ancient times. According to traditional Chinese medicine, pillows should be used in a high, low, soft, hard and breathable manner

III. guidance on the use of pillows

1. Reasonable height of pillows

"rest easy" view is extremely harmful. According to science, it should be "worried about high pillows". Director Lizhiguang, a professor at Beijing Medical University, said that only by maintaining the normal physiological state of the cervical spine during sleep can the skin, muscles, ligaments, intervertebral joints of the neck and the trachea, esophagus, nerves and other tissues passing through the neck relax and rest with the whole person. Normal people sleep on high pillows, which will change the physiological state of the cervical spine and make the local muscles of the neck excessively tense. Over time, a series of symptoms (numbness and pain of neck, shoulder and arm, hearing and vision decline, dry throat, snoring, etc.) will occur, such as neck muscle strain, airway, nerve and blood vessel compression, pillow, cervical spondylosis, and insufficient blood supply to the brain. Sleeping on a low pillow is also bad for health. When sleeping on a low pillow under the influence of gravity, the blood in the brain increases relatively, resulting in head swelling, irritability, insomnia, etc., which is particularly harmful to patients with hypertension and arteriosclerosis. Generally speaking, people with high blood pressure, heart disease and asthma need to sleep on a higher pillow; People with low blood pressure and anemia need to sleep on low pillows

too high or too low pillows are harmful to human health. The general understanding is that it is more appropriate for people who are used to lying on their backs to have a fist higher than those who are used to sleeping on their sides. However, according to medical surveys, healthy people change their posture about 20-45 times in 8 hours of sleep, and half of them change their posture in less than 5 minutes, of which 60% are supine, 35% are lateral, and 5% are prone. Therefore, the height of pillows depends on people, which is related to obesity, shoulder width and neck length, and there is no certain standard. However, because most people sleep in supine position for more time, it is recommended to use a little more than one punch height, rather than a punch and a half height

2. Reasonable hardness of pillows

generally, harder pillows are beneficial to human health, but strong pillows make the contact surface between the head and the pillow too small, local pressure is too high, and people feel uncomfortable, causing numbness or pain in the head, neck, back, arms, hands and other places in the next morning; Too soft pillows are difficult to maintain the height of pillows, and because they are too soft, they compress the scalp in a large area, which is not conducive to blood circulation. At the same time, they also have the problem of ventilation performance, which can not guarantee the full breathing of the head skin during sleep, and can cause suffocation when lying on your back

3. Permeability and elasticity of pillows

permeability and elasticity of pillows are mainly for pillows made of soft pillow core materials, because other filling materials such as cassia seed, silkworm sand, bamboo charcoal, tea, etc. can ensure good permeability of pillows, and they will not collapse without elasticity. According to medical investigation, supine posture accounts for a certain proportion of everyone's sleep process. Pillows with poor ventilation performance will make people breathe less during sleep, which will seriously affect people's health and even cause safety problems

4. Reasonable position of head pillow

the reasonable position of the head on the pillow when sleeping is very important. Generally speaking, it is best to put the head in the upper position in the center of the pillow, so as to stabilize the sleeping posture and avoid frequent switching of sleeping posture at night, resulting in falling asleep, etc; Second, it can make the neck have a certain supporting force and maintain the normal physiological curve of the body. If the pillow core material without elasticity is used, the middle of the pillow can be flattened, and the place where the neck rests on the pillow can be padded up, so that the cervical spine can neither bend forward nor bend sideways, and maintain a proper posterior extension position, so that the cervical spine will not be sore in the morning

IV. pillow maintenance

both are bedclothes. People usually pay attention to cleaning and drying bedding, pillow towels and pillowcases, but rarely "invite" pillows outside the house for ventilation and drying. As everyone knows, when sleeping every night, the pillow is the "throat" through which the dirty breath in the quilt passes. In addition, when people sleep, a large number of impure gases exhaled penetrate, making it a "dirty, messy and bad" place to hide and accept dirt. Only by cleaning the external pillow towels and pillowcases, it is only "a temporary solution, not a permanent solution". The filthy smell in the pillow core cannot be removed, so pillows have become a health blind spot in modern families. In particular, it should be noted that if it is a health blind area of respiratory tract, digestion or head skin. Bacteria and viruses will also be contaminated in the pillow core, which may lead to cross infection between husband and wife or children. Therefore, pillows should be often dried and disinfected to maintain hygiene. In addition to drying pillows, families with conditions should also often replace pillow cores. According to the recommendations of medical experts, pillow cores should be replaced at least every two years and dried once a week
