Human sleep time accounts for nearly 1 / 3 of our whole life, and pillows also accompany nearly 1 / 3 of our life course. Therefore, choosing a good pillow during sleep has a great impact on our rest state. Inappropriate pillows are often the bane of many neck, shoulder and back diseases. It is necessary to use pillows First of all, we must affirm the function of pillows. The human cervical spine has an arc, which is called physiological lordosis. In any case, it is most comfortable for the human body to maintain this natural physiological radian, including during sleep. The function of the pillow is to maintain this normal physiological radian when people sleep and ensure that the muscles, ligaments, spine and various tissues of the neck can be in a relaxed state. Too high a pillow is not good There is an old saying that "rest assured". In fact, the pillow should not be too high, just one punch high. If the pillow is too high, it will cause the neck muscles to be stretched for a long time, causing discomfort. If you lie on your back, a part of the pillow sinks just enough to support the neck bend. For a few people who like to sleep on their stomach, they should pay more attention to choosing thin pillows. It is not necessarily used as a pillow, but can also be padded on the abdomen to cushion the pressure on the internal organs when lying down. In addition, the position of our pillow is also very important. Although it's called a pillow, it's actually placed near the neck. Different sleeping positions and exquisite pillow materials Many people may not realize that there will be any problems with pillows, and they will not make a lot of efforts in choosing pillows. Every day the pillow is either too hard, or too soft, or very high, or very short; Some people even fill pillows with cotton, clothes and sponges, and many pillows are filled with spring pillows. Think about how tense the muscles of the neck and shoulders should be when you put your head in a very uncomfortable position for so long! Generally speaking, the material of the pillow should not be too soft or too hard, just moderate. Too hard pillows can lead to poor breathing during sleep, while too soft pillows can cause excessive pressure on the head and neck, resulting in poor blood flow. For people who like to sleep on their back, the material in the pillow must be soft and elastic. Porous fiber pillow is a good choice because it is breathable and elastic. For people who like to sleep on their side, the pillow needs to be a little harder. Press it down to ensure that the neck and body are straight and relax the neck muscles. Buckwheat pillow is very suitable, and this material is warm in winter and cool in summer. It can also change the shape along the movement of the head. It is very comfortable to use. People who like to sleep on their stomach can choose light and thin down pillows, which are fluffy and breathable, effectively reducing the oppression of internal organs. For people with cervical problems, you can choose a memory pillow. The memory pillow can fix the position of the head, prevent the problem of falling into the pillow, and reduce the sense of compression. Pillow cleaning is more necessary Our hair and face secrete more oil, and are easy to adhere to more dust and bacteria. Some people may drool when sleeping. Therefore, pillows are very easy to get dirty. Be sure to wash the pillowcase regularly and put the pillow in the sun for sterilization regularly. (outlook new era)
