The ancients said "sit back and relax", but modern medicine believes that a pillow that is too high or too low is not good for the cervical spine. The wrong position of the pillow will cause problems. It may be sore and uncomfortable in the short term, but it is difficult to avoid major surgery in the long term.

After reading the following picture and explanation, you will understand why hotels usually put 4 pillows:

★How to properly cushion the pillow during sleep is very important. The pillow must be cushioned to the neck. You can test yourself. When you lie down, if the lowest part of your chin is facing the sky, it means that the pillow is too low. If the chin is pressed down, the pillow is too high. The chin should be kept level for a comfortable and correct pillow height.

Sleep occupies one-third of life, posture must not be careless. For example, some parents think that when their children sleep on a hard bed, the bones will grow upright. In fact, the flesh of the hips, waist, and shoulders of the human body is somewhat different. The rigid bed will prevent the curve of the body from sticking to the surface of the bed, so that it cannot relax and rest. It is uncomfortable and unhealthy.

There are still many people who are used to not using pillows, their heads will be tilted back when sleeping, and the pressure on the cervical spine will be twice as high as when they are tilted forward. Over time, problems will surely occur. As for the height of the pillow, it can be lower for young people, and higher for older people, because the softness of the cervical spine will change with age. The older you get, the more rigid you need more support.

★When sleeping flat (back position), the pillow should fit from the entire head all the way to the neck, not to the shoulders, and not only to the back of the head. It is best to place a small pillow under the knee; when sleeping on the side, the height should be increased. Double the height and put a small pillow between your knees. Sleeping on your stomach is best avoided because the cervical spine will be exposed to excessive pressure. When you get up, remember to posture on your side, hold it up with your hands, and then get out of bed. Don’t just lie on your back. Sit up straight up. No matter how correct the posture is, it is not appropriate to fix it for too long. You must change it after a long time. You must turn over when you sleep. You must stand up and move after sitting for a long time to maintain your spine.
