A large part of life is spent in bed, but many people overlook the importance of pillows. Long term use of inappropriate pillows not only affects sleep, but can also cause cervical spondylosis. Today, pain experts will help you choose a suitable pillow. A pillow should not be too high or too low. We sleep for about eight hours a day, which means that one-third of our lives are spent lying down. The function of a pillow is very important. Both high and low pillows are generally not good for the cervical spine, and many cervical spondylosis cases are mainly caused by unsuitable pillows. If you choose a high pillow while sleeping, not only will it be uncomfortable and affect the quality of sleep, but it may also cause the cervical spine to bend forward during sleep, increasing the burden on the cervical spine. It may also cause fatigue and damage to the muscles in the cervical spine, leading to cervical spondylosis. If you choose a low pillow during sleep, it may cause insufficient support for the cervical spine during sleep, making it unable to relax and protecting the cervical spine. This can have adverse effects on the physiological curvature and muscles of the cervical spine, leading to cervical spondylosis. Cervical spondylosis refers to a clinical condition caused by intervertebral disc protrusion, ligament hypertrophy, or bone hyperplasia that compresses surrounding nerves, blood vessels, or spinal cord due to cervical degeneration and hyperplasia. It may lead to headaches, dizziness, shoulder and back pain, upper limb soreness and numbness, and even palpitations, chest pain, walking weakness, and many other symptoms. Not only the cervical spine is affected by not sleeping on a pillow. "Sleeping too much on a pillow can make you hunchback!" Many people have heard a similar saying from their elderly family when they were young. In fact, not sleeping on a pillow can easily cause continuous tension in the cervical muscles and ligaments during sleep to maintain the posture of the cervical spine, gradually leading to strain. After waking up, there is no clear and refreshing feeling, but rather a feeling of neck and shoulder soreness, dizziness, and discomfort. Long term non pillow use can cause the normal physiological curvature of the cervical spine to deform, making the originally curved cervical spine straighten or produce lateral curvature, thereby causing damage to the cervical spine. In addition, when lying on one side without a pillow, the neck muscles on one side may also experience spasms and pain due to excessive stretching and fatigue, leading to a "falling pillow". Furthermore, when lying on the back, if the head is excessively tilted back, it is easy to open the mouth and breathe, resulting in dry mouth, dry tongue, sore throat, and snoring. At the same time, it can also cause congestion in the head, causing swelling of the eyelids and face, and causing significant damage to the eyes. "Three inch worry free, four inch longevity", right? The onset of cervical spondylosis is related to whether the posture in daily life, work, and sleep is correct. So, if you have cervical spondylosis, how should you choose this pillow? There is a saying in the folk that "three inches worry free, four inches longevity", which means that the height of the pillow should be between three and four inches to promote sleep and promote good health. Is this statement reasonable? According to the physiological curvature of the cervical spine, age, and sleeping posture, pillows should also vary from person to person, and the best pillow is one that suits oneself. The ideal pillow height is to maintain the normal physiological curvature of the cervical spine in both supine and lateral positions without causing scoliosis. In principle, sleeping on a pillow will not cause the neck to twist, and after compression, it is generally suitable to use 6 to 10 centimeters. For those who are accustomed to sleeping on their backs, the height of the pillow should be at the height of their fist after compression
