Cervical spondylosis is a common and prevalent disease among middle-aged and elderly people. In recent years, the incidence of cervical spondylosis has been increasing, and the age of the disease has a tendency to be younger. Cervical spondylosis can lead to neck and shoulder pain, dizziness, headache, limb weakness, etc. In serious cases, muscle atrophy, lower limb spasm, incontinence and paralysis may even occur. Therefore, the treatment and prevention of cervical spondylosis should not be underestimated. The occurrence and development of cervical spondylosis is a chronic, progressive, deferred process, and the causes are multiple. For example, long-term neck flexion, prolonged ambulation, unreasonable use of pillows, etc., can cause or aggravate cervical spondylosis. Cervical spondylosis belongs to the category of “paralysis” in Chinese medicine. The liver is the main tendon, the kidney is the main bone. When people reach middle age, their physique declines, the liver and kidney gradually lose, the qi and blood is insufficient, the tendons and bones lose nourishment, coupled with careless living, wind, cold and dampness invade and combine to become paralysis, the qi and blood does not pass, and if it does not pass, the pain appears in the neck or neck and shoulder stiffness and pain, headache, etc.; qi and blood deficiency, tendons and veins lose nourishment, and if it does not glory, the pain is seen in numbness, dizziness and other symptoms. The treatment of cervical spondylosis is mainly conservative treatment. Traditional acupuncture, tui-na and modern rehabilitation traction and intermediate frequency are the common means. The health care in daily life is the key to the treatment of cervical spondylosis, which is related to the success or failure of the treatment and the stability of the curative effect. The choice of pillow in cervical spondylosis health care is of paramount importance. The normal cervical vertebrae have a forward projecting arc, along this arc, the continuous, smooth arc curve formed at the trailing edge of each cervical vertebrae, which is often referred to as the cervical physiological curvature. It is the normal anatomical and physiological need of the cervical spinal cord, nerves, blood vessels and other important tissues. It can enhance the elasticity of the cervical spine, play a -determined role in cushioning oscillations and prevent brain damage. When degenerative changes in the cervical spine are caused by trauma and poor posture, the physiological curvature of the cervical spine will change accordingly, and consequently cause corresponding pathological changes, resulting in clinical symptoms. Sleep is the main physiological process to eliminate fatigue, in the sleep process, a reasonable padded pillow can make the stretched muscle group fatigue recovery, but also to maintain the physiological curvature of the cervical spine. Therefore, it is particularly important to choose a suitable pillow during sleep. The pillow should not only be able to well support the front convexity of the neck, but also be able to well accommodate the back convexity of the occipital part of the head (back of the head), because the occipital part of the head is protruding backwards, only then, the tissues and organs of the neck will be in a state of relaxation and rest. Inappropriate pillows, incorrect sleep posture, may cause excessive tension in the neck ligaments, muscles and accelerate intervertebral joint metamorphosis and lead to functional disorders. The pillow is too low, the head and neck will inevitably tilt back too much, the pre-convexity curvature increases, so that the muscles and ligaments in front of the vertebrae are overly tense, over time there will be fatigue, accelerating degenerative changes; sleep is easy to open mouth breathing, snoring, wake up will appear after the head, irritability, facial swelling. Pillow too high head and neck excessive forward flexion, the cervical spine rear muscles and ligaments are prone to strain, while the posterior wall of the dural sac of the spinal canal is stretched tight, the spinal cord forward, and compression of the spinal cord, hand and arm numbness; sleep, breathing will not be smooth, prone to dry mouth, sore throat, snoring, etc., will wake up feeling neck pain, headache, dizziness, tinnitus. So, how high the pillow is most appropriate? In general, the appropriate height of the pillow is generally 10-15 cm. People who are used to sleeping on their backs, the pillow height should be compressed with their fist height (fist tiger mouth upward height) the same as appropriate; and people who are used to sleeping on their sides, the pillow height should be compressed with their side of the shoulder width is appropriate.
