At present, there are as many as 50 million – 150 million patients with cervical spondylosis, and the incidence among adolescents has shown a significant upward trend. People spend 1/3 of the day in bed, improper sleep posture, will aggravate the pressure within the cervical disc, so that the surrounding ligament muscle fatigue, inducing cervical spondylosis, in order to make the cervical spine in sleep to maintain a normal physiological curve, should pay attention to the following points: a. The height of the pillow should be moderate The pillow is the main tool to maintain the normal position of the head and neck, this normal position is to maintain the normal curve of the head and neck segment itself. This weight curve according to ensure the external muscle balance of the cervical spine, but also to maintain the physiological anatomy of the vertebral canal, therefore, an ideal pillow should be in line with the requirements of the cervical physiological curvature, soft texture, breathable pro, to the middle of the low, both ends of the high yuan Bao shape is better, because this shape can use the middle of the depression to maintain the physiological curvature of the cervical spine, but also to the head, neck, play a relative brake and fixed Role, can reduce the abnormal activities of the head and neck in sleep, the pillow should not be too high or too low, do not “high pillow”, to the physiological position for the home, in general, the pillow high 8 to 15 cm is appropriate, in exchange for the formula, is (shoulder width – head width) / 2 height. Then there is the pillow core content selection is also very important, commonly used are: 1, buckwheat bark, inexpensive, breathable, can be adjusted at any time the height. 2, Pu velvet: soft texture, good breathability, can be adjusted at any time the height. 3, mung bean shell: not only good breathability, and cool relief, if coupled with appropriate tea and mint is better, but mainly for summer; others such as duck feathers are also good, but the price is higher. A reasonable pillow is very important for the treatment and prevention of cervical spondylosis, is not a substitute for drug therapy, should be long-term adherence. Second, the sleep position should keep the chest waist natural curvature, both hips and knees are flexed, is the whole body muscle relaxation, supine mainly, side lying as a supplement, to alternate left and right, side lying when the knee joint slightly flexed opposed, the head should be placed in the center of the pillow, so as not to fall into the pillow. Third, the choice of bed should be selected to maintain the crestal balance of the bed, to the bottom of the Simmons bed with a wooden board is better, spring bed on the crestal physiological balance is not beneficial.
