Chronic injury or degeneration of the cervical spine and soft tissues of the neck causes imbalance of the internal and external mechanical balance of the crest, which causes head, neck, shoulder, arm, upper limb, middle back, chest pain and other symptoms, and even combined with limb dysfunction and other clinical syndromes. In mild cases, headache, dizziness, nausea and vomiting, neck and shoulder pain, upper limb numbness, weakness, tinnitus, blurred vision, chest tightness and panic, etc. In severe cases, it may also lead to limb paralysis and urinary and fecal disorders. Cervical spondylosis does not include cervical spine fracture and dislocation caused by acute trauma, bone tumor, etc. There are many factors that trigger and aggravate cervical spondylosis, and the pillow used frequently during sleep is one of the important reasons. For the average person, at least 1/4 to 1/3 of the day is spent in sleep, so if the pillow is not used properly or do not use the pillow, it is easy to cause or aggravate cervical spondylosis. On the contrary, if you pay attention to and adjust the posture of the cervical spine in sleep, can also have a preventive and therapeutic effect. As the saying goes, “no worries about the pillow”, but it’s not true. Under normal circumstances the physiological curve of the cervical spine is convex, supine position, if the pillow is too low, the head and neck too much back, so that the convexity curvature increases, not only the muscles and ligaments in front of the vertebral body easily due to excessive tension and fatigue, and can cause chronic injury. At the same time, the posterior tissue of the spinal canal can protrude forward into the spinal canal, increasing the pressure in the spinal canal; excessive head and neck tilt also makes the spinal canal is elongated, the crestal medulla and nerve roots in the spinal canal become relatively short, in the role of other factors are prone to symptoms. If the pillow is too high, the head and neck too much forward flexion, so that the muscles and ligaments behind the vertebral body easily strained, triggering or aggravating cervical spondylosis. Thus, both healthy people, or people with cervical spondylosis, we must pay attention to maintain the physiological position of the cervical vertebrae convexity, to prevent or accelerate the degeneration of the cervical spine. The first shape of the ideal pillow in line with the overall normal physiological curve of the human body, so that when sleeping, regardless of supine, side lying, cervical spine parts, the whistling tract to restore the normal physiological curve. In order to effectively maintain the physiological flexion of the cervical spine, so that the neck muscles fully relaxed, the pillow should be adjusted to the middle low, high at both ends, neck and shoulder edge slightly higher, the edge of the low class saddle-like, which is often said to be B-shaped pillow. Reasonable pillow should be moderate in texture, non-elastic, rectangular. As each person’s size, shoulder width has individual differences, therefore, the height of the two ends of the pillow varies from person to person to ensure that the maintenance of cervical physiological flexion. For this reason, the pillow should be considered when making with adjustability, but also to facilitate the change of pillow height, to adapt to different sleeping positions (supine, side lying). 1, high and low curvature is very delicate. Pillow high low cervical spondylosis are not good. The height is appropriate. The appropriate height of the pillow to 6-10 cm more appropriate, the specific size also depends on the physiological characteristics of each person, especially the physiological curvature of the neck. These two different heights can ensure that the normal physiological curvature of the cervical spine in the supine and lateral position, that is, from the frontal observation of the cervical spine is a straight line, from the side observation of the cervical spine has a forward physiological curvature. In principle to sleep on the pillow will not make the neck distortion. People who are used to sleeping on their backs, the pillow height should be compressed and their fist height (fist up the height of the tiger’s mouth for the fist high standard) equal to; people who are used to sleeping on their sides, the pillow height should be compressed and their side of the shoulder height is the same as appropriate. Of course, regardless of supine sleep, side sleep can maintain the normal physiological curvature of the neck cervical spine pillow is the most ideal. 2, soft and hard moderate. Cervical spondylosis pillow should choose a slightly softer, but not lose a certain type of hardness, on the one hand, can reduce the pressure between the cervical spondylosis pillow and the scalp, on the other hand, and maintain the uneven pressure, so that the blood can pass from the pressure is less. Cervical spondylosis pillow as long as slightly elastic can be, elastic too big will cause neck muscle fatigue and injury. 3, pillow filler. Commonly used are: ① buckwheat hull: inexpensive, breathable, can always adjust the height of the pillow. ② Pu velvet: soft texture, good breathability, can be adjusted at any time the height. ③ mung bean shells: not only good breathability, and cool relief, if you add the right amount of tea or mint is better.
