Patients with cervical spondylosis need a good sleep position, so the height of the pillow is very important. The current pillow height in 5-12cm is the normal range, and the location of the pillow in the cervical occipital department is good, avoid the top of the head and shoulders. Pillow too high or too low on the neck also has a great impact, because the head and neck has a normal physiological curvature, that is, the cervical spine mildly convex. This physiological curve not only ensures the balance of the external muscles of the cervical spine, but also plays an important role in maintaining the physiological anatomical state of the spinal canal. So a pillow that is too low and too high will have a negative impact on the cervical muscles, ligaments, joint capsule, spinal cord, nerve roots and vertebrae. No matter which sleeping position, the pillow height to be able to maintain the normal curvature of the cervical vertebrae ortholateral position is appropriate. Should make the sleeper feel comfortable, in order to achieve the purpose of relaxing the muscles of the whole body, easy to eliminate fatigue and adjust the physiological state of the joints. A suitable height of the pillow, as well as the best position of the placement although it seems insignificant, but the person’s 1/3 time are required to sleep on it. Patients with cervical spondylosis need good quality pillow cores and placement in the cervical pillow for the best position to improve or avoid further development of cervical spondylosis.
