If long-term in a poor sleep position, the cervical spine will always maintain a tight state, the formation of cervical spondylosis in the long run. Sleeping on the right pillow to sleep and cervical spine are helpful. Choose the right pillow, you can start from the height of the pillow, curvature, as well as soft and hard and so on several aspects. 1, the height: the pillow should not be too high, otherwise it will lead to excessive bending of the head cervical vertebrae, and too low and will make people feel sleep is not solid, can not enter the depth of sleep. General choice of pillow height can be in accordance with their fist length equal value reference; 2, curvature: pillow curvature curve is also very important, general cervical traction pillow, health pillow on the neck can play a good support, massage role. Normally you can choose the middle low, high around the pillow, is conducive to restoring the curvature of the cervical spine; 3, soft and hard: If the pillow is particularly soft, a little pressure that forms a depression; or particularly hard, can not be plastic. Both are not conducive to sleep, so choose a soft and hard pillow. Healthy people’s cervical spine backward bending, showing a natural physiological curvature, can well support the head. And people with cervical spine problems, cervical muscle tension decreased, the physiological curvature of the cervical vertebrae gradually become smaller, or even an anti-bow state. Each person’s own cervical spine conditions vary too much, the suitable pillow is also different.
