Suitable pillow, easy cervical spine
For those who do not have good cervical spine and no movement, protecting the cervical spine can be performed during sleep, which saves time and effort. On the one hand you should choose the right pillow. First of all, the height of the pillow should be moderate, not too high, not too low, generally 10 to 15 cm is preferred. Second, the hardness of the pillow should be moderate. Finally, if you are accustomed to lying down, the middle of the pillow is best sunken, so that the head can remain stable in the depression of the pillow for a long time, not to stiffen the pillow. If you prefer to stay on your side, it is best to keep your pillow in the same position as your shoulders to reduce shoulder and neck weight. On the other hand, when sleeping, keep the spine in a normal physiological curvature. It is best to lie supine or sleep on the right side. If you feel comfortable when you get up early every morning, it's a good proof of your pillow and sleeping position.
