There is natural physiological buckling of human cervical spine, and the important function of this curvature is to buffer the stress of cervical spine to some extent. Proper pillows are very important for keeping a healthy cervical vertebra. Many patients with cervical spondylosis will not choose suitable pillows for themselves, and some people even sleep without pillows.
The most typical manifestation of such patients is fatigue or stiff neck. Therefore, to prevent cervical spondylosis, it is necessary to maintain the physiological curvature of the cervical spine. The scientific pillow height is determined according to the physiological curve of the arrangement of seven cervical vertebrae in the human neck. Only by maintaining the normal physiological curvature of this curve can the muscles, ligaments and joints of the shoulder and neck be relaxed.

The height of the pillow has great influence on the quality of sleep. Too high or too low a pillow is harmful. Traditional Chinese medicine believes that too high a pillow affects the release of liver pulse, and too low a pillow affects the release of lung qi. Modern research also shows that high pillows hinder the blood circulation in the head and are easy to form brain hypoxia, snoring and stiff neck.
If the pillow is too high, it can't maintain the physiological curvature, which will increase the load of the cervical spine, make the back muscles tense and the head and shoulders can't relax; Too low a pillow will make the head bloodshot, and it is easy to snore and open your mouth to breathe.
Patients with hypertension, cervical spondylosis and spinal deformity cannot use high pillows; The low pillow makes the head congested, which is easy to cause eyelid and facial edema. Patients with lung disease, heart disease and asthma cannot use it.
