Extended data:
The ancient view of "sit back and relax" is extremely harmful.
Only by maintaining the normal physiological state of the cervical spine during sleep can the skin, muscles, ligaments, intervertebral joints, trachea, esophagus and nerves passing through the neck relax and rest with the whole human body. Normal people sleeping on a high pillow, whether lying on their back or on their side, will change the physiological state of the cervical spine and make some local muscles of the neck excessively tense.
Over time, the neck muscles will strain and contract, leading to slight changes in the position of the cervical spine, which will stimulate or oppress the nerve roots and blood vessels of the neck, resulting in reflex spasm, and even insufficient blood supply to the brain, resulting in numbness of the neck, shoulders, back and arms, dizziness, headache, decreased vision, tinnitus, nausea, hearing loss and other symptoms. High pillow is one of the common causes of stiff neck and cervical spondylosis.
In addition, the high pillow will increase the included angle between the neck and the chest, hinder the ventilation of the trachea, and easily lead to dry throat, sore throat and nasal snoring. High pillows can also make the muscles of the chest and back tense for a long time, and the chest is compressed, which hinders normal breathing. If this goes on, it will definitely bring bad effects to the body.
Normal people to pillow, long-term low sleep, will also change the physiological state of cervical spine. Because there is no valve in the vein of the head, gravity can slow down the venous return of the brain and increase the blood supply of the artery, resulting in head swelling, irritability, insomnia and other discomfort. Low pillow is especially harmful to patients with hypertension and atherosclerosis.
