The cervical spine has a forward physiological curvature, and prolonged low head reversal and physiological curvature can cause straightening of the physiological curvature of the cervical spine, or even reverse arch of the physiological curvature of the cervical spine, which is a basic pathological change of cervical spondylosis. In some people, because of the basic pathological changes, tension and spasm of the vertebral artery can be formed, resulting in insufficient blood supply to the brain and symptoms of dizziness and confusion, which is often referred to as vertebral artery-type cervical spondylosis, and such symptoms may be more obvious when the head is rotated. Therefore, you should avoid lowering your head as much as possible, do massage and acupuncture around the cervical spine to relax the surrounding muscles and reduce tension for cervical artery stimulation, and if necessary, do cervical traction to restore the physiological curvature of the cervical spine to help improve clinical symptoms. And when you sleep at night, the pillow should not be too high, pay attention to protect the cervical spine, do not suffer from wind and cold.
