1) Bad sleeping posture such as high pillow;

2) Improper working posture: Sitting in a sitting position for a long time, especially bending over to work, strains the muscle ligament tissue behind the neck. In addition, in the state of cervical flexion, the internal pressure of intervertebral disc increases greatly, which makes the nucleus pulposus move backward and degenerate;

3) Inappropriate physical exercise: Exercise beyond the neck's endurance causes trauma, so pay attention to the practice of the head and neck, and exercise is not recommended, because the cervical vertebra has degenerated;

4) Other diseases of the body can cause cervical spondylosis, such as endocrine diseases such as diabetes and hypothyroidism, and can also promote cervical degeneration.
