It is mainly to slow down the process of cervical intervertebral disc degeneration. Poor sleep position, improper work posture, and inappropriate physical exercise are common causes of cervical spine osteoarthritis degeneration. Developmental cervical spinal stenosis and congenital malformation of the cervical spine are potential factors in the development of cervical spondylosis. Prevention of cervical spondylosis can be started from the following aspects. Improving and correcting the sleep status People spend 1/3 of their day in bed, and improper sleep posture will intensify the pressure in the cervical disc, fatigue the ligaments and muscles around the cervical spine, and induce cervical spondylosis. In order to keep the normal physiological curve of the cervical spine in sleep, should pay attention to several points: 1, the height of the pillow should be moderate. The shape of the pillow to the middle of the low, high at both ends of the Yuan Bao shape is better, the advantage of this shape is that the neck can play a relative braking effect. 2, sleep position should make the chest, waist to maintain the natural curvature, both hips, both knees are flexed, so that the whole body muscle relaxation. 3, the bed should be chosen to keep the spinal balance of the bed, the Simmons bed with a wooden board as the bottom is better. Second, correct and change the bad position at work cervical degeneration and cervical spine for a long time in flexion or a specific position is closely related. Bad body position can lead to increased pressure within the intervertebral disc causing a series of symptoms. For a long time ambulatory workers recommended: 1, regularly change the head and neck position, reading and writing 30 minutes after the neck should be active, look up for half a minute, which helps to relieve neck muscle tension, but also to eliminate eye fatigue. 2, adjust the height and tilt of the desktop. Can make a sloping work board with the desktop is 10 ° ~ 30 °, when the work can reduce the cervical flexion and cervical interstitial pressure. Third, self-traction therapy When the neck feels sore or shoulder back, upper limbs have radiating pain, can self-traction neck to improve the symptoms, the method is: hands cross fingers together on the occipital neck, the head back, hands gradually force to the top of the head direction continuous traction for about 10 seconds, 3 to 5 times.
