How does cervical vertebra curvature straighten cause

The curvature of the cervical spine straightens, mainly caused by two reasons: first, the cervical spine is in an incorrect posture for a long time: for example, long-term work or work at the desk, study, watch the computer, watch the mobile phone and other habitual movements, as well as sleep when using high pillows, can cause asymmetry in muscle strength on both sides of the neck, a long time in a state of tension and spasm, it will affect the physiological curvature of the cervical spine. Second, it is caused by the degeneration of the cervical spine: The degeneration of cervical vertebra includes degeneration of annulus fibrosus and degeneration of nucleus pulposus. The loss of water in annulus fibrosus, the decrease of height, the increase of activity, the brittle texture and the loss of water in nucleus pulposus can cause the narrowing of intervertebral space of cervical vertebra and the change of physiological curvature of cervical vertebra.
