Long-term engaged in accounting, writing, typing, office and other occupations, due to long-term sitting in front of the computer work, so that the cervical spine for a long time in a flexion position or some specific position, not only to make the pressure within the cervical intervertebral disc increased, but also to make the neck muscles in a long-term non-coordinated stress state, the back of the neck muscles and ligaments are susceptible to strain strain, the front edge of the vertebral body, mutual wear, hyperplasia, coupled with twisting, lateral flexion, excessive. This, coupled with excessive twisting and lateral flexion, further leads to injury and makes it easy for cervical spondylosis to occur. Prevention of cervical spondylosis should pay attention to the following points: 1, sitting correctly: to prevent the occurrence of cervical spondylosis, the most important thing is to sit correctly, so that the neck and shoulders relax and maintain the most comfortable and natural posture. Office workers, should also stand up and walk around from time to time, the activities of the neck and shoulders, so that the neck and shoulder muscles are relaxed to prevent chronic injury, but also to avoid prolonged sitting and lying on the sofa, prone position head turn and other actions. 2.Activate the neck: you should work for 1~2 hours, purposefully let the head and neck rotate several times to the front and back, and the rotation should be gentle and slow to achieve the maximum range of motion in each direction. The cervical joint fatigue can be relieved. 3, look up when a long time to see things up close: especially in a low state, both affect the cervical spine, but also easy to cause visual fatigue, and even induce refractive error. Therefore, whenever a long time after ambulation, should look up to the distance for about half a minute or so, which can eliminate fatigue, but also conducive to cervical spine health care. 4, the way to sleep: sleep not to sleep on top, the pillow can not be too high, too hard or too low. Pillow: the center should be slightly concave, the neck should be in full contact with the pillow and keep slightly back, do not hang. Those who are accustomed to side lying position, should make the pillow with shoulder height. When sleeping, do not lie down and read a book. Do not blow cold wind to the head and neck. 5, avoid injury: avoid and reduce acute cervical spine injury, such as avoid lifting heavy objects, emergency brakes, etc., because the cervical spine and its surrounding soft tissue injury can directly or indirectly cause cervical spondylosis, should be actively prevented. 6, prevent cold and humidity: prevent wind and cold, humidity, avoid wind and cold attack at midnight and in the early morning when bathing. Cervical spondylosis patients often have a close relationship with the wind and cold, humidity and other seasonal climate change. Wind chill causes local vasoconstriction and reduced blood flow rate, which hinders the metabolism and blood circulation of tissues. In winter, you should wear a scarf or a high-collared sweater to prevent the neck from being exposed to wind and cold. 7.Prevent infection: actively treat neck infection and other neck diseases. 8, adjust the height of the desktop and tilt: can make a desktop is 10 degrees ~ 30 degrees of the sloping work board, ambulation work can reduce the cervical flexion and pressure in the cervical space. When writing for a long time, the cervical spine is often in a forward-flexed, right-handed, left-leaning posture, too long, can cause the cervical spine arc changes, so should emphasize the “1 foot, 1 inch, 1 fist” of the correct writing posture.
