Workers who have been engaged in accounting, writing, editing and proofreading, typing, secretarial and other occupations for a long time, because of their long-term work at their desks, have left the cervical spine in a flexion position or in certain specific positions for a long time, which not only increases the pressure in the cervical intervertebral disc, but also makes the cervical muscles in an uncoordinated stress state for a long time. Muscles and ligaments at the back of the neck are easy to be pulled and strained, and the front edges of vertebral bodies are mutually worn and proliferated, coupled with excessive torsion and lateral flexion, which further leads to injury and cervical spondylosis. 1. office workers should first try to maintain a natural sitting posture and lean forward slightly to maintain the normal physiological curve of the head, neck and chest; The height ratio between the desktop and the chair can be raised or lowered to avoid excessive backward or forward flexion of the head and neck; In addition, it is more beneficial to adjust the sitting posture by customizing an inclined working board at 10 ~ 30 degrees with the desktop. 2. For long-term desk workers, the head and neck should be purposefully rotated left and right several times, about 1 ~ 2 hours, and the rotation should be gentle and slow to achieve the maximum range of motion in this direction; Or do a shoulder pinching exercise, slowly tighten the shoulder for 3 ~ 5 seconds, then hold the shoulder upwards for 3 ~ 5 seconds, and repeat for 6 ~ 8 times; You can also use two tables, put your hands on the table, fly your feet back, hold on for 5 seconds, and repeat 3 ~ 5 times. 3. Looking at things at close range for a long time, especially those who are in a bowed state, will not only affect the cervical vertebrae, but also easily cause visual fatigue and even induce ametropia. Therefore, whenever the desk is too long, we should look up and look far away. If you have neck pain, you can use the cervical health suit for exercise and adjustment. The suit has traction adjustment for the cervical vertebra, so that the cervical vertebra can be fully relaxed. After a long period of persistent exercise, the cervical vertebra will gradually recover. There are also examples of energy-gathering, muscle and bone pain-relieving plaster and cervical self-heating to protect the neck, which will have a good effect on cervical pain.
