In the 1960s and 1970s, the incidence of lumbar disc herniation was basically heavy manual laborers, such as: porters, miners, and farmers who work in the fields all year round; with the development of society, the incidence of disc lesions in the office workers is on the rise. Office workers work, the lumbar spine is subjected to a much smaller load than manual laborers, but the incidence of lumbar disc herniation is not lower than the incidence of manual laborers, in the end, what is the reason for it? The reason for this result is multi-faceted, sitting and desk height is not in harmony with with, sitting posture or bad posture for too long and lack of lumbar back muscle exercise, etc., can be induced by office workers lumbar disc herniation factors. So, how to prevent office workers suffer from lumbar disc herniation? We put forward the following suggestions: First, choose the appropriate sitting, as far as possible to reduce the strain of the lumbosacral region. So what is called the more appropriate sitting? The more reasonable seating requirements of moderate height, and have a certain angle of the backrest, such as armrests is better. In addition, should also pay attention to the distance between the sitting and desk and height coordination. The best not to sit on the sofa for a long time to make a report. Second, strengthen their own protection and exercise. For office workers to sit for a relatively long time and less movement, lower back muscles are weaker. Therefore, it is very important to strengthen their own protection and exercise to prevent lumbar disc herniation. Usually should take the correct office sitting posture, after working for a period of time, adjust their position, should not let the lumbar spine long-term in a forced position. Should also pay attention to strengthen the lumbar back muscle exercise, that is, from time to time to leave the desk, do back stretching, left and right rotation and other lumbar activities or daily regular lumbar back muscle exercise such as “five-point support”, “Yan Fei”, etc., you can also choose some suitable for their own health care exercises, You can also choose some suitable health exercises, tai chi and other exercise programs. Third, the rational use of air conditioning. Many modern offices have installed air conditioning, which undoubtedly in the hot summer for office workers to bring a cool working environment, but the room temperature is too low, too much cool air, so that the lumbar back muscles and intervertebral discs around the organization of the blood flow obstacles to increase the chances of lumbago. We believe that the room temperature at about 26 degrees is more appropriate, in addition, the air conditioning vent should not be on the waist and back.
