Often occupations require long standing, sedentary people, at the beginning may just be general lower back pain, or low back pain, if the time is long and do not pay attention to or adjust the posture, to do effective relief of lumbar intervertebral disc pressure action, the long-term accumulation of the intervertebral disc herniation may evolve into. Clinical practice has proved that the lumbar intervertebral disc pressure in the sitting position is the highest, standing position is in the middle, lying position is the lowest. The pressure on the lumbar intervertebral discs can be removed in the prone position. Through the lumbar intervertebral disc pressure measurement, it was found that if the standing position spinal load was calculated as 100%, the spinal load increased to 150% in the sitting position, while the standing forward bending position was 210%, and the sitting forward bending reached 270%. When standing with weight, the lumbar spinal load increases significantly. This shows that sedentary and weight-bearing are bad postures that lead to degeneration and injury of the lumbar spine. Studies have shown that when sitting with forward bending, the pressure on the lumbar intervertebral discs is 2.7 times higher than when standing, and even higher than when standing with forward bending. Therefore, the correct sitting posture is very important. Long-term sitting work, first of all, pay attention to the height of the table, chair, to avoid forward bending sitting position, in addition, long-term sitting workers should often change posture, regularly get up and move. In short, lumbar disc herniation is due to the lack of attention to some details of work and life, a moment to save trouble, or think that “the body is strong not to lose” did not use the correct scientific posture, resulting in the accumulation of lumbar spinal injury. Therefore, in order to protect the waist to pay attention to their every move.
