In daily life, study and work, there are a variety of activity postures, which also prompt people to develop their own habits, the correctness of which has an important impact on the human body. Therefore, the prevention of lumbar disc herniation requires us to pay attention to the rationality of our usual standing, sitting, and labor postures, as well as sleep postures. Correct bad posture and habits, strengthen exercise, enhance physical fitness, and especially strengthen the functional exercise of the lumbar back muscles. We need to understand that if proper exercise can improve muscle blood circulation, stimulate metabolism, increase muscle reflectivity and strength, correct the imbalance between the intrinsic and extrinsic balance of the spine, improve the stability, flexibility and durability of the lumbar spine, and thus play a role in preventing lumbar disc herniation. In many cases, a person’s sitting posture does not depend entirely on the person himself, sitting aids also play a role in the correctness of sitting or not. Sitting equipment is not suitable, but also can cause back pain. When sitting on a stool, because there is no backrest, people or naturally bend over, or straight waist sitting, can keep the lumbar spine in a natural flexion state, lumbar muscle is relatively in a relaxed state, when the stability of the lumbar spine by the ligaments around the lumbar spine to maintain the ligaments around the lumbar spine after sitting for a long time is prone to strain injury. Note on lumbar disc herniation: when sitting straight back, the lumbar muscle is in a contracted state, the lumbar back muscle continues to contract after sitting for a long time, prone to strain, both of which can produce back pain. The elderly and patients with a history of lumbar disc herniation lumbar back muscles, ligament elasticity and endurance is poor, there are varying degrees of degeneration or injury, not suitable for sitting on the stool, especially not suitable for sitting too low stool. Young adults are more suitable for sitting on a stool because of the elasticity and endurance of muscles and ligaments. Chair because of the backrest, can bear part of the body’s gravity, so that the lumbar muscles in a relatively relaxed state, but also does not increase the burden of ligaments around the lumbar spine, can reduce the chance of strain injury. When sitting in a chair, you should pay attention to the back of the back as close as possible to the back of the chair, when working, the chair should be pulled as far as possible to the table, shorten the distance between the table and chair. Lumbar disc herniation is a common clinical disease, currently 15%-20% of manual workers in China suffer from this disease. Lumbar disc herniation is the most common cause of lumbar leg pain in the clinic. It should be given enough attention. The human spine is composed of several vertebrae, and there is a disc-shaped elastic cushion between the two vertebrae, which is fixed by the fibrous ring and ligaments around it, and this disc-shaped cushion is what we call the intervertebral disc. It can play the role of cushioning pressure. Humans are upright animals, the greater the pressure on the intervertebral disc when standing, especially the lumbar intervertebral disc is more obvious, so the chance of injury is more.
