There is a folk saying that “working prominently causes a herniated disc”, meaning that working hard and busily can cause a person to suffer from a herniated lumbar disc. Many people blame the occurrence of lumbar disc herniation on exertion, because some people do feel lumbar pain after a busy day at work. But in fact, the occurrence of lumbar disc herniation is not necessarily related to busy work or not, on the contrary, some people who work all day leisurely or even do nothing can also suffer from lumbar disc herniation, and it is difficult to heal. In fact, the occurrence of a herniated disc is related to a variety of factors, improper sitting is one of them. Young people are more likely to suffer from herniated discs There is a certain pattern to the emergence of lumbar disc herniation. The lumbar intervertebral disc is a water-filled soft tissue in the body, 20 to 40 years old because of the high water content, so young people are more likely to have a herniated disc, while over 40 years old, especially the middle-aged and elderly in their 60s, because of the dehydration and atrophy of the intervertebral disc, it is not easy to protrude, and even if it protrudes, it will not compress the nerve roots next to it, producing symptoms of back pain and leg pain. In the clinic, doctors encounter many elderly people who say that they had a lumbar disc herniation when they were young and that it has recently recurred. This idea is not necessarily correct, many cases are due to lumbar spine degeneration and lumbar muscle strain. The onset of lumbar disc herniation must have a traumatic process of significant sprain and contusion. The intervertebral disc consists of the nucleus pulposus, the cartilage plate and the surrounding fibrous ring, which is a firm, dense, relatively fixed cystic tissue capable of bearing body weight while tolerating lumbar flexion, extension and rotation activities, and the accumulated wear and tear reduces the firmness of the fibrous ring. Under normal circumstances, it is normal for the lumbar intervertebral disc to bulge around (bulge) under pressure, but when it develops into a disc herniation, there must be an instantaneous effect of significant external force to rupture the annulus fibrosus before it becomes a disc herniation. The incorrect sitting posture overloads the discs The occurrence of lumbar disc herniation is usually related to the usual improper use of the waist. The fibrous ring has a high degree of solidity, but excessive and repeated wear and tear, pulling and squeezing are the reasons why the quality of the fibrous ring decreases (degeneration). Repeated bending, turning, collapsing, sitting on a low stool in daily life will degenerate the annulus fibrosus and promote intervertebral disc degeneration. Long-term continuous and repeated lumbar force posture in daily life can damage the solidity of the intervertebral disc, on the basis of which a slight external force can cause the disc to protrude. Some information shows that many patients with lumbar disc herniation are clerical workers such as company employees, because of the usual sitting posture is not good, resulting in lumbar muscle tension, disc overload, over time, disc degeneration accelerated, easy to develop into disc herniation. Tips: do this to protect the waist 1, sitting position when the waist to straighten, not collapsed sitting, stretched legs. 2, do not sit for a long time on a low stool, sofa. 3, the waist has a warning signal such as soreness, do not sit on the sofa and other soft seats. 4, lift the object on the ground, to squat not bend over. 5, leg press, do not bend instead of hip flexion. 6.When sitting for a long time, use the pillow behind the waist to protect the waist, while standing up regularly to move the waist. 7, do not exercise the lumbar muscles when the back is sore. 8.Take heavy things with a cart, not by hand. 9.Sleep on a hard bed, not on a sofa or soft bed. 10.Don’t let the lower back get cold. 11, to do more swimming, backward walking and other exercises to exercise the lumbar muscles.
