Many people may tell you that there are many causes of lumbar disc herniation, such as: structural factors of the spine, physiological factors and racial and genetic factors, etc. In fact, the main reason for the rising incidence and youthfulness of lumbar disc herniation is that at least 80% of people use their waist improperly in their daily habits. Two small actions in daily life: 1, bending down to carry heavy objects, first bend waist or bend legs first? 2, the elderly go to the supermarket every day, in order to exercise, is it directly carry things home, or a cart prepared in advance to push back? The answer to both questions you will probably choose the former, then, you are one of the 80% of the people. Once a group of 57,000 people occupational survey shows that the following occupations have a high rate of lumbar disc herniation: 1, long-term office desk workers, of course, including the work family; 2, drivers; 3, engaged in long-term bending labor; 4, long-term weight-bearing; 5, long-term standing; Meanwhile, some of us will ignore a cause: the smoking factor. The nutrition of the lumbar intervertebral disc depends on the blood vessels around the disc to provide, the intervertebral disc is a lack of blood supply tissue, the blood vessels leading to the intervertebral disc is very small, nicotine within the cigarette will make the blood vessels constrict, reducing the blood supply to the lumbar intervertebral disc, so that the intervertebral disc degeneration, work a family plus smoking is like adding insult to injury. So we have to start from the following points to do to really prevent lumbar disc herniation: the first point: to maintain a good posture in daily life. The correct posture can not only improve labor efficiency, but also prevent lumbar muscle strain and delay intervertebral disc degeneration, thus effectively preventing lumbar herniation. Here are a few common postures that help protect the lumbar spine. Standing workers: hip and knee joints slightly flexed to about 15 degrees is appropriate, natural abdominal, bilateral hip muscles contracted inward, so that the pelvis tilted forward, lumbar spine straight. Sitting workers: adjust the height of the chair just so that both knees can flex and extend freely, the upper lumbar spine and backrest chair close to keep the spine straight. Chair sitting board can not be too narrow, should be able to hold the bilateral thighs as appropriate. Semi-bending laborers (such as cooks, hairdressers, etc.): keep the lower back straight, the two feet apart and shoulder parallel, so that gravity falls on both hips and feet. Heavy manual laborers: when bending over to carry heavy objects should first stretch the waist, then bend the hips and squat, then forcefully straighten the hip and knee joints, straighten the waist to lift the heavy objects; when lifting heavy objects collectively, straighten the chest and waist, first bend the hips and squat, and then hold up the heavy objects at the same time. The second point: strengthen the exercise, enhance physical fitness. Strong lumbar back muscles on both sides can stabilize the spine, prevent soft tissue injury and strain on the lumbar back, reduce the load on the lumbar spine, increase local blood circulation, and slow down the process of lumbar intervertebral disc degeneration. The way of exercise can be different from person to person, according to local conditions, such as doing radio exercises, aerobics, playing tai chi and other kinds of sports activities can be. The third point: avoid the waist to feel wind, cold and dampness. Fourth point: manual laborers, should strengthen the protection and protection of the waist. Certain working people who need to bend over for a long time, the pressure on the lumbar intervertebral disc is doubled compared to the general standing. If you bend over to carry water from the well, the pressure increases even more. The incidence of low back pain is higher in workers who work in a sitting position, such as drivers. Therefore, how to pay attention to the posture of labor, labor process to adhere to the appropriate activities, for interval exercise, to help prevent lumbar disc protrusion. For athletes and other workers engaged in strenuous lumbar sports, they should strengthen the protection of the lumbar back and conduct frequent health checks to prevent repeated damage. The fifth point: sleep on a hard bed, pay attention to the protection of the lumbar back. Sixth point: quit smoking. Too much smoking can also occur low back pain, this is because certain chemicals in tobacco can cause vasoconstriction, ischemia and hypoxia of the blood vessel wall, deterioration of the nutritional status of the intervertebral disc, thus accelerating the degeneration of the disc. At the same time, smoking can cause coughing, severe coughing will cause the pressure in the intervertebral disc to rise, promote disc degeneration, resulting in lumbar disc herniation, so you should quit smoking.
