The basic cause of lumbar herniated disc is lumbar disc degeneration, lumbar trauma and accumulated strain. Therefore, through exercise, the bones and lumbar back muscles will be strong, the nervous system response will be agile, so in engaging in various activities, the movement will be accurate and coordinated, the lumbar spine is not easy to occur injury; at the same time, exercise is conducive to reducing the load on the lumbar spine, delaying the degenerative changes of the lumbar intervertebral discs, thus preventing the occurrence of lumbar herniation. The way of exercise can vary from person to person, according to local conditions, such as doing radio exercises, aerobics, playing Taijiquan and other kinds of sports activities can be. Second, maintain the correct labor posture correct posture can not only improve labor efficiency, but also prevent lumbar muscle strain, 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 contraction, bilateral hip muscles contracted inward, so that the pelvis tilted forward, the 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. The nature of the work requires semi-bending workers (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. When bending over to carry heavy objects, you should first stretch your waist, then bend your hips and squat, then straighten your hips and knees with force, and lift the heavy objects with your waist; when lifting heavy objects collectively, you should straighten your chest and waist, first bend your hips and squat, then hold the heavy objects at the same time. Third, do a good job of labor protection, improve labor conditions often bending labor or picking heavy objects, a wide belt to strengthen the stability of the waist. But the wide belt can only be applied during labor, usually to unwind, otherwise it can lead to a weakening of the waist, and even lumbar muscle atrophy, instead of producing low back pain. No matter what labor, what occupation, in a fixed position, labor time is not too long. Especially the work of bending or repeatedly twisting the body, to regularly replace the posture, so that the fatigued muscles get rest. Car drivers in the seat for a long time to bear the bumps, vibration, over time, the lumbar intervertebral discs under increased pressure, prone to intervertebral disc degeneration, resulting in disc herniation. So the driver should have a reasonably designed seat, pay attention to the correct seating position, to avoid or reduce vibration. During the driving period should be appropriate to let the lumbar activities and rest. The intrusion of wind, cold and damp can reduce the immune function of the body, small blood vessel contraction and muscle spasm, causing low back pain. Persistent spasm of the muscles of the low back can lead to an increase in pressure within the intervertebral discs and induce lumbar synostosis. Therefore, both in productive labor and in daily life, it is necessary to avoid the intrusion of wind, cold and damp. Women during pregnancy and lactation, due to endocrine changes, the muscles, joint capsule and ligaments of the lower back and pelvis relax, the load on the lower lumbar spine increases, the pressure within the intervertebral discs rises, and lumbar synostosis easily occurs. Therefore, during pregnancy, lactation should avoid heavy physical labor. Fourth, quit smoking too much can also occur low back pain, this is because some chemicals in tobacco can make the vasoconstriction, vascular wall ischemia and hypoxia, the intervertebral disc nutritional status deterioration, thus accelerating the degeneration of the intervertebral disc. At the same time, smoking can cause coughing, and severe coughing can cause pressure in the intervertebral disc to rise, promoting disc degeneration and leading to lumbar disc herniation, so you should quit smoking. Prevention of lumbar disc herniation should start from school, family, work and pre-vocational training, so that every worker understands the normal spine physiology, correct labor posture, pay attention to labor protection, and avoid accelerating lumbar disc degeneration and injury based on lumbar disc degeneration. Preventive measures should be done from the following aspects 1, should be regular for the youth or staff health examination, at the same time should be widely carried out to prevent lumbar disc herniation knowledge publicity and education. 2, the labor department should specify the maximum amount of load engaged in labor to avoid overloading the spine prompted and accelerated degeneration. 3, the correct labor posture and the combination of work and rest. 4, strengthen muscle exercise strong back muscles, so that the balance of spinal strength can prevent soft tissue damage to the lumbar back and reduce the occurrence of lumbar disc herniation. Health education 1, maintain good living habits, prevent the waist and legs from getting cold, prevent overexertion. 2.Standing or sitting posture should be correct. The incorrect spine will make the lumbar intervertebral disc unevenly stressed, which is the biggest hidden danger of lumbar disc herniation. The correct posture should be “standing like pine and sitting like a bell”, chest up, waist straight. The same posture should not be maintained for too long, appropriate in situ activities or low back activities, can lift the low back muscle fatigue. 3, exercise leg bending amplitude is not too large, otherwise not only will not achieve the desired purpose, but also cause lumbar disc protrusion. 4, do not bend when lifting heavy objects, should first squat down to get heavy objects, and then slowly get up, try to do not bend. 5, sleeping bed should choose a hard bed or put a hard Simmons and other flexible sleeper on a wooden bed, sleeping position to double lower limbs slightly flexed, side lying position is good.
