Lumbar disc herniation is a series of clinical symptoms caused by degenerative changes in the lumbar spine or by external forces that cause an imbalance in the internal and external pressure balance of the lumbar intervertebral disc, resulting in rupture of the lumbar annulus fibrosus and protrusion of the nucleus pulposus, thus compressing the nerve root or cauda equina. Some daily errors or improper activities can induce lumbar disc protrusion, and vice versa can prevent its occurrence. 1, what bed is good to sleep? Specifically, a thin mattress or cushion on a wooden bed, a hard brown bed can also be, avoid sleeping on a soft spring bed. 2, what exercise is good? Physical exercise is very necessary, especially to strengthen the functional exercise of the lumbar back muscles, because appropriate exercise can improve muscle circulation, increase muscle responsiveness and strength, loosen soft tissue adhesions, correct the imbalance between the intrinsic and extrinsic balance of the spine, so as to achieve a good preventive effect. However, it is important to remember to move with a smaller amplitude to avoid other injuries caused by lumbar over-extension and over-flexion (see figure). 3, what activities in daily life are likely to cause lumbar disc herniation? Many patients’ lumbar disc herniation is caused by improper activities or force.
