After a day at work, after squeezing the bus and subway home, half-lying on the sofa or bed playing with your phone and listening to ** is the most comfortable thing. But you know what?When lying half-lying, the lumbar spine will lack sufficient support, change the original curvature, increase the gravity of the lumbar intervertebral disc, and even induce lumbar intervertebral disc herniation.
For people with a healthy lumbar spine, the lumbar spine has a normal physiological curvature. Under normal circumstances, the force point of the lumbar thrust joint is generally at waist 45 and sacrum 1. When lying flat, the lumbar disc is under minimal pressure. When semi-lying, the waist is suspended and the lumbar spine is folded and unsupported. The weight of the upper body is completely pressed on the stress point of the lumbar vertebrae, and the muscles and ligaments are in a relaxed state when lying half-lying, losing the original fixation, the spine is deformed, and the physiological curvature becomes straight, which will cause lumbar disc herniation over time.
1. Sitting for a long time hurts the waist the most: When sitting for a long time, you should get up and move your waist after a period of time. If you can't get up, you can also sit and do lumbar stretching activities to avoid lumbar spine strain caused by overexertion.
2. Shoulder backpack: If your backpack is only carried to one side of the shoulder for a long time, it will lead to high shoulders and low shoulders, because many muscles attached to the shoulder bones are connected to the spine, so the shoulder height will cause scoliosis and pelvic tilt, which will damage the lumbar spine.
3. Bad behaviors: Sometimes bad behaviors, such as leaning forward when doing housework or washing, and suddenly moving heavy objects when bending over, can also damage the lumbar spine and cause lumbar disc herniation.
