The benefits of swimming for lumbar disc herniation are as follows: 1. Accelerate blood circulation throughout the body: especially the low temperature of the water will stimulate the body, which can make the blood circulation speed up significantly, so that the local inflammation caused by lumbar disc herniation can be absorbed, thus relieving the pain symptoms. 2. Exercise the strength of the lumbar back muscles: because swimming is a non-weight-bearing activity, it does not increase the pressure on the lumbar discs while exercising, so it is good for The lumbar intervertebral disc protrusion does not stimulate the symptoms, but will make the lumbar back muscle strength, improve the stability of the lumbar spine, and help control the further development of the lumbar intervertebral disc protrusion.
