1. can better maintain the lumbar spine in a physiological lordosis posture, relieve the excessive stretching of the lumbar muscles caused by fatigue during the day, ensure the relaxation of the lumbar muscles, get adequate rest at night, and consolidate the achieved curative effect.

2. After the relaxation of the psoas muscle, the local blood circulation is also improved, which is conducive to the gradual tissue repair of the tense psoas muscle, enhancing muscle strength and muscle tension, and is conducive to the next day's activities.

3. For the compression fractures of lumbar vertebrae and lower thoracic vertebrae, the lumbar pillow can also promote the gradual reduction of fractures and relieve traumatic low back pain.

4. Patients with lumbar disc herniation often put pillows under the waist, which can widen the intervertebral space and reduce the pressure on the intervertebral disc. Some can also accommodate intervertebral discs, eliminate the compression on cauda equina and nerve roots, and then relieve low back and leg pain.

5. Gradually restore and enhance the dorsal extension ability of dorsal muscles, especially sacrospinous muscles, and the toughness of supraspinous and interspinous ligaments, so that the waist can be strongly stretched, standing for a long time, and stabilizing the spine.
