It is ok to put a pillow under your waist when you sleep, which has many benefits. Putting a pillow under the waist is more in line with the physiological bending of the human body, which can relax the lumbar muscles better, relieve the fatigue of the lumbar muscles during the day and get a better rest.

Relaxing the psoas muscle is also beneficial to the blood circulation of the waist, which is more conducive to the repair of the strained psoas muscle. It can also enhance the muscle strength and muscle tension of the waist, and put a pillow under the waist to sleep. It is very beneficial to patients with lumbar compression fracture, which can relieve low back pain and promote the healing of lumbar fracture. For patients with lumbar disc herniation, sleeping in this way can enlarge the lumbar space, reduce the pressure on lumbar muscles, relieve low back pain and make people sleep more comfortably at night.

But this method is not a treatment, and serious patients still need to go to the hospital for formal treatment. It is suggested that normal people should put a pillow about 10cm high when sleeping on a hard bed, which can relax the lumbar muscles and relieve fatigue.
