Patients with lumbar disc herniation have no requirement for pillows when they sleep, but they are required to lie absolutely flat on a hard bed, so it is best not to sleep on latex pads. Patients with lumbar disc herniation choose to sleep on a hard bed in order to maintain the normal shape and physiological curvature of the spine, it is generally believed that adults in 20 years of age after the lumbar intervertebral discs began to undergo degenerative changes in the elasticity of the intervertebral discs and resistance to the load and the consequent decline in the ability. Lumbar intervertebral discs bear the weight of the body in daily activities, and the back of the annulus fibrosus of the intervertebral discs will bear the greatest pressure in human lumbar activities. If you keep stimulating the area, it will easily lead to cracks in the annulus fibrosus, and ultimately make the annulus fibrosus become weak. If the weak annulus fibrosus undergoes a heavy lumbar trauma or repeated minor injuries to the lumbar region, or if there is a sudden increase in weight bearing in daily life, resulting in an increase in the pressure on the lumbar intervertebral discs, the annulus fibrosus can be ruptured further, resulting in a decrease in water content, and degenerated nucleus pulposus tissue protrudes from the ruptured area, resulting in low back pain.
