Lumbar disc herniation is a common orthopedic disease that can occur in all ages, mainly due to degenerative changes in the nucleus pulposus, fibrous ring and cartilage plate, especially the nucleus pulposus, to varying degrees, and under the action of external factors, the fibrous ring of the disc ruptures and the nucleus pulposus tissue protrudes (or prolapses) from the rupture site in the posterior or spinal canal, resulting in irritation or compression of the adjacent spinal nerve roots, resulting in lumbar pain, numbness and pain in one or both lower limbs. or both lower extremities numbness, pain and a series of other clinical symptoms. The incidence of lumbar disc herniation is highest in lumbar 4-5 and lumbar 5-sacral 1, accounting for about 95%. There is a folk saying that sleeping on a hard bed can cure lumbar disc herniation, is it right or wrong? When people lie in bed, can reduce the weight, and weight on the pressure of the intervertebral disc, lumbar muscles, ligaments, joint capsule relaxation, fully relaxed. It helps to release the contraction and spasm of the lumbar muscles and ligaments, restore the original balance of the lumbar muscles and ligaments, and the herniated nucleus pulposus also shrinks, reducing the degree of pressure on the nerve roots, thus relieving pain. For patients with the first onset or acute attack of lumbar disc herniation, absolute bed rest is effective. The more “hard” you sleep on a hard bed, the better? The harder the bed, the better? In fact, the harder the bed is not to sleep on a bare board, hardwood bed, without bedding, but varies from person to person. For elderly patients who are thin, the bed will feel very uncomfortable when the protruding part of the bone is squeezed by the bed board, so you can lay a quilt or mattress of about 3 to 5 centimeters on the bed and adjust the thickness of the quilt according to your situation after slowly adapting. Patients who are fat are suitable for sleeping on a slightly harder mattress, and the quilt can be a little thinner when padded. The human body should maintain the normal physiological convexity of the lumbar spine in the supine position, and keep the lumbar spine from scoliosis when lying on its side. In addition, bed rest is not absolute immobility, can be appropriate exercise in bed, especially functional exercise, can avoid muscle wasting atrophy and prevent nerve root adhesion, is extremely helpful for future recovery from the disease after getting out of bed. Patients with lumbar disc herniation focus on daily prevention to avoid recurrent attacks One: sleep on a hard bed. Sleeping on a hard bed can reduce the pressure on the intervertebral disc. Two: pay attention to the lumbar warmth, try not to get cold. Wear a waist circumference (lumbar belt) during the day to strengthen the protection of the lumbar back, while favoring the recovery of lumbar spondylosis . Three: usually do not do bending and forceful movements (such as dragging the floor …), try to rest in bed during the acute attack, and also after the pain period to ease. Pay attention to proper rest and do not overexert yourself. To avoid aggravating the pain. Four: usually do not bend when lifting heavy objects, should first squat down to get heavy objects, and then slowly get up, try to do not bend.
