Herniated lumbar discs can not sleep in a soft bed, nor can you sleep in a bed that is too hard, it is recommended to sleep in a soft and hard bed, preferably with the physiological curvature of the spine to fit. Although the soft bed is in close contact with the body and has a good sense of comfort, it cannot support the waist, and under the action of body weight, the soft bed forms a situation of low in the middle and high around the body, which causes the lumbar muscles and ligaments to contract, tense and even spasm, aggravating the burden on the waist, thus aggravating the lumbar disc herniation. Too hard bed and the human body contact area is too small, uneven distribution of support, the lumbar overhang, will also lead to lumbar muscle fatigue, soreness, lumbar spine sustained strain. It is recommended to sleep on a hard board bed, but not directly on the hard board, but on the bed board on the soft cushion, so that the bed is soft and hard, not only can give enough support to the waist, but also a better fit for the waist, so that the lumbar muscles are completely relaxed during sleep, which promotes the recovery of lumbar disc herniation. A medical cushion can be placed under the waist for support if necessary. Sleeping on a hard board bed is not a substitute for treatment, when there is a lumbar disc herniation, you also need to seek medical treatment in time for treatment.
