I can't sleep in a soft bed, so I can only sleep in a hard bed. I don't know what's going on.

The soft bed makes the whole body sink into the bed, the bones bend, and the strength of each part is different. The spine and muscles can withstand pressure for a long time, which is similar to keeping a posture still. But the hard bed makes the muscles and bones of the whole body stable and natural, and is not affected by physical pressure.

Therefore, it is recommended that you sleep on a hard bed, which can effectively relieve fatigue and help spinal diseases.
