The bed is too soft. When I fall asleep, my back hurts. Is it harmful to my health?

Bad, not conducive to the health of the spine. At present, there is a very popular view that sleeping on a hard bed can sleep better than sleeping on a soft bed, which is more conducive to health, especially for the spine. However, this is not the case. Sleeping on a hard bed is not good for sleep or human health, because the hard bed surface can't meet the needs of human body curve, which will cause serious burden and various injuries to muscles and spine.

No matter which posture is taken, the middle part of the body should sink and the trunk should form an arc, which will overload the ligaments around the spine and increase the physiological curvature of the lumbar spine, which will cause low back pain for a long time; Especially for patients with osteoarthropathy such as lumbar disc herniation and proliferative spondylitis, sleeping in a soft bed for a long time will aggravate the symptoms. In addition, sleeping in a soft bed often makes the muscles trapped in the mattress unable to relax, and the internal organs of the chest and abdomen are easily oppressed and can not get enough rest.

It is obvious that the bed is too hard and soft. The ideal bed should be moderate in hardness, and the cotton pad with a thickness of about 10 cm has the best hardness. Such a thick cotton pad can meet the needs of human body surface curve, maintain the integrity and normal physiological curvature of the spine, and is beneficial to sleep and health.

Besides the hardness of the bed, we should also pay attention to its height. The height of the bed is generally about 40~50 cm, that is, it is better to be slightly higher than the knee of the sleeper. So you don't have to work hard to get into bed. You can stretch your legs and wear shoes when you get out of bed.

The bed should be wider. Generally speaking, its length is 20~30 cm longer than that of the sleeper, and its width is 30~40 cm wider than that of the sleeper, so that it can stretch when sleeping, which is beneficial to blood circulation and fatigue elimination.
