Some people think that sleeping in a slightly hard bed can reduce the pressure and stimulation on the lumbar spine, help stabilize the lumbar spine and alleviate its symptoms. However, experiments have been done, and the comparison between the sleeping hard mattress and the medium strength mattress in relieving low back pain shows that the medium strength mattress can relieve low back pain and improve waist function. Because if the mattress is too hard, it will increase the strength of the hip and shoulder, especially when lying on the side. For a long time, it will cause obvious pain in the neck, hip and shoulder. Under normal circumstances, from the side, the physiological structure of cervical spine presents S-shape. Sleeping on a hard bed will make the waist suspended, and the body can not get support at all, thus aggravating the backache.
in addition, sleeping on a hard bed for a long time can also change the curvature of the lumbar spine and cause lumbar muscle strain. But this does not mean that the soft bed is good, soft bed lack of enough support, simply can not maintain the normal physiological curvature of the spine. When lying on the soft bed, the muscles around the spine will contract together to maintain the normal shape of the spine, which will cause backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache, backache. Especially in the growth and development of children, sleep too soft bed can affect spinal development, leading to spinal curvature and hunchback.
the spine of the body has a physiological curvature, and the mattress is too soft or too hard to fully fit the human body. The mattress with moderate hardness is recommended. This kind of mattress can maintain the natural extension of the spine, fully fit the shoulders, hips and waist, and avoid leaving gaps.
physical weakness and menopause, as well as children prone to sweat when they sleep, sweat will penetrate into the mattress. If the bed permeability is poor, it may breed too many mites and bacteria, leading to moisture invasion in the body, so you need to choose a mattress with good permeability.
the mattresses on the market are divided into spring type, latex type and palm type. The spring type mattress has good elasticity, high air permeability and hardness, and has good supporting property, but it is easy to collapse when it is excessively stressed. Latex mattress has good elasticity and strong air permeability, can adapt to the curve of the human body, and can disperse the average pressure, but it is not suitable for people with poor sleeping posture. Palm mattress has moderate hardness and good flexibility, but it is easy to get moldy and moth eaten.
to sum up, it’s not good if the bed is too soft or too hard. You can choose a mattress with moderate hardness. People who are too thin may feel uncomfortable in hard bed, so soft mattress is recommended. The body is too fat people try to choose a little hard mattress, can make the human body pressure evenly distributed to the mattress. Old people’s bones gradually degenerate, you can choose a slightly hard bed, more fit the curve of the old people’s body. In addition, different people should choose different sleeping positions. Patients with disc herniation can bend their knees to the chest when they sleep, which can open the space between the vertebral bodies and effectively reduce the pressure between the lumbar intervertebral discs. People who are used to lying flat can put a pillow under the knee joint when they sleep, which can prevent excessive pressure on the spine during sleep, and is conducive to adjusting internal organs and spine. You can play with mobile phones during pregnancy, but these four methods of “hurting your fetus” are not advisable. Be careful of the damage to Taibao
