People with bad waist is best to sleep on latex mattresses, for two main reasons: 1, latex mattresses have a very good shaping effect, after people lie on the mattress, in line with the normal physiological curvature of the human lumbar spine, the soft tissues around the waist will be able to fully in a relaxed, resting state, to avoid fatigue. Normally, if you sleep on a hard bed or too soft mattress, it may lead to the disappearance of the normal physiological curvature of the waist, resulting in the surrounding muscles and the surrounding soft tissues show tension, fatigue, time will lead to strain around the soft tissue, but also easy to form local inflammation, hyperplasia, bone spurs, calcification and other abnormal performance, will aggravate the pain of the waist, resulting in more obvious symptoms of the waist. May lead to local hyperplasia tissue, the surrounding nerve structure stimulation, lower limb numbness or radiating pain-related symptoms. 2, latex mattress has a very good breathable effect, will not appear locally due to poor ventilation, resulting in the formation of local sweat, sweat in the process of evaporation, easy to appear local cold. Once the cold will lead to decreased blood circulation, muscle tissue will become more tense, which will lead to the gradual accumulation of local metabolic products, increased, the peripheral nerve stimulation and pain.
