要是睡在床上,床面不能和身体各部位贴实,而且睡着后常觉肩部和髋部有“压麻了”的感觉,一定是床垫太硬了,该换一个软些的。 躺在床上,身体象陷入流沙,翻身或起身时觉得费劲,证明支撑力不够。这样的床,卧时身体不能保持水平,重量大的臀部下陷,使身体两头翘起,腰肌不能松弛,睡醒后腰部酸疼、僵硬、长期将就着睡,会发生腰肌劳损。 If you sleep in bed, the bed can not be affixed with the various parts of the body, but often feel asleep after the shoulder and hip “pressure Ma” feeling, the mattress must be too hard, for a softer. Lying in bed, the body plunges into quicksand and feels strenuous when turning over or standing up, proving inadequate support. Such bed, lying body can not maintain the level of heavy buttocks subsidence, so that the body tilted his head, psoas can not relax, woke up after the waist aching, stiff, long-term will fall asleep, there will be muscle strain.
