(1)易致脊柱的位置失常

  孕妇的脊柱较正常人的腰部前屈更大,睡席梦思床或沙发床,会对腰椎产生严重影响。仰卧时,其脊柱呈弧形,使已前屈的腰椎小关节磨擦增加;侧卧时,脊柱也向侧面弯曲。长此下去,孕妇易感到疲劳,而且还会使脊柱椎体关节窝的位置失常,压迫神经,增加腰肌的负担,既不能消除疲劳,又不利于生理功能的发挥,并可引发腰痛。

(2)不利于翻身

  正常人睡觉时睡姿常常变动,1夜辗转反侧可达20~26次,翻身有助于大脑皮质抑制的散布,提高睡眠质量。但是,孕妇睡席梦思床太软,身陷其中,不容易翻身。同时,孕妇仰卧时,增大的子宫压迫腹主动脉及下腔静脉,致使子宫供血减少,对胎儿不利,乃至出现下肢、外阴及直肠静脉曲张。右侧卧位时,上述压迫症状消失,但胎儿可压迫孕妇的右输尿管,易患肾盂肾炎;左侧卧位时上述弊端可避免,但可造成心脏受压、胃内容物排入肠道受阻,一样不利于孕妇健康。

因此,孕妇不宜睡席梦思床,睡棕垫床或者在硬床上铺9厘米厚的棉垫。
