Default 为什么右侧卧的睡姿是最科学的

  中国青少年研究中心青少年儿童所助理研究员赵霞介绍说,当一个人仰卧时,背部肌肉不能得到很好的放松。 这是因为仰卧时身体的重量都压在背部,使得背部肌肉过度受压,因此人们往往在睡了一个夜晚起床之后,还会背 部疼痛。而且,仰卧时,由于舌头是软体的,在口腔中往往会向咽部低垂,这样很容易引起呼噜,口水也更容易流 入气管引发咳嗽,健尔马足疗机厂家。我们常常看到有的人仰卧睡觉,睡着睡着突然咳嗽起来,就是这个原因。此外,仰卧睡眠两手常常会放在胸上, 这样还容易做噩梦。
当俯卧睡眠时,身体和腿部肌肉并不能完全放松,胸部和腹部的肌肉会受到压迫,使心脏和肺部不能得到很好的休 息,而且俯卧时头部也常常会陷到松软的枕头里,这样呼吸也会受到很大影响。另外,因为长时间把脖子扭向一边 ,可能会导致落枕,使颈部肌肉扭伤。因此,比较而言,侧卧是比较好的姿势,可以避免上述情况发 生。
  专家指出,侧卧时,脊柱多向前弯成S型,四肢容易放在舒适的位置上,可以使全身肌肉得到放松。之所以选 择右侧卧,是因为心脏在胸腔内偏左的位置,如果采取左侧卧的姿势,会使心脏受到压迫。右侧卧睡时心脏受压少 ,胃通向十二指肠以及小肠通向大肠的口都是向右侧开,有利于胃肠道的正常运行。此外,肝脏也位于右上腹部, 右侧卧位时它处于较低位置,血液可以更多地供应肝脏,这样有利于消化食物及代谢体内营养物。因此,保持右侧 卧位对身体健康更有好处。
