在我国有些地方,人们习惯蹲在地上吃饭,特别是农村,每逢吃饭俩一伙,仨一群地蹲在地上,一边吃饭一边谈笑,觉得挺有意思。其实这是最不好的姿势,有损身体健康。其一、腹部受挤压,胃肠蠕动受到限制,影响食物的消化和吸收; 其二、胃肠受压而不通畅,有了气体排不出去,造成胃腹胀满不适,影响食欲; 其三、由于腹部和大腿部分较长时间受挤压在一起,造成部分血管受阻,使胃壁得不到充足的血液供应。而进餐时正是胃紧张工作需要较多血液来进行消化的时候。久而久之可引起慢性胃病。大腿受压容易造成麻木; 其四、蹲的时间长了,血液在下肢回流不畅,影响全身血液循环。站起之后会造成大脑暂时性供血不足,使人头晕、眼花。再加上下肢麻木,容易摔倒。
