Why Walking is benefical to your overall health?
My personal point of view
Many people believe that walking is good for improving your overall health condition, why?
my understanding of this is that walking can help the circumfluence of your blood in lower limbs back to your right atrium, and therefore force them to participate in exchange of oxygen through lung circulation.
静脉血压
静脉血压是指静脉血管血压或左右心房不部位的血压,一般右心房(肢体回心静脉血)为5mmHg,左心房(肺部来的动脉血)为8mmHg, 比动脉血压120mmHg-80mmHg低16-24倍。因此,静脉血血流缓慢。
肺部血压:
通常情况下,静息状态的肺动脉压为15 mm Hg ,肺部毛细血管血压增高,则会出现肺部高压,如果血压高出20 mm Hg,会出现肺间质部位水肿,如果高出25 mm Hg则会出现肺积水(水肿)
因此,这种情况决定了你必须通过增加下肢压力迫使静脉血向右心房回流,增加回心血量,促进肺循环。
