High altitude and heart rate
WebThe effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 metres (6,900 ft) above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. [1] WebThen as the body adapts over time (just a couple weeks) to the new high altitude, it’ll make more RBCs to that of a lifetime high altitude resident. Then when that tourist goes home to sea level, they’ll feel more energetic and can “breathe easier” (not more efficiently - they’re not better at binding O2 than anyone else) because they have so many RBCs but then …
