Will A Change in Elevation Affect Breathing?
Well when you move to a higher altitude, there is less oxygen in the air. This is because oxygen molecules are rather heavy and tend to sit at lower altitudes. To compensate for the lack of oxygen (very minor), your body will increase breathing to keep the same level of oxygen in the blood. So for someone in New Orleans, they might be a little less energetic or slightly light headed when engaging in strenuous activity in Denver. However, your body acclimates rather quickly to the new altitude. Going down in altitude has no real negative effect. More oxygen is good!
