Each breath does two things for our body. It expels carbondioxide when we exhale, and takes in oxygen when we inhale. It’s a delicate balance.Exercise or stress increases the production of carbon dioxide, so we breathe faster to eliminate it and take in more oxygen at a greater rate. Because of the effects of gravity, the amount of air containing oxygen is greater at sea level. For example, he pressure at sea level is twice that found at 18,000 feet MSL.
