A rapid rate of breathing can occur normally after exercise. In addition, panic states and high altitude climbs can also raise the respiratory rate. When these conditions occur, individuals may have a variety of symptoms related to pH changes in their bodies caused by the hyperventilation
Your body needs oxygen to breathe, which it takes from the air around you, into your lungs, to your heart - where it is pumped to your muscles and organs.
