Why do humans breath fast when they exersice?
Exercising elevates heart rate, and thus blood flow. In order to compensate for the quickly expended oxygen in that pumping blood, we breathe faster to inhale more. Breathing through the nose allows for more oxygen to enter the body than through the mouth, so panting should be avoided when exercising.
