Increased respiration
Increased respiration also known as tachypnea is a cardiovascular response to the lungs to increase breathing so that the heart can receive more oxygen. With the rapid output of energy the body compensates by circulating more blood with oxygen, glucose and other essential cellular molecules to increase the bodies pace. Increased respiration can also be caused if the body lacks oxygen for an elongated period of time, in which the body needs to return to baseline so it compensates.
This effect is most noticeable in stimulating substances since the body needs to compensate for the accelerated energy output.
