this is called an increased heart rate. Both your breathing rate and heart rate increase due to an increased demand for oxygen in the muscles for respiration to take place. Carbon dioxide build up, caused by consumption of oxygen in muscles, lowers the pH of the blood, which is detected, and hormones are released to increase breathing rate. The increased rate of energy production during exercise often creates more heat than is necessary. This means your body has to somehow release this heat to prevent your temperature from becoming dangerously high. To maintain homeostasis, your body activates the sweating process and vasodilation, which helps remove the heat from your body and release it into the surrounding environment.
