Why does your temperature go up during exercise?

Answer 1

Like everything else, your body isn't 100% efficient in it's conversion of energy to useful work. As you convert food to energy to do useful work, some energy is lost in the form of heat. This heat causes your temperature to rise.

Answer 2

Exercise causes a stress response in the body, which activates the sympathetic nervous system. This diverts blood away from the digestive system through vasodilation, sending it to the muscles instead. When you exercise, the mouth, being part of the digestive system, has blood diverted from it, leading to an apparent drop in body temperature if you are taking an oral reading.

Answer 3

The body's temperature rises after exercise because the body is producing energy through use of muscles. Light exercise does not cause a rise in body temperature.

Answer 4

body temperature increases after exercise
