Why does skin temperature increase as the intensity of exercise also increases?

Answer 1

it doesnt. the oxygen level in your blood increases because you breathe harder to get more oxygen into your body to take to your muscles. look up blood doping though... (its when athletes take blood out of the body and then excercises... and before competitions, the athletes put the blood back in their body so here is more blood to get oxygenated for better performance, even though it is illegal in most sports). =)

Answer 2

Because in order to carry on all of that intense exercise, your body is burning a lot

of fuel. Part of that metabolism becomes useful mechanical energy, the rest becomes

heat, and all of that heat has to be dissipated somehow so that your internal organs

don't become pot roast. Blood carries the heat to the surface, where it dissipates into

the air. If even more heat has to be shed, then sweat begins, in order to take advantage

of the heat lost during evaporation.

Answer 3

When you exercise, your body converts sugars to energy, and this requires oxygen. So, to get more of the energy required during exercise, your muscles need to get more oxygen faster. Oxygen in your body is transported by blood, so your heart has to pump faster to bring the oxygen to your muscles.

Answer 4

During exercise the muscles use more oxygen, this causes more capillaries to open, which allows more blood to return to the heart, which raises the cardiac output.

Answer 5

its cos your heart beats faster, pumping more blood, therefore increasing the rate of blood flow throughout the body, including the brain.

Answer 6

Because exercise dilates blood vessels, and blood flows faster and closer to the skin.
