Answer:
sweat and vasodilation
Explanation:
Hyperthermia is when the body is too hot. (Not to be confused with hypothermia, when the body in too cold).
When we sweat, we are releasing moisture, like little bits of water, onto our skin. The water uses up heat energy from the body to evaporate. Because the body loses heat energy, it cools.
Vasodilation is when blood vessels widen. When this happens, the blood vessels are closer to the surface of the skin, allowing heat to escape through and exit the body.
Shivering and vasoconstriction would help to keep a person warm. Shivering makes the muscles on the body move, which increases heat. (Think of exercise, but on a small scale).
Vasoconstriction keeps blood vessels away from the surface of the skin.
