A body temperature that is higher than normal because the body takes in or makes more heat than it can lose.

hy-per-THER-mee-uh noun

Word parts

What it means

A raised body temperature that happens when heat builds up faster than the body can get rid of it, as in heat exhaustion and heat stroke, or with some drugs. It differs from a fever, in which the brain resets the body's temperature higher on purpose to fight infection. Heat stroke causes hot, dry skin, a fast heart rate and confusion. Malignant hyperthermia is a rare, inherited reaction to certain anesthetic drugs that makes temperature rise very fast.

For the nurse

Cool the client as ordered (remove extra clothing, cool the room, use cooling blankets, give cool IV fluids) and check the temperature often. Fever-lowering drugs such as acetaminophen do not work well for hyperthermia, because the brain's set point is not raised.

Remember it

Hyper is high, therm is heat: high heat.
