What is a coolant?

A coolant is a medium, usually fluid, used to draw heat from an object.

Sweat is a natural fluid from the body that exits the body through pores in the skin usually due to physical stress and/or high temperature for the purpose of regulating body temperature.

Large amounts of heat are needed to evaporate water, because hydrogen bonds need to be broken, therefore, sweating is an example of using water as a coolant.
