    When the water or sweat evaporates it takes heat with it.

    Think of it as the sweat or water leaving and taking the heat with it..

    When a liquid evaporates it needs to acquire potential energy to change from a liquid to a gas.

    This is stored as heat.

    This heat does not create a rise in temperature.

    This heat is known as latent heat.

    Usually you heat a kettle and the water boils.

    This is putting potential energy into the water, it then boils.

    When water evaporates , it takes heat from its surroundings to do so.

    The effect of taking heat out of the surroundings is that the surroundings cool down.

    Therefore evaporation has a cooling effect on things.
