As sweat vaporizes, the energy to achieve this has come from the hotter body. The net result is a cooling effect, and the surface temperature of the body decreases.
The rate of evaporation depends on the surface area, the temperature difference, the humidity and, therefore, the difference in vapour pressure, the rate of sweating and the velocity of air flow.
