When the core temperature of the body rises above normal, nerve impulses from the brain's thermo-regulatory center, the hypothalamus, stimulate the sweat glands to produce sweat which is then poured out onto the skin.
The cooling effect takes place when the water content of the sweat, evaporates from the skin by use of the latent heat of vaporization. Since water has a high latent heat of vaporization (that is it requires a high amount of energy in the form of heat to convert to vapor), it leaves behind a cooling effect on the skin. This happens when the water in sweat evaporates and in the process takes away heat from the body necessary for its evaporation.

Answer:
When we get sweat,the droplets of sweat evaporates from the surface of our body by absorbing the heat from our body.
Thus the particles of liquids (sweat) extract energy from our body and and escapes into the surroundings.
As the energy from our body is is lost in the form of heat energy, the body becomes cool and we feel comfortable.
