when we are sitting under a fan and perspiring the water(or sweat) get's evaporated faster than usual(because of the fan)
why:
this is due to the reason that evaporation occurs ,the liquid (sweat in the case) absorbs heat from the surroundings in order to evaporate .Thus, it takes a lot of heat from your body as well .your body thus become cool.
this happens even when the fan is switched off. but with the fan switched on, the effect can be felt in a better (and cooler)
