During hot and humid weather, we sweat incessantly due to high humidity. But when we sit under a fan, we feel cold and comfortable. Why do we feel cold and chilled? Why don’t we feel the humidity?
Answer
When you switch on the fan, the air of the fan removes or evacuates the water vapour from the nearby areas.So.the place [not large although] becomes void of water vapour...And so when you sit there with sweat, your sweat is absorbed by the apparently dry air of that place.During evaporation, the sweat absorbs the latent heat of vaporization from your body and thus you feel cold...
