The heat of vaporation makes us dehydrated and that can cause nausia and even death. Fans keep our bodies cool so we dont get heat stroke

During conversion of water into gaseous state(vaporisation) the heat of the system becomes constant till all water gets converted into vapour.This undetectable heat is called latent heat of vaporisation.This is because the heat is being used up for breaking the bonds between particles so as to convert them into water vapour.
During summer season sitting under the fan makes us comfortable because the wind takes away the water vapour present in the air with it.This allows more water vapour to enter the air.Therefore evaporation takes place faster and this leaves our bodies cool.
