Relative humidity and human comfort! The body cools itself through- evaporation from the skin- evaporation from the respiratory track- radiation- conduction and convection! When the body is under heat stress (large sources of heatfrom metabolism or external sources), evaporation ofperspiration from the skin is most important coolingmechanism.! But, evaporation slows down when air is close to saturation(high RH).! Thus, we are uncomfortably hot when the RH is high.
