Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
