Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
