Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
