When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
