Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
