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 the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
