Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
