Children typically face more danger than adults as their sweat production is usually lower.

The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
