Heat index values are highly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
