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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth.
