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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration.

Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
