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 innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process.
