Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
