Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off.

If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
