Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
