Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature.

Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
