The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth.

Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
