Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation.

Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
