Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling.

If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
