Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling.

Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
