Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation.

Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
