Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat.

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