Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration.

When body heat isn't effectively managed, risks of dehydration and overheating amplify.
