Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body.

With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
