Note: The heat index, also known as 'feels like' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content.

Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body.

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