Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat.

Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
