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.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat.
