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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling.
