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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
