Note: The heat index, also known as 'feels like' or 'real feel', comes about by integrating the temperature readings with the humidity levels.

Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
