Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances.

Heat index values are highly critical to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
