Heat index values are particularly relevant to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. 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. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
