Heat index values are highly critical to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
