Heat index values are highly critical to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
