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 human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
