Heat index values are highly critical to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
