Heat index values are especially crucial for 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
