Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception.

Heat index values are highly critical to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
