Note: The heat index, also known as 'apparent temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
