Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
