Note: The heat index, also known as 'feels like' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth.

Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
