Note: The heat index, also known as 'feels like' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception.

Heat index values are especially crucial for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth.
