Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels.

In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
