Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat.

Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
