Note: The heat index, also known as 'feels like' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth.

It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down.
