Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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 offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
