Heat index

Remember that heat index calculations are made for conditions in the shade with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
