Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
