Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 remain especially vital for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
