Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting 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.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
