Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 extremely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
