Note: The heat index, also known as 'felt air temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
