Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
