Note: The heat index, also known as 'felt air temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
