Note: The heat index, also known as 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely 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 body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
