Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
