Note: The heat index, also known as 'apparent temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. 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. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
