Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
