Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. 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. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
