Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
