Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
