Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
