Note: The heat index, also known as 'felt air temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance 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.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
