Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel.

Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
