Note: The heat index, also known as 'feels like' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
