Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
