Note: The heat index, also known as 'feels like' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
