Note: The heat index, also known as 'felt air temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
