Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. 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. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
