Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
