Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
