Note: The heat index, also known as 'apparent temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
