Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
