Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
