Note: The heat index, also known as 'feels like' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. 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. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
