Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content.

Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
