Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth.

Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
