Note: The heat index, also known as 'feels like' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 are extremely significant for babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. 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.
