Note: The heat index, also known as 'real feel' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
