Heat index values are typically calculated for conditions of shade and a light breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
