Note: The heat index, also known as 'feels like' or 'real feel', quantifies the warmth felt when relative humidity is considered. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
