Note: The heat index, also known as 'apparent temperature' or 'feels like', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
