Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
