Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. 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 cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
