Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. 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. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
