Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
