Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
