Note: The heat index, also known as 'apparent temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
