Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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 human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
