Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important 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 physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
