Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
