Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
