Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
