Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
