Note: The heat index, also known as 'apparent temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
