Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics.

Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
