Note: The heat index, also known as 'feels like' or 'real feel', determines the feeling of heat when you account for the relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
