Note: The heat index, also known as 'real feel' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 particularly important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
