Note: The heat index, also known as 'real feel' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 of high significance 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
