Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
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.
