Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
