Note: The heat index, also known as 'feels like' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
