The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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 primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
