Note: The heat index, also known as 'feels like' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
