Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
