Note: The heat index, also known as 'feels like' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
