Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. 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 hold particular importance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
