It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
