Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
