Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
