Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
