Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
