Note: The heat index, also known as 'apparent temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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 is essential for the human body; it facilitates cooling through the process of sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
