Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans.

Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
