Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat.

Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
