Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing.

Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
