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

Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced.
