Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth.

Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
