Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels.

Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
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. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
