Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
