Note: The heat index, also known as 'real feel' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
