Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
