Note: The heat index, also known as 'apparent temperature', 'felt air temperature', 'feels like', or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (metabolic differences, clothing, differences in body mass, height, and shape). Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
