Note: The heat index, also known as 'apparent temperature', 'feels like', 'felt air temperature', 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 (wind, pregnancy, metabolic differences). Be aware that direct exposure to sunlight increases heat impact, and may raise the heat index additionally, by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. 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.
