Note: The heat index, also known as 'feels like', 'felt air temperature', 'real feel', or 'apparent temperature', 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, pregnancy, wind). Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. 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.
