Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
