Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. 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.
