Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
