Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
