Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
