Note: The heat index, also known as 'real feel' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
