Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
