Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
