Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
