Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Rising body temperatures due to excess heat retention could signify impending heat disorders.
