Heat index

Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. 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. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
