Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
