If infrared light is a type of radiation emmited by atmospheric molecules how is it that the human body ‘glows’ so much more than its surroundings?

Infrared “light” is heat. It is energy generated in that portion of the electromagnetic spectrum where the wavelengths are longer than visible light. The body radiates heat as a result of regular bodily functions.
To my knowledge the body does not radiate on other portions of the spectrum such as visible light like fireflies.
