The human body emits electromagnetic radiation in the form of thermal radiation, commonly referred to as body heat. This radiation falls within the infrared region of the electromagnetic spectrum.
The wavelength range of thermal radiation emitted by the human body typically spans from approximately 5 micrometers (µm) to 20 micrometers (µm). This range corresponds to the mid-infrared region.
The average wavelength of photons emitted by the human body is around 10 micrometers (µm). It's important to note that the exact wavelength distribution may vary depending on factors such as body temperature and the specific area of the body being measured.
