Question

Which type(s) of electromagnetic radiation do human bodies emit? Which type(s) can our senses detect?

Answer 1

Parts of our body (eyes) function as pretty good detectors for
electromagnetic radiation in the visible-light band.

Nerve endings in our skin operate as detectors for radiation in
the heat band, and our bodies as a whole transmit radiation in
the heat band.

Skin pigment also responds to stimulation by ultraviolet radiation,
but that happens much more slowly.
