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

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.
