That's UV, visible and near IR. We know that 100-600 nm (infrared EDIT: UV) light "can carry out photostimulation and photobiomodulation effects particularly benefiting neural stimulation, wound healing, and cancer treatment" [1]. I'm curious what could be producing UV and visible light.
Does light production tend to hang out around any particular organs or organelles? If stress causes it, I'd hypothesise it's metabolic or signalling related.
Ultraviolet, you mean.

There is tons of chemoluminescent stuff in a live being. As my spectroscopist friend says, everything luminesces at some point.

You can see it in the picture, the radiation is very wide.
The thinking that preceded our current understanding of physical elements was very loose and woo-woo(Water, Earth, Wind, Fire), but we refined.
So probably invisible but under the very darkest of conditions?
