The light of someone's life might not be just another person, but light in the literal sense. According to a recent study by researchers from University of Calgary, every living system emits light without requiring external excitation due to a biological phenomenon known as ultraweak photon emission (UPE).

      No, because the control was a non-living body at the same temperature, and blackbody radiation is a function of temperature alone.

      The results revealed that despite both groups having the same body temperature of 37°C, the live mice showed robust emissions, whereas the UPE from the euthanized mice was nearly extinguished.

      Blackbody radiation starts emitting around 500 C… this is something else I think. In the interest of science though, why don’t we experiment? Let’s heat Elon Musk to 500 C and see what color he glows?

      Living things emitting Infrared radiation? Never heard of it.

      Though I want to say singlet oxygen reactions let off light in the red part of the spectrum.
