Your Body Gives Off a Glow That Fades When You Die, According to New Research

Science has long dismissed ancient mystic’s claims of an “aura” emanating from life forms as pseudoscience. But new research from the University of Calgary and the National Research Council of Canada sheds new light on life. Their study, published in The Journal of Physical Chemistry Letters, reveals that all living things emit faint light. This faint light, including that from humans, vanishes at the exact moment of death, according to their findings. Scientists have called this phenomenon ultraweak photon emission (UPE), or biophoton emission.

The Science Behind the Glow

Unlike the spectacular bioluminescence observed in fireflies or deep-sea creatures, the light emitted by living organisms is so faint that it is hidden to the naked eye. Ambient electromagnetic waves conceal the visible wavelengths of light that biological processes emit, even in theoretical conditions. While faint on their own, ambient electromagnetic waves and metabolic radiance dim this “glow,” making it difficult to track accurately. Environmental electromagnetic waves and metabolic light emissions reduce the visibility of this faint glow from living organisms. These overlapping emissions complicate the detection and measurement of biophoton signals across entire organisms.

Scientists have detected this subtle glow in many life forms, including bacteria, plants, animals, and humans alike. This ultraweak photon emission falls within the spectral range of 200 to 1,000 nanometers, spanning ultraviolet to near-infrared wavelengths. The source of this light lies deep within our cells. As our bodies metabolize food and oxygen to produce energy, they generate reactive oxygen species

These are highly reactive molecules that if left to build-up, can damage cellular components. Cells stressed by heat, toxins, pathogens, or injury increase reactive oxygen species levels, triggering a cascade of chemical reactions. Some of these reactions excite electrons, causing them to release photons as they return to their resting state.
