We Emit a Visible Light That Vanishes When We Die, Says Surprising New Study
- In 2009, a team of scientists affiliated with Canadian institutions conducted experiments measuring ultraweak photon emissions from entire mice and various plant leaves under different experimental conditions.
- They aimed to determine if UPE intensity, linked to cellular metabolism, changed when scaling from tissues to entire living organisms and if it ceased upon death.
- Using electron-multiplying charge-coupled device cameras, the team imaged four mice alive and after euthanasia, showing UPE rapidly declined postmortem and increased in injured plant leaves.
- The researchers observed that damaged areas of all leaves emitted noticeably more light compared to the intact regions throughout the entire 16-hour imaging period, suggesting that stress increases photon emission.
- These findings suggest non-invasive monitoring of UPE could track health or stress in humans, animals, crops, or bacteria before visible damage manifests.

Living Things ‘Glow’ With an Invisible Light, Calgary Researchers Find
Humans may be luminous beings—literally—according to researchers at the University of Calgary who authored a new study. Examining mice and plants, the researchers in a cross-disciplinary study found tiny amounts of light are being emitted from living specimens as part of their metabolism. The study suggests all lifeforms, including human beings, have a similar “glow” that seems to diminish upon death. Daniel Oblak, an associate professor at the …


Humans 'emit mysterious light that disappears when we die,' say scientists
HUMANS do actually glow with health, according to scientists, as a new study suggests our bodies emit an extremely faint light that goes out when we die.

Humans give off a ghostly glow that vanishes when we die
The light is too dim for humans to see (Picture: Getty) All living things – from humans to mice and plants – emit a ghostly glow up until they die. Mystics and holistic medicine practitioners have long claimed to see a mysterious aura around people. But for what might be the first time, scientists say they have seen this glow, too. This glow, a new study found, is too faint to be seen and goes off once creatures die. Researchers say that the fai…
Humans give off visible light that vanishes when we die, new study shows
It turns out the idea that humans glow might not just be poetic. A new study from the University of Calgary and the National Research Council of Canada has captured physical evidence showing that living organisms, including mice and plants, emit a faint visible light that vanishes upon death. This barely-there glow, known as ultraweak photon emission (UPE), is produced by chemical reactions inside cells. While these biophotons are far too dim fo…
