New study suggest Near Death Experiences likely caused by CO2.

A new study suggest that too much CO2 in the blood during heart attacks is the likely cause of the so-called Near-Death Experience:

In the new study, researchers investigated whether different levels of oxygen and carbon dioxide—the main blood gases—play a role in the mysterious phenomenon.

The team studied 52 heart attack patients who had been admitted to three major hospitals and were eventually resuscitated. Eleven of the patients reported near-death experiences.

During cardiac arrest and resuscitation, blood gases such as CO2 rise or fall because of the lack of circulation and breathing.

“We found that in those patients who experienced the phenomenon, blood carbon-dioxide levels were significantly higher than in those who did not,” said team member Zalika Klemenc-Ketis, of the University of Maribor in Slovenia.

The article goes on to mention that other factors such as age, sex, religious belief, drugs used during resuscitation or how long it took to revive them had no impact on whether or not patients reported an NDE.

The study didn’t speculate on how excessive CO2 would result in an NDE, just that it appears to be the cause. This isn’t too surprising given the fact that people at high altitudes without a pressure suit or who have inhaled a lot of CO2 report NDE-like effects as well.

It’s certainly not conclusive yet, but it is a good start into investigating the phenomena.

  1. So what you’re saying is, more C02 in my blood helps God take me to heaven? Good to know.

    Hmm, what did I do with that syringe?

  2. I always wondered what the real cause was for me seeing that bright light when near to death & that actually makes very good sense. Thank evolution for science & nut cases for religion.

  3. It’s a continuation of “supernatural explanations for things that have natural explanations.”

  4. Don’t forget about naturally-occuring DMT in the brain. It is also found to flood the brain in such circumstances.. DMT of course is a tryptamine similar in structure to serotonin and is a powerful chemical that acts as a hallucinogen.

  5. Thank evolution for science & nut cases for religion.

    Now that CO2 has been declared a “pollutant” by the California Air Resources Board and they can begin monitoring how much we all exhale, I’m sure the government will get a handle on the amount of CO2 occurring naturally and we will have less of these pesky NDE’s. 😉
