When a brain is alerted to a sudden decline in oxygen, your brain undergoes certain changes that contribute to the perceptual distortions that accompany a near-death experience. With the heart unable to pump properly, oxygen is unable to travel to the rest of the body, which is essential for every single cell in your body to survive. This is because people with cardiac arrest have decreasing blood pressure, she says. “About a quarter of people who suffer and survived cardiac arrest have memories about some aspect of near-death experience, Borjigin says. Often, though, people with cardiac arrest will recall near-death experiences. “Like a flip of a switch, you can literally throw somebody out of their body and back into their body,” Nelson says.

Research has shown that direct electrical stimulation of a brain area normally inactive in REM sleep can provoke an out-of-body experience.

While some people may attribute this to a spiritual experience, this is actually a sensory deception caused by the brain, which scientists have successfully replicated in people who are asleep. Of the four, people often recall supernatural activity, particularly the feeling of detaching from a physical body.Ībout 76 percent of people report an out-of-body experience during a near-death experience. Research shows that near-death experiences come in four types: emotional, cognitive, spiritual and religious experiences, and supernatural. In fact, 1 in 10 people have reported sharper senses, slowed time, out-of-body sensations or other features associated with near-death, despite not being in grave danger.

Unreal recallĪ near-death experience can happen to anyone. “The research not only benefits our understanding of consciousness, but also in understanding the importance of the heart, lung, and brain in our everyday physiology,” says Jimo Borjigin, an associate professor of neurology at the University of Michigan Medical School. It could also potentially save lives, because doctors would have more knowledge for when to continue resuscitations after a patient’s heart stops. One goal is to better understand how cardiac arrests happen. One thing is certain: medical experts say near-death experiences are not a figment of the imagination.Īnd figuring out the mechanisms behind this phenomenon goes beyond general curiosity. People who have survived these close calls say the encounter can be life-changing. There’s still a lot of mystery when it comes to the cause, but the field is progressing thanks to people who have allowed scientists to study their brains in these situations. It’s a paradoxical situation, says Kevin Nelson, a professor of neurology at the University of Kentucky: A few perceptions are common-a shining light, for instance-but the near-death experience is unique to each individual. Some have even reported spotting the Grim Reaper by their bedside. They often mention seeing bright lights, their life flashing before their eyes, or visions of deceased loved ones. One big problem almost always gets in the way: How do you ask people what dying feels like when they’re no longer here?īecause we haven’t yet figured out how to communicate with the dead, the best-case scenario is talking to people who have had a close brush with death. Sci-fi author Brian Herbert once wrote, “The only guarantee in life is death, and the only guarantee in death is its shocking unpredictability.” These words ring true to researchers who investigate what happens in a person’s final moments-and the frustration that comes with these studies. Many people resuscitated after cardiac arrest will recall near-death experiences.
