In-depth understanding of near-death experiences

Near-death experience is an increasingly popular topic, especially after popular movies and books about the out-of-body experience and other feelings that people experience in life-threatening situations. Of particular interest are the two books written by doctors on near-death experiences.

For example, in “Proof of Heaven,” Dr. Eben Alexander recounted his experience in a coma due to meningitis for a week. Meanwhile, in “To Heaven and Back”, Mary C. Neal discussed her dying experience when she was submerged in a river after a kayaking accident.Both books took quite a bit of time New York Times The bestseller list shows that this topic not only arouses national interest, but also requires more research from the medical community.

After experiencing a near death experience, Dr. Alexander studied his medical records and concluded that he was in a deep coma and his brain was completely shut down. He believed that the only way to explain what he had experienced was to accept that his soul had left the body and went to another world.

What is a near death experience?

From bright lights and warmth to detachment from the body, flashbacks, and encounters with angels and other lives, these are the experiences told by people who have experienced near-death experiences. More importantly, people who have had these experiences report that their experiences were neither dreamlike nor hallucinations, but more real than real life itself.

Although these near-death experiences are recognized phenomena, many people still question the validity of near-death experiences. For critics, stories about near-death experiences or out-of-body experiences are sometimes referred to as soul power, hoaxes, alien abductions, and other stories.

For many people, the near-death experience is simply unbelievable. However, these experiences are too much and well documented to be completely fabricated.

Popular theory

The brain is complex and delicate. For example, if oxygen is reduced or even small, the brain will respond almost immediately. Therefore, many scientists believe that near-death experiences are the result of physical changes in the brain, such as brain stress or hypoxia during death.

Oxygen loss

They believe that these experiences are caused by hypoxia, anesthesia problems, and the body’s neurochemical response to trauma. But those who said they had near-death experiences said that these explanations were inadequate, and they did not explain or even approached acknowledging their experiences.

Obviously, the near-death experience is both interesting and scientific. In addition, with advances in medical skills and technology, doctors are now able to bring people back from the brink of death more frequently. Therefore, descriptions of near-death experiences seem likely to increase.

Survive Adversity

For example, there are reports that people recover completely after hours without breathing or pulse, being buried in snow, or immersed in extremely cold water. In fact, surgeons even deliberately create these conditions. Not only did they cool the patient’s body or stop their heart from performing dangerous operations, but they also began to try these techniques on severely injured trauma patients. They let them wander between life and death until their wounds are fully repaired.

Anesthesia awareness

Therefore, people usually have a story to tell their experience. Many times, doctors often attribute these out-of-body experiences to “anesthesia awareness”, and they say that about one in every 1,000 patients is affected by this. When the patient is under anesthesia but can still hear the conversation fragments or hear the music playing in the operating room, anesthesia consciousness will appear.

What the research says

The first written records of near-death experiences can be traced back at least to the Middle Ages, and some researchers insist that they can even be traced back to ancient times.Actually Medical Journal recovery Published a brief description of the oldest medical description of near-death experiences written by French military doctors in the 18th century. However, it is said that most modern research on near-death experiences began in 1975.

Researchers at the University of Southampton

Although there are few objective studies on near-death experiences, there are some studies that provide preliminary insights into these experiences. For example, researchers at the University of Southampton conducted a four-year international study of more than 2,000 cardiac arrest patients.Their results and preliminary conclusions are published in recovery.

In this study, called AWARE (Awareness During Resuscitation), researchers studied a wide range of consciousness and psychological experiences associated with cardiac arrest. Of the 2,060 patients participating in the study, 330 survived, and 140 were able to complete structured interviews about their memory of the event.

Consciousness and memory

Researchers found that nearly 40% of them described some knowledge about the time before resuscitation or when the heart stopped beating. Nevertheless, most of these patients do not have any specific memories of this event. This shows that many people do have mental activity during cardiac arrest, but often lose the memory of this activity after recovery. According to the doctor who conducted the study, this may be due to brain damage or sedative drugs.

For example, it is well known that ketamine is a drug commonly used for sedation and general anesthesia. It can make people feel strongly separated from the body and feel peaceful or happy. In fact, the calm state they experience with ketamine is often very similar to the near-death experience.

Interestingly, the study also found that 46% of people’s memories of death are inconsistent with the way people describe their near-death experiences. In fact, some people report that they are afraid or feel that they have been dragged deep into the water. Only 9% of people have experiences similar to near-death experiences, and 2% have experiences of out-of-body experience, including hearing and seeing events.

Patient experience

In the case of one patient, consciousness and consciousness appeared to occur within three minutes of no heartbeat. The researchers found this finding to be contradictory because the brain usually stops functioning within 20 to 30 seconds after the heart stops and does not seem to recover again until the heart restarts. Therefore, there may be some facts of brain activity indicating that something is happening.

Overall, researchers cannot deny that near-death experiences will definitely happen. Similarly, there is a group that reports experiences that they are unable to determine the reality or significance of the patient’s experience.

Patients believe that terms such as near-death experience and out of the body may not be sufficient to describe the actual experience of death and what is happening in the brain.

Finally, they suggest that future research should focus on cardiac arrest, which is biologically synonymous with death, rather than the medical state sometimes referred to as “near death.”

George Washington University Research

At the same time, another study examined the brain activity of seven critically ill patients who were out of the life support system. Researchers used electroencephalograms to record neural electrical activity and found that neural activity peaks at or near death, even if blood pressure drops and brain activity drops before the peak.

According to researchers, these spikes occur when we most think the brain is dying due to insufficient blood flow. Soon after the brain activity ceased, the patient was declared dead.

Researchers speculate that as blood flow slows and oxygen is depleted, cells can no longer maintain a charge. What happens next is a series of activities that create ripples in the brain. If these “seizures” occur in the memory area of ​​a person’s brain, this could explain the vivid memories people report during resuscitation.

Very good sentence

For many years, stories of near-death experiences and out-of-body souls have attracted people from all over the country. In fact, people like to hear what others have witnessed when they are on the verge of death. However, there is still a lot of content about near-death experiences that can neither be understood nor explained. Obviously, additional and real research is needed around near-death experiences and out-of-body phenomena. Before that, many people were comforted by knowing that these experiences are part of life itself.
