See what is at the moment of near death?

Perhaps not at least once in my life, most of us have asked ourselves what it would be like to die. How is that feeling? Those who unfortunately suffer from cardiovascular diseases, have experienced a "clinical death" , can give you that answer.

The story begins with a man named Joe, when he remembers the moment when everything sinks into darkness and sees a strange light. That light led him to a field of flowers and met some white bearers talking to him about his future. The next thing Joe remembered was that he was awakened after going through all those things, and suddenly realized he was lying on the emergency table with the doctors around him, trying to rescue Joe's heart. beat again.

You may have heard a lot of similar stories, and what Joe experienced was called near-death experience (NDE, "NDE"). According to Callaway, about 10 to 20 percent of heart attack survivors have experienced this "clinical death" experience . Normally, when falling into this state, people often feel suspended, or find themselves walking in a tunnel, following a strange light, walking on cloudy floors or some combination of socks. even those phenomena.

No one really knows what NDE is, or how and why it might happen, although there have been mixed opinions about this issue. Those who believe in supernatural forces think that in this state, the soul of a seriously ill or injured person will leave the mundane body and make the journey to the entrance of the afterlife. Once you reach this place, maybe for some reason, that person is sent back to continue the earthly life, sometimes to help him find the true purpose of life.

But doctors and neurologists do not think so. They found some science-based explanations for this "clinical death" state, and suspected that all were hallucinations , somehow caused by the process of leading to brain death. For years, some people have hypothesized that NDE occurs when the brain is deprived of oxygen, or when a chemical tries to bind to nerve cells to try to remedy this situation. Others think that when near death of the brain, a "flood" of Endorphin or discharge in the Hippocampus region (brain region related to memory) will occur, while some others say that it is simply is due to side effects of anesthesia or medication.

However, so far, science has failed to provide a thorough explanation for this clinical death phenomenon. In an unprecedented large study of this phenomenon, published in the journal Lancet in 2001, Dutch doctors interviewed 344 predominantly elderly patients who survived "close-by "with death with the heart stopped beating. Only 18% of them said they had experienced these wonderful virtual images, and the researchers could not find any association with the time when their hearts stopped beating, or the drugs they were given. use.

In 2010, a study published in Clinical Care magazine provided another possible explanation. The researchers looked at blood samples taken from 52 patients as soon as they resurrected when the heart had stopped beating. With 11 patients who experienced NDE, CO ₂ levels tended to be significantly higher than the remaining cases. This data coincides with other studies on the relationship between elevated CO ₂ levels and visual hallucinations . In fact, climbers often experience the phenomenon of lack of oxygen and must breathe CO _{2 that} also saw light and some other hallucinations similar to "clinical death" or a kind of illusion "cool paradise" that people often see when thirsty and thirsty and tired in the hot desert.

In addition, there is some evidence that NDEs may depend on people's religious beliefs , not just physiological processes. Research shows that young, female and deeply religious patients are more likely to experience NDE than those who fear death.
