Is there any life after death?

 

In this article, we will talk about life after death. Is life after death possible or not? As we belong to different religions, we have different concepts about this question. Like, Muslims, Jewish, Christians have a similar concept about after-life. They thought after death they would be resurrected and entered in Hell and Heaven according to their bad and good deeds respectively on the Day of Judgment. In Hinduism and Buddhism, there is a similar concept about the afterlife. They thought they will be reborn immediately after death and their deeds will determine in what form they will be reborn. But in this article, we will discuss what is the concept of science about the afterlife.

Throughout time and across cultures, people have been conditioned to view death as an end to the experience of life. However, advances in the science of resuscitation and critical care medicine have challenged these assumptions about the end of death. Sam Parnia, director of the Division of Critical Care and Critical Care Research in Lung Disease, Critical Care, and Sleep Medicine at New York University Langone Medical Center, recently spoke with the Academy of Sciences. Dr. Parnia's work sheds light on the fact that death is not an absolute but a process, and what happens when patients experience death - sharing insights from research in his own words:

What is death?

 When the heart stops beating, it leads to death. We call it cardiopulmonary death, which is the definition of death for more than 95% of people. People stop breathing, the brain fails, and all-important processes stop. Recently, with the advent of modern intensive care medicine and the ability to artificially beat people's hearts, doctors like me have been able to beat patients' hearts longer. If a person suffers an irreversible brain injury and causes brain death and causes brain death, but the person's heart is still beating, is it legally declared dead and recovered based on irreversible brain death criteria? , Will die according to brain death criteria. This happens only to part of the time when people are declared dead.

For thousands of years, death was considered an irreversible event and life could not be restored. Over the last decade, we have noticed that the cells of the body, including the brain, begin their death process only after a person dies. I used to think that it would take 5 to 10 minutes for brain cells to die from lack of oxygen, but now it turns out to be wrong. After death, it takes hours, if not days, before irreversible damage to the brain and other organs in the body. It is actually the restoration of oxygen and blood flow to the organs after the human heart has stopped, but then revives and paradoxically accelerates cell death. Therefore, we now need to fight this accelerated secondary injury process in medicine.

Why is the word "near-death experience" inaccurate? 

The problem with this term is that it doesn't match what people actually experience. It is undefined and inaccurate. What does that mean when you say "the plane was caught in a near miss"? Was there another plane that was an inch away from another plane, or was it a mile away? The term is not well defined and does not take into account the fact that many humans have died biologically and returned.

“If they caused pain, they experience the same pain that other person felt, even if they didn't realize it at the time. They actually judge themselves. They suddenly realize why their actions were good or bad, and many claims to see the downstream consequences of their actions.”— Sam Parnia MD, PhD

What is a death experience?

That's why we call it the "death experience." Humans report unique cognitive experiences associated with death. You may feel like you are watching a body and doctors and nurses trying to revive him, but while watching it feels very peaceful. Some report the perception that they may have actually died. They then develop the perception and sensation of being drawn to certain goals. During the experience, they review life from birth to death, and interestingly, the reviews are based on their humanity.

They don't live on what people want, such as careers, promotions, great vacations, and so on. Their point of view focuses on humanity. They become aware of an incident when they lack dignity, act inappropriately towards others, or, conversely, act humanely and kindly.

They relive those moments many times, but what is striking because I can’t explain it is that it expresses the experience from the other person's point of view.

 If they cause pain, they will experience the same pain that others have felt, even if they are unaware at the time. They actually judge themselves, suddenly understand why their behavior is good or bad, and claim that many are looking at the downstream consequences of their behavior.

How does the study of cardiac arrest influence the debate about the nature of consciousness? 

Traditionally, researchers have suggested that the mind and consciousness, that is, ourselves, come from organized brain activity. But no one has been able to show how protein-producing brain cells can produce such different things: thoughts and consciousness. Interestingly, no plausible biological mechanism has been proposed to explain this. Recently, some researchers have begun to question that your mind, your consciousness, your spirit, and what makes you may not be made by the brain. The brain can behave like a mediator. It's not a whole new idea.

They argued that there was no evidence of how brain cells, or connections between brain cells, could generate your thoughts, mind, or consciousness.  There is a fact that humans appear to be fully conscious and involve clear, well-structured thinking processes, and memory formation from the time when the brain was very dysfunctional or even non-functional is mysterious and paradoxical. It is a target. This agrees to increase the likelihood that the entity we call the mind or consciousness will not be produced by the brain. It is certainly possible that there is another level of reality that we have not yet discovered that essentially goes beyond what we know about the brain and dominates our reality. Therefore, I believe that consciousness is a scientific entity that has not yet been discovered and may not necessarily be produced by synaptic activity in the brain.
