We have all thought about what happens after
we die. Do we go to a place in the sky and are welcomed
by family and friends? Do we get reincarnated as a beautiful butterfly? Is there nothing at all? At this point in time, no one can definitively
say what happens to your consciousness or spirit after you die. However, doctors such as Sam Parnia at NYU
Langone Health have discovered evidence that after the body dies, your consciousness may
continue on. Is this proof there is an afterlife? Can science provide evidence for the existence
of consciousness after the body shuts down? Let's find out. Someone is considered clinically dead when
their heart stops beating. It is called death by cardiopulmonary criteria. Death occurs in this way because the heart
stops pumping oxygen rich blood and nutrients around the body, which causes all the organs
and tissues to shut down. Advances in medical practices such as CPR
and defibrillators have made death reversible in a sense. It is believed right now that after the heart
stops, you still have five to ten minutes before you brain cells die and brain damage
becomes irreversible. However, recent research suggests that five
to ten minutes worth of brain activity after the heart stops beating is incorrect. Instead, a person may have hours, or even
days, of brain activity after their heart stops. If this is true, then what is happening in
your brain when you are clinically declared dead? What is your consciousness doing? This paradox is what medical researchers are
trying to figure out. What is consciousness? Where does it lie within the body? Your consciousness makes you, you. It is undeniably a product of the brain, but
we are not entirely sure where your consciousness is manifested and kept within the nervous
system. Is it in the muscle tissue? The synapsis? Or is it the energy flowing between nerves
that gives us consciousness? Because of countless research studies, we
know that when we have a thought parts of our brain send chemical and electrical signals
through the nerve cells. Since thoughts and consciousness are closely
related, our essence may be contained within the cells and chemicals of the brain. This means your sense of self, and what makes
you you, could just be bundles of proteins and organic compounds. You may ask, “when the brain shuts down
and the cells start to die does our consciousness go with it?” That’s the question Dr. Sam Parina and others
are trying to figure out. Can one brain cell hold your consciousness
or do you need millions of brain cells to create who you are? Parina states that there
is no reason to believe that millions of cells are necessary for your consciousness to exist. It's difficult to quantify, but your consciousness
may be contained in every one of your trillions of cells. Just think, every time you lose a brain cell
you may be losing a part of yourself. Spooky right? If your brain hurts from thinking about what
gives you consciousness, stay with me for just a while longer. Regardless of which part of the brain gives
you emotions, personality, and your essence, none of that matters when all of your cells
die. So what happens to you after the heart stops
beating and your consciousness moves on? Is there an afterlife? Studies have shown that after someone is clinically
dead their consciousness remains in or around the body for a period of time. Since death is not an off switch, but more
of a slider, you aren’t alive one second and dead the next. When the heart stops, everything else in the
body keeps going, then slowly starts to die over time. This means that for a significant time after
death, death can be fully reversible. Technically, there are loads of people walking
around in their afterlife today. People who have had heart attacks or gone
into cardiac arrest have had their heart stop. They were dead. Doctors then brought them back to life. Therefore, they are living post death, or
after life. But let's focus on what happens when your
heart shuts down for good, when there is no bringing you back. What happens to your consciousness then? If you are dead you should have no recollection
of the time your heart stopped and when it restarted. However, this is not the case. There have been many scientific reports that
show people have lucid memories and experiences even while their heart is not beating. Accounts of patients seeing bright lights
while they are clinically dead is common. Even though the brain is not receiving oxygen,
it would seem that there are still experiences and memories being formed. The process of making observations, and then
being able to recall those observations, is part of what makes you you. Why do so many people who are dead see a bright
light? Maybe it is an experience that gives a glimpse
into life after death. People who can recall experiences after their
heart stops beating are recalling events from the afterlife. It is entirely possible that the light people
see after they die could be the first step towards moving into the afterlife. Other accounts have recorded people hearing
full conversations after they were pronounced dead. When their heart is restarted and they regain
the ability to talk, these people recount what the doctors and nurses were talking about
while trying to bring them back to life. If the brain and your consciousness stop at
the time of death this would not be possible. Perhaps this is happening because the mind
is gathering information to prepare your consciousness for the afterlife. There is evidence to suggest that a burst
of energy flows through the brain after someone dies. This may be your consciousness transitioning
to the afterlife. The brain may be carrying out a yet unknown
process that allows your consciousness to prepare for whatever comes next. After this burst of energy, your brain cells
take days to reach a point where they are no longer carrying out basic functions. To be clear, this does not mean the person
is not dead, they are, but their consciousness may be transitioning to the after life. Another commonality between people who have
had post death experiences is that they often see a guiding figure. The figure varies between people and accounts,
but it seems that there is someone or something to guide you after death. Is this figure just a way your mind copes
with being dead, or is there more to it? It has been suggested that these guiding figures
might just be hallucinations. It’s interesting to note that hallucinations
are individualistic, so it is odd that multiple people are having similar apparitions taking
them into the afterlife. The only reason we know of these mysterious
figures is because people who have been brought back to life through CPR or shocking the heart
have told us. Perhaps the guiding figure is a manifestation
of the medical professionals that are bringing these people back to life. Or maybe they are something in the afterlife
that helps us transition from being alive to being dead. Some of the most interesting and unexplainable
afterlife experiences are accounts of people who claim they had left their dead body and
watched themselves be operated on from above. It would be easy to chalk these stories up
as hallucinations or that they are made up. The problem is the patients can recount vivid
details from their out of body experience. On more than one occasion patients who have
died can recall events that occured after their heart stopped. They could explain what the doctors were doing
and objects in the room. When medical professionals were asked if the
memories the patients recalled were accurate, they confirmed that they were. How could someone who was clinically dead
have seen and observed so many details? We just don’t know. Perhaps it has something to do with what our
consciousness is made of. Maybe after we die our consciousness leaves
our body in a form of energy yet to be discovered. This seems unbelievable, but it does serve
as a preliminary hypothesis as to how people could have out of body experiences. As of yet there are no real good explanations
for how people are able to make accurate observations from outside of their bodies, especially when
they are considered clinically dead. You might wonder if these experiences are
happening only in certain parts of the world or in certain age groups? It would seem not. Post death experiences tend to be pretty universal
across age groups and location. Data gathered from every content and every
age group have similarities when comparing afterlife experiences. When Dr. Parina interviewed a three year old
boy who survived a cardiac arrest from an epileptic seizure he said "When I died I saw
a bright lamp." This aligns to the stories of adults seeing
a bright light when confronted by death. The child also recounted that "grandma came
to meet me and said I was going to be okay." This is reminiscent to the guiding figure
that many people see during their after life experience. Other children have described their experience
after death as seeing a "being of light." Maybe this is a marriage between the bright
light and guiding figure. There are no accounts of them describing the
light as God, Jesus, or Santa Clause, because as children, these concepts are not associated
with death. Yet younger children report after life experiences
similar to older children and adults. It is important to note that these experiences
are not the same as sleep paralysis or “locked-in” syndrome, where people are conscious and awake,
but unable to speak or move. Researchers have ruled this out due to the
fact that the patient's heart has completely stopped beating. During paralysis the heart slows to a meditative
state, but never stops. The accounts from patients who have seen themselves
on the operating table consistently state they were in no pain, and oftentimes they
were confused why everyone was worried about them. It is almost as if when you die your mind
and consciousness relaxes, and all of the pain your body feels is cut off from your
mind. Maybe this shows that your consciousness is
not a part of the body at all, but just contained within it waiting to be set free. It is uncanny events like these that make
Dr. Sam Parnia hypothesize that the psyche or “self” may not originate in the brain
at all, but could possibly be a separate undiscovered entity. Parnia believes that consciousness could be
something similar in nature to electromagnetic radiation, like radio waves and visible light. There is no definitive evidence for what makes
up consciousness or your psyche. But if it was something similar to energy
waves, that would help explain observations that occur from outside the body because energy
is not confined to a corporeal form. Then again, if that’s the case why can’t
we just shoot our conscious selves out of our brain any time we want? Not all after life experiences are equal or
pleasent. During a study one man recounted that when
his heart stopped beating, and the doctors were trying to bring him back to life, he
experienced the guiding figure. Except in this case it was an unfamiliar woman. She was floating and beckoning him to join
her from the ceiling in the corner of the room. Kind of creepy when you think about it. The man remembers thinking, “I can’t get
up there.” Then as he finished the thought he suddenly
was “up there, looking down” at himself. He saw his blood pressure being taken and
a breathing tube put into his mouth. The nurse was giving him CPR. He could accurately describe the people, sounds,
and events leading up to his resuscitation. Other people have recounted being sucked into
a deep black void. Almost like a star being sucked into a blackhole
and torn apart. Clearly not the most reassuring after life
experience. But it could be worse. There are others who have seen grotesque creatures
that wail and moan in pain. They beckon the person towards them. Luckily those people were brought back to
life before they were forced to follow the creatures. But it begs the question… what happens to the people who experience
these visions and don’t get pulled out of it by doctors restarting their heart? Dr. Parnia is not a religious man and insists
that his experiments are not to prove there is a supernatural afterlife. Instead, he aims to understand what happens
to the consciousness after the body dies to avoid “disorders of the consciousness.” This includes patients who are left in a permanent
vegitative state after their brain is starved too long for oxygen. Parnia wants to prevent cases like this, while
also testing the accuracy of after life experiences using a scientific approach. Research shows that people who have these
after death experiences are often transformed by the experience itself. They change their lifestyle to help others
and become less self-centered. Parina says patients who have died and have
been brought back to life “view the world in a different way.” People who have an after life experience tend
to have a shift in perspective that focuses on their humanity. Parnia also reports that following an after
life experience people become more empathetic and reflective on things they’ve done. Especially if their actions have hurt others. They often describe the experience from the
other person’s perspective, which causes emotional distress to themselves. Is this our consciousness reaching out to
another consciousness? Do people who have experienced death literally
have a more connected world view? Whether you believe in the afterlife or not,
scientists are finding more and more evidence that consciousness remains even after the
body dies. Experiences that people have had while clinically
dead are hard to explain at this moment in time. It would seem that the frequency of shared
after life experiences across the world and age groups would indicate something happens
to you after you are clinically dead. We don’t know what is in store for us after
this life, but we do know that death of the body is not the end for our consciousness,
maybe not even by a long shot. If talking about death doesn’t freak you
