Scientists have finally revealed that there might be life or activity after death as a new research shows. 
Death is a depressingly inevitable consequence of life, but now 
scientists believe they may have found some light at the end of the 
tunnel.
The largest ever medical study into near-death and out-of-body 
experiences has discovered that some awareness may continue even after 
the brain has shut down completely.
It is a controversial subject which has, until recently, been treated with widespread scepticism.
But scientists at the University of Southampton have spent four 
years examining more than 2,000 people who suffered cardiac arrests at 
15 hospitals in the UK, US and Austria.
And they found that nearly 40 per cent of people who survived 
described some kind of ‘awareness’ during the time when they were 
clinically dead before their hearts were restarted.
One man even recalled leaving his body entirely and watching his resuscitation from the corner of the room.
Despite being unconscious and ‘dead’ for three minutes, the 
57-year-old social worker from Southampton, recounted the actions of the
 nursing staff in detail and described the sound of the machines.
“We know the brain can’t function when the heart has stopped beating,”
 said Dr Sam Parnia, a former research fellow at Southampton University,
 now at the State University of New York, who led the study.
“But in this case, conscious awareness appears to have 
continued for up to three minutes into the period when the heart wasn’t 
beating, even though the brain typically shuts down within 20-30 seconds
 after the heart has stopped.
“The man described everything that had happened in the room, 
but importantly, he heard two bleeps from a machine that makes a noise 
at three minute intervals. So we could time how long the experienced 
lasted for.
“He seemed very credible and everything that he said had happened to him had actually happened.”
Of 2,060 cardiac arrest patients studied, 330 survived and of 140 
surveyed, 39 per cent said they had experienced some kind of awareness 
while being resuscitated.
Although many could not recall specific details, some themes 
emerged. One in five said they had felt an unusual sense of peacefulness
 while nearly one third said time had slowed down or speeded up.
Some recalled seeing a bright light; a golden flash or the Sun 
shining. Others recounted feelings of fear or drowning or being dragged 
through deep water. 13 per cent said they had felt separated from their 
bodies and the same number said their sensed had been heightened.
Dr Parnia believes many more people may have experiences when they 
are close to death but drugs or sedatives used in the process of 
rescuitation may stop them remembering.
“Estimates have suggested that millions of people have had 
vivid experiences in relation to death but the scientific evidence has 
been ambiguous at best.
“Many people have assumed that these were hallucinations or illusions but they do seem to corresponded to actual events.
“And a higher proportion of people may have vivid death 
experiences, but do not recall them due to the effects of brain injury 
or sedative drugs on memory circuits.
“These experiences warrant further investigation. “
Dr David Wilde, a research psychologist and Nottingham Trent 
University, is currently compiling data on out-of-body experiences in an
 attempt to discover a pattern which links each episode.
He hopes the latest research will encourage new studies into the controversial topic.
“Most studies look retrospectively, 10 or 20 years ago, but the
 researchers went out looking for examples and used a really large 
sample size, so this gives the work a lot of validity.
“There is some very good evidence here that these experiences are actually happening after people have medically died.
“We just don’t know what is going on. We are still very much in
 the dark about what happens when you die and hopefully this study will 
help shine a scientific lens onto that.”
The study was published in the journal Resuscitation.
Dr Jerry Nolan, Editor-in-Chief at Resuscitation said: “Dr 
Parnia and his colleagues are to be congratulated on the completion of a
 fascinating study that will open the door to more extensive research 
into what happens when we die.”
