Doctors record 3 minutes of life after ‘death’

London: Life after death? Awareness may continue even after the brain has shut down completely, according to the largest ever medical study into near-death and out-of-body experiences. Scientists at the University of Southampton spent four years examining more than 2,000 people who suffered cardiac arrests at 15 hospitals in the UK, the US and Austria.

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, researchers said. 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, The Telegraph reported.

“We know the brain can’t function when the heart has stopped beat ing,” said Dr Sam Parnia, at the State University of New York.

“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,” Parnia said.

Of 2,060 cardiac arrest patients, 330 survived and 140 said they had experienced some kind of awareness while being resuscitated. One in five said they had felt an unusual sense of peacefulness while nearly one third said time had slowed down or speeded up.
