Science Is Starting to Explore the Gray Zone Between Life and Death

We used to think of death as a moment. We reel when a beloved person meets a tragic end, be it in real life or our favorite show. The reality is, death is often a long, drawn out process that has to do with treatment, hospitals, and in the end, hospice care. Of course, it can strike suddenly too and without warning. But medical science has progressed to the point where we aren’t thinking of death so much as a moment anymore, but a process.

So does that mean we can slow it down or even pause it? According to Dr. Sam Parnia, in his book Erasing Death, new techniques are being used which can reinvigorate the body and the brain. He also believes that death could someday be reversible.

Dr. Parnia has done studies on sustained resuscitation. He says some patients can be brought back merely with CPR, hours after their heart stopped beating, without any permanent damage to the brain. He’s also studied near-death and out-of-body experiences to see if these hold any medical secrets, which could be used to tell us something about the condition. Could a near death experience signify resuscitation of the brain, Dr. Parnia wonders? 

“We’ve never had an objective method to go beyond the threshold of death and study what happens both biologically and from a mental and cognitive perspective,” he told NPR’s Terry Gross on Fresh Air. “Therefore everything that we deal with is basically hearsay and people’s own beliefs.”

In his experiments, he found that cooling the body a few degrees Celsius can actually slow the rate of cell death, particularly of neurons in the brain. He isn’t alone. In fact, a number of different medical professionals are leaning toward longevity medicine.
