<\/p>\nHere’s what the new studies have revealed<\/h2>\n<\/p>\n
<\/p>\n
Researchers say people may remain conscious for several hours after heart and brain stop, and that we must redefine death.<\/p>\n<\/div>\n
<\/p>\n
According to a study, people may be conscious for several hours after they have died, as evidence has been found that consciousness may persist long after the heart has stopped pumping and the brain has stopped sending electrical impulses.<\/p>\n<\/div>\n
<\/p>\n
That the brain can send signals for a few seconds after death has long been known.<\/p>\n<\/div>\n
<\/p>\n
However, emerging research suggests people are alert to what is happening around them while they are biologically dead.<\/p>\n<\/div>\n
<\/p>\n
Death is not an \u201cinstantaneous event\u201d but instead \u201cunfolds as a process\u201d, and the brain declines over hours instead of stopping abruptly, as per the study presented at the American Association for the Advancement of Science annual conference in Phoenix.<\/p>\n<\/div>\n
<\/p>\n
Researcher Anna Fowler at Arizona State University analysed more than 20 studies on people\u2019s near-death experiences, as well as studies conducted in animals on what happens in the brain after death.<\/p>\n<\/div>\n
<\/p>\n
In some human patients who experienced \u201ccomplete circulatory standstill\u201d, which means the heart stops beating, what happened is that they were later able to recall what was happening around them.<\/p>\n<\/div>\n
<\/p>\n
Ms Fowler writes in her study that \u201cdeath, once believed to be a final and immediate boundary, reveals itself instead as a process \u2013 a shifting landscape where consciousness, biology and meaning persist longer than we once imagined\u201d.<\/p>\n<\/div>\n
<\/p>\n
\u201cConsciousness may not vanish the moment the brain falls silent. Cells may not die the moment the heart stops.\u201d<\/p>\n<\/div>\n
<\/p>\n
\u201cThis research proposes that death is not the sudden extinguishing of life, but the beginning of a transformation, one that medicine, philosophy and ethics must now approach with deeper humility and renewed clarity\u201d, she adds.<\/p>\n<\/div>\n
<\/p>\n
However, Ms Fowler warns that the work has implications for the ethics of organ donation, as around one in three organ donations occur after the heart has stopped.<\/p>\n<\/div>\n
<\/p>\n
As it is ideal to take organs within minutes of the heart ceasing to operate and a person is declared dead, this is done to ensure the organs are fresh and not damaged for their transplantation into a patient in need.<\/p>\n<\/div>\n
<\/p>\n
Ms Fowler says that in these cases a donor may still be conscious while their organs are harvested.<\/p>\n<\/div>\n
<\/p>\n
She said she believes there have been instances of organs being harvested while the donor is still conscious.<\/p>\n<\/div>\n
<\/p>\n
As for what happens when we die, she says that we cannot know for sure.<\/p>\n<\/div>\n
<\/p>\n
\u201cWhat does happen when we die? Nobody really knows,\u201d she added. \u201cI really want people to think and consider what it means to truly die.\u201d<\/p>\n<\/div>\n
<\/p>\n
According to Ms Fowler, the definition of death in the US, which was set out in the 1980s, should be updated to reflect that death is not a singular event.<\/p>\n<\/div>\n
<\/p>\n
\u201cIt should be considered in phases,\u201d she said. \u201cIf you have cancer, you could have stage three cancer, stage two cancer. Well, there are stages of death.\u201d<\/p>\n<\/div>\n
