Question: Whats The Longest Someone Has Died And Come Back To Life?

How long can a person be dead and come back to life?

For this, a general rule of thumb is that brain cells begin to die after approximately 4-6 minutes of no blood-flow.

After around 10 minutes, those cells will cease functioning, and be effectively dead.

That said, there are some exceptions to that rule..

How long does the body stay alive after death?

Muscle cells live on for several hours. Bone and skin cells can stay alive for several days. It takes around 12 hours for a human body to be cool to the touch and 24 hours to cool to the core. Rigor mortis commences after three hours and lasts until 36 hours after death.

Does dying hurt?

Reality: Pain is not an expected part of the dying process. In fact, some people experience no pain whatsoever. If someone’s particular condition does produce any pain, however, it can be managed by prescribed medications. Myth: Not drinking leads to painful dehydration.

What happens immediately after you die?

Can a person die and come back to life?

Science is far from establishing when a body’s capacity for consciousness actually leaves it. “We don’t know how long it takes after death for the cells to decay to such a point that no matter what you do, you can never get them back again,” Parnia says. Which means that humans may take hours to fully die.

Can a person still hear after they die?

Hearing is widely thought to be the last sense to go in the dying process. Now UBC researchers have evidence that some people may still be able to hear while in an unresponsive state at the end of their life.

Can a dead person cry?

After death, there may still be a few shudders or movements of the arms or legs. There could even be an uncontrolled cry because of muscle movement in the voice box. Sometimes there will be a release of urine or stool, but usually only a small amount since so little has probably been eaten in the last days of life.

What happens the moment you die?

As death nears, it’s very common for a person’s breathing to change, sometimes slowing, other times speeding up or becoming noisy and shallow. The changes are triggered by reduction in blood flow, and they’re not painful. Some people will experience a gurgle-like “death rattle”.

Do people know when they die?

Death just became even more scary: scientists say people are aware they’re dead because their consciousness continues to work after the body has stopped showing signs of life. That means that, theoretically, someone may even hear their own death being announced by medics.
