WHAT EXACTLY DEATH MEANS?

There are many facts proved by practically experimenting, but still, there is a mystery where the truth behind it can never be experimented on, and it is death. When we are about to die, in-depth, when our heart stops beating, our mind will be consciously working for the next seven minutes even after the heartbeat stops. A near-death experience(NDE) is a deep-seated personal experience correlated with death or looming death that the concerned person claims share similar characteristics. In extreme medical cases, such NDEs may happen. At that condition, it has described that the person might feel like the soul has trapped inside his body, that no way he could move. Medicos explain that before death when a human sense like he is inside a deep dark cave with a little bright spot at the end, then it is due to the lack of blood supply to the eye, and insufficient oxygen. One more theory about the last stage before our death is, we will perceive the flash of our whole life for the last seven minutes of our death. Doctors examined that the moment after death, a large amount of melatonin and dopamine have secreted from a few bodies. Melatonin is a hormone that regulates the sleep-wake cycle, and dopamine is the hormone that stimulates happiness.

Doctors in a Canadian intensive care unit stumbled on strange cases last year when life support has turned off for four terminal patients, one among the four showed persistent brain activity even after they were declared clinically dead. Theories say that when the brain recognizes our body cannot support henceforth, then the brain will address the signal to the heart, reacting to that signal, the heart stops the beating. Though the heart stops beating at the moment of death, the brain will not cease to transmit the electrical signals, which is termed clinical death. After 7 to 8 minutes of the clinical death, the brain ends its activity and is termed biological death. Even after death, the muscles in our body continue to either expand or contract, which means the muscle activity does not stop and create different kinds of sound. The actual moments of death is tricky to decode.

SIGNS OF DEATH CONFIRMATION

We all came across movies where the doctors flash a spotlight in a patient’s eye to check the brain-death, why is it for?

The answer is simple, at the time when the activity of our brain ceases, it cannot recognize the spotlight. As a result, the pupil does not shrink.

In mammals the brain controls the pupil, when a light is projected, our pupil must shrink by receiving the signal from the brain.

The study of the people from near-death experiences shows that few people have negative experiences in the moments leading up to death, and most have, in fact, felt an “overwhelming feeling of peacefulness.
