When a person hangs on his own weight, he basically hangs on his own broken cervical bone. Because the cervical vertebrae are slightly apart, broken, one of the bones in the cervical spine is torn, it comes apart.
Therefore, spinal fluid begins to travel from the brain down to the body.
However, because the nerves are numb due to lack of contact between the vertebrae and the body's nerves, physical strength fails completely.
In living consciousness without the ability to move, therefore, you hang on to your broken bone without being able to move.
DEATH usually occurs within 8 to 10 minutes due to brain death. Fluid from the brain passes down the spinal cord into the body, the brain has no food, no oxygen, no blood, cerebrospinal fluid flows down.
If the knot is tied correctly, the rope around the neck is strongly tightened when falling, which immediately prevents breathing: from this moment also choking occurs, resulting in fainting within 2 minutes (while above takes place simultaneously). And after falling unconscious, there is death due to suffocation + death due to drainage of cerebrospinal fluid down the spine. Both can be the cause.
The worst consequence of suicide or attempted suicide by hanging is a permanent disability when a person is rescued in the first few minutes after hanging - how many minutes exactly, don't know. At that time, the cerebrospinal fluid had not yet begun to pass down the spinal cord, but the cervical spine was severely damaged and the nerves affected, so the person is disabled, condemning it to a life of plant or tetraplegic.

Found this on another forum. Seems like hell to go in my opinion.
