Execution by Hanging

Hanging is the suspension of a person by a noose or ligature around the neck. The Oxford English Dictionary states that hanging in this sense is "specifically to put to death by suspension by the neck", though it formerly also referred to crucifixion and death by impalement in which the body would remain "hanging". Hanging has been a common method of capital punishment since medieval times, and is the official execution method in numerous countries and regions. The first account of execution by hanging was in Homer's Odyssey. In this specialised meaning of the common word hang, the past and past participle is hanged instead of hung.

Hanging is also a common method of suicide in which a person applies a ligature to the neck and brings about unconsciousness and then death by suspension. Partial suspension or partial weight-bearing on the ligature is sometimes used, particularly in prisons, mental hospitals or other institutions, where full suspension support is difficult to devise, because high ligature points (e.g., hooks or pipes) have been removed.

There are four ways of performing a judicial hanging: suspension hanging, the short drop, the standard drop, and the long drop. A mechanised form of hanging, the upright jerker, was also experimented with in the 18th century, with a variant of it used today in Iran.

Suspension, like the short drop, causes death by using the weight of the body to tighten around the trachea and neck structure with the noose. Prisoners are reported to have little or no struggle before they go limp because their jugular vein and carotid arteries are blocked and blood flow to the brain is reduced. The person slowly dies of strangulation, which typically takes between ten and twenty minutes, resulting in a considerably more elongated and painful death as compared to the standard or long drop hanging. "If the airway is constricted, and full suspension achieved (feet fully off the floor), this method, at least initially, is likely to be very painful, as the person struggles for air against the compression of the noose and against the weight of their own body, being supported entirely by the neck and jaw."
