: Hanging is a form of asphyxia, which occurs when the body, or a part of it, is deprived of oxygen. In the context of hanging, asphyxia is caused by the constriction of the neck, which can obstruct the airway and/or the blood vessels, leading to death. Asphyxia can result from various causes, not just hanging, and is a critical area of study in forensic science to determine the cause and manner of death.
