Auto-Erotic Asphyxia (AEA) is the term used to describe the practice of cutting off the blood supply to the brain through self-applied suffocation methods while masturbating to orgasm. The interference of blood supply to the brain brought on by AEA can induce cerebral anoxia, a deficiency of oxygen in the brain. It is thought that the lack of blood flow and oxygen can intensify sensations, producing sensations of giddiness, lightheadedness, or exhilaration that can heighten the orgasmic experience.
