Erotic asphyxiation is also referred to as breath control play, hypoxyphilia, or asphyxiophilia. This is the calculated oxygen restriction which is usually achieved via choking to achieve sexual arousal. Other methods include chest compression, placing a plastic over the head, using solvents, or a combination of these. Individuals who engage in this activity are also called “gaspers”. When the gasper’s brain is deprived of oxygen, she or he may enter a semi-hallucinogenic state which increases feelings of giddiness and pleasure when combined with orgasm. Since this is a highly risky practice, this may lead to accidental death or brain damage if incorrectly performed.
