Also known as breath play · sexual choking · erotic asphyxiation
An adult interest in fantasies or acts involving restricted breathing or blood flow. Community language often says sexual choking, while clinical and legal sources distinguish external neck compression as strangulation from choking on an internal obstruction. Every form of actual oxygen or blood-flow restriction can cause severe injury or death.

In brief
Fantasy can be represented; oxygen and blood-flow restriction cannot be made reliably safe.
Breath restriction interest can refer to fantasy, symbolism or physical acts, but those categories are not medically equivalent. Fiction about surrender or danger can be represented without touching the neck, covering the airway, compressing the chest or reducing oxygen. Actual strangulation or suffocation is a high-risk event: consent, trust, strength, experience or a commercial product cannot create a reliable safe threshold. This entry explains terminology, evidence, warning signs and law; it deliberately provides no method, pressure, timing, body-position or equipment guidance.
What research can—and cannot—show
Conte and colleagues' 2025 study examined how Australian adults aged 18–35 understood and negotiated sexual choking or strangulation, while Sharman and colleagues surveyed 4,702 Australian adults in the same age range. US adult studies have examined prevalence, self-reported symptoms, brain imaging and biomarkers. Together they document that the behaviour occurs and that some participants misunderstand or minimise its risks; they do not establish a harmless form.
The evidence is still concentrated in particular countries and younger-adult samples. Several neurological studies are small, cross-sectional or pilot investigations, so associations cannot prove the direction, permanence or size of every effect. Sweeney and colleagues' 2026 randomized crossover study reported acute differences after strangulation-involved encounters, but a small study cannot define a safe pressure or duration. Uncertainty about long-term outcomes is not evidence of safety.
EDITORIAL ILLUSTRATIONEvidence does not establish a safe method
Direct evidence is limited and severe outcomes can occur without a reliable threshold. Popularity, consent or familiarity cannot turn breath restriction into a predictably safe practice.

Breath restriction interest
The broad adult-interest label, which may include fantasy, imagery or actual restriction. The label alone does not reveal what a person wants or has agreed to.
Strangulation
External pressure or compression around the neck. Medical and legal sources use this term even when a community calls the act choking and even when no mark is visible.
Choking
Clinically, an internal blockage of the airway. In sexual conversation the word is often used for strangulation, so relying on it without clarification can obscure the actual risk.
Fantasy or symbolic representation
Fiction, audio, dialogue, abstract imagery or role-play with no pressure on the neck, chest or airway and no reduction of breathing or blood flow.
Physiology, terminology and invisible injury
External neck pressure can affect blood vessels, the airway, nerves and structures of the throat. Gloucestershire Hospitals NHS guidance notes that a person can feel well and show no external mark while internal swelling, vascular injury or neurological symptoms develop later. Loss of consciousness is a medical emergency, not a predictable endpoint or evidence of control.
The phrase breath play can misleadingly suggest that airflow is the only concern. Strangulation may interfere with blood flow to and from the brain as well as breathing, and a person cannot reliably assess internal injury by appearance. Oxygen saturation readings, pain tolerance, prior experience, physical strength or the absence of bruising do not certify that no harm occurred.
Symbols, media and accessible alternatives
A broken-ring safety symbol, an abstract breath waveform, an open doorway, a red stop card or clearly labelled fiction can communicate danger, pause and surrender themes without displaying a body or an equipment arrangement. Scarves, collars, masks, bags, straps and medical devices should not be presented as breath-restriction tools; ordinary or commercial objects do not remove physiological risk.
Adults interested in the psychological theme can use text, audio, dialogue, lighting, facial expression or other representation that leaves the neck, chest, airway and breathing unaffected. Captions, transcripts, adjustable audio, high-contrast safety cues and non-verbal communication options improve access. No one should have to tolerate oxygen restriction because disability, speech difference or sensory needs make a conventional stop signal harder to use.
EDITORIAL ILLUSTRATIONSymbolism can avoid physical restriction
Lighting, sound, language, framing and freely moving fabric can represent pressure or release without contact with the neck, chest, airway or breathing equipment.

Consent, medical help, law and clinical distinction
Consent to one sexual activity does not imply consent to neck pressure or impaired breathing, and an unconscious person cannot communicate or consent. Dunkley and Brotto's review identifies prior negotiation and continuing communication as recurring BDSM consent practices, but consent does not make strangulation medically safe. In England and Wales, strangulation and suffocation have been specific offences since 7 June 2022; CPS guidance explains a limited consent defence and that it does not apply where serious harm occurs with intention or recklessness. Other UK jurisdictions have their own law.
After any neck pressure, NHS advice is to seek medical assessment even without immediate symptoms. Call 999 for loss of consciousness, confusion, breathing or swallowing difficulty, voice change, weakness, numbness or other serious symptoms; NHS 111 can advise on less urgent concerns. Non-consensual strangulation, intimidation and coercive control are violence, not kink. An interest or fantasy is not itself a paraphilic disorder: WHO clinical guidance instead focuses on marked distress, significant impairment, serious risk or non-consent.
EDITORIAL ILLUSTRATIONSymptoms need ordinary medical attention
Confusion, breathing difficulty, collapse, voice change, weakness or other concerning symptoms require prompt medical help. A scene label must not delay emergency action or honest clinical information.

Non-graphic examples
What the umbrella may include
An adult reading fictional danger-and-surrender imagery while choosing no physical restriction.
Partners using dialogue, lighting and an abstract breath soundtrack while leaving breathing and blood flow unaffected.
An educator distinguishing medical choking from external neck compression so learners understand that sexual 'choking' usually means strangulation.
An adult declining neck contact despite having consented to other kinds of intimacy or power exchange.
Seeking urgent medical help after neck pressure when a person has voice change, confusion, difficulty breathing or swallowing, weakness or loss of consciousness.
