Choking

Choking
Health risk	Extremely high (death, brain damage, cardiac arrest)
Legal risk	High (may constitute assault or manslaughter even with consent; specific anti‑strangulation laws in many jurisdictions)
Type	Breath play, carotid compression, edgeplay

In the context of BDSM and Risk-Aware Consensual Kink (RACK), choking encompasses two distinct but sometimes overlapping practices:

• Breath play (airway obstruction): restriction of airflow to the lungs, typically by covering the mouth and nose, pressing on the throat, or using a bag or mask.
• Carotid compression (“blood choke” or “sleeper hold”): pressure applied to the sides of the neck to restrict blood flow to the brain via the carotid arteries and/or jugular veins.

These practices are classified as edgeplay activities at the extreme boundary of risk because even a brief error in technique or duration can cause death or permanent neurological injury. They are never “safe,” only risk‑aware.

Background

Choking has been documented in erotic contexts for centuries, appearing in historical texts and art. In modern BDSM, it is valued for the intense psychological and physiological sensations it produces. However, the medical understanding of its risks particularly the potential for delayed asphyxial death, cardiac arrest, and brain hypoxia has led many risk‑aware communities to treat it with extreme caution.

Appeal

• Psychological domination: The sensation of life‑or‑death control, for both top and bottom, can deepen trust and power exchange.
• Physiological euphoria: Carotid compression can produce a brief, intense lightheadedness or “rush” as cerebral blood flow is reduced; airway restriction may heighten panic and adrenaline.
• Enhanced sexual response: Some report stronger orgasms or altered consciousness when combined with other stimulation.

These effects are accompanied by lethal risks, and the line between euphoria and injury is thin and unpredictable.

Methods

Breath play (airway restriction)

• Manual covering of mouth and nose
• Pressing on the trachea (windpipe) with the hand, arm, or object this method carries high risk of crushing the trachea or larynx
• Plastic bags, hoods, or gas masks that limit fresh air intake
• Smothering with pillows or fabric

Carotid compression

• Applying pressure with the fingers, hand, forearm, or a ligature to the sides of the neck, targeting the carotid triangle
• Typically a bilateral hold (both sides) is more dangerous; even unilateral pressure can trigger a vasovagal response in susceptible individuals
• Often performed with the receiver seated or lying down to prevent falling

Combining methods

Some scenes combine breath restriction and carotid compression, multiplying the risks. Any method that compromises the airway or blood supply to the brain should be treated as a potentially lethal act.

Risks

Immediate physiological dangers

• Cerebral hypoxia: Reduction of oxygen supply to the brain. Loss of consciousness can occur within seconds; irreversible brain damage begins in as little as 3–5 minutes of complete oxygen deprivation.
• Cardiac arrhythmia and arrest: Carotid sinus compression can cause bradycardia, asystole, or ventricular fibrillation. This reflex can occur even with light pressure, especially in individuals with carotid sinus hypersensitivity.
• Tracheal and laryngeal injury: Direct pressure on the windpipe can fracture the hyoid bone or thyroid cartilage, cause laryngeal edema, or trigger laryngospasm all potentially fatal.
• Stroke: Dissection of the carotid or vertebral arteries from manual pressure can lead to thrombus formation and embolic stroke, sometimes with delayed onset (hours to days after the scene).

Delayed and cumulative risks

• Brain injury from repeated sub‑lethal hypoxia (cognitive deficits, memory loss)
• Psychological trauma (panic attacks, PTSD) from perceived loss of control
• “Delayed death” after apparent recovery: in autoerotic asphyxia cases, individuals have lost consciousness and died after initially reviving, due to rebound vasodilation and cardiac arrhythmias.

Contraindications

Individuals with any of the following should never participate in choking:

• Cardiovascular disease (hypertension, arrhythmia, history of stroke or TIA)
• Carotid sinus hypersensitivity
• Epilepsy
• Pregnancy
• Current use of blood thinners or medications affecting heart rhythm

Consent and legal considerations

Consent

Due to the potentially fatal nature of choking, the standard of informed consent is exceptionally high. All participants must:

• Understand and explicitly acknowledge the specific risks (brain damage, cardiac arrest, death) and accept that no amount of skill can eliminate these risks.
• Agree on a clear, unambiguous safeword or non‑verbal signal (e.g., dropping a held object) that immediately stops all pressure.
• Practice frequent check‑ins; the person being choked cannot speak during airway restriction.
• Acknowledge that in many jurisdictions, a person cannot legally consent to bodily harm that may cause death or serious injury, making the consent potentially void in court.

Legal status

In many countries, choking or strangulation is a criminal offence regardless of consent. For example:

• United Kingdom: Under the Sexual Offences Act 2003, consent is not a defence to causing actual bodily harm or more serious injury for sexual purposes (R v Brown [1993]). Additionally, the Domestic Abuse Act 2021 created a specific offence of non‑fatal strangulation.
• United States: Many states have enacted specific strangulation laws that make it a felony, even if the victim “consented.” Choking in a BDSM context can be prosecuted as aggravated assault or manslaughter.
• Australia, Canada, New Zealand: Similar legislation exists; in some jurisdictions, any restriction of breathing or blood flow can lead to criminal charges, including manslaughter in the event of death.

Individuals considering choking must research the laws in their specific jurisdiction and understand that a signed waiver or verbal consent may not protect them from prosecution.

Risk mitigation

No risk mitigation can make choking safe. The following guidelines can reduce, but not eliminate, the risk of death or injury:

• Training: Both partners should learn anatomy and technique from qualified medical or martial‑arts sources (e.g., judo chokeholds applied safely). Never learn from pornography or informal online forums.
• Positioning: The receiver should be seated or lying down to prevent fall injuries if consciousness is lost. Never stand or kneel in an unstable position.
• Pressure location: Avoid the front of the neck (trachea). If carotid compression is used, apply pressure only to the sides with fingers or a soft surface never with a rigid object or full‑force arm lock.
• Duration: Pressure should never be held for more than a few seconds at a time. Release before the receiver signals or shows signs of imminent unconsciousness (eye fluttering, limpness). Continuous monitoring is essential.
• Never use ligatures or gags: Ropes, belts, collars, or gags that prevent the receiver from removing the pressure or communicating are exponentially more dangerous and have been involved in many fatalities.
• Emergency preparedness: Have a plan to call emergency services. Know CPR and basic life support. If the receiver loses consciousness, release pressure immediately, place them in the recovery position, and call for medical help.
• Solo play (autoerotic asphyxia): This is strongly discouraged due to the extremely high risk of death; numerous case series document fatalities from failed self‑rescue.

Known incidents

Medical case reports

Medical literature contains hundreds of cases of death and permanent brain injury from strangulation during sexual activity (often termed “autoerotic asphyxia” or “sexual asphyxia”). Notable findings include:

• Sauvageau (2014) reviewed over 100 autoerotic deaths and found that accidental death typically resulted from failure of the release mechanism, and that even experienced practitioners were not immune.
• Busardò et al. (2017) documented a case of adult choking game fatality, highlighting that hypoxic brain injury can occur even after revival if arrhythmias develop.
• Multiple case reports describe carotid artery dissection and embolic stroke following consensual neck compression.
