Non-fatal strangulation (NFS) is never just another assault. It is a deliberate tactic of control and stands as one of the most reliable indicators that intimate partner violence has reached a potentially lethal stage. Yet, too often, it is dismissed or minimized when there are no visible injuries. Survivors are told, “It couldn’t have been that bad.” The reality is that it always is that bad. The absence of marks does not mean the absence of danger.
This is the lived reality for many victim-survivors. Having your breath taken away by someone you know is an experience of terror that words cannot fully capture. For most, it is the moment they realize the person they trusted is fully capable of ending their life in an instant. When I speak with women who have survived non-fatal strangulation, they rarely hesitate in describing it: “I thought I was going to die.”
My recent LinkedIn article on non-fatal strangulation has received strong international engagement and a highly positive response from readers and professionals across multiple sectors. I warmly invite you to explore that article as well.
My peer-reviewed article on non-fatal strangulation has also recently been published in Partner Abuse. For those working in safeguarding, risk assessment, or frontline response, the following reference may be of interest:

What Happens to the Body During Strangulation
To truly understand the seriousness of strangulation, we must look at the medical facts. These are not exaggerated numbers; they are established physiological realities (see Physiological Consequences of Strangulation):
- Unconsciousness can occur in seconds.
- Anoxic seizure, bladder incontinence, and even bowel incontinence can follow.
- Just 11 pounds of pressure on the neck is enough to block blood flow.
- In 30 seconds, temporary or permanent brain damage may begin.
- Death can occur between 62 and 152 seconds.
From “Play” to a Lethal Rehearsal
The following example shows how what is first rationalized as “sexual play” can quickly become a rehearsal for lethal violence. Each incident becomes more violent, more controlling, and more dangerous. This is the pattern of escalation in action. Both professionals and survivors must recognize strangulation for what it truly signals: a shift toward life-threatening harm.
- January: a brief act of manual strangulation during sex. It was described as consensual. There was no loss of consciousness and no threats.
- April: the same act, but prolonged. This time, the survivor lost consciousness.
- June: not in the bedroom but in an argument. He used his forearm to pin her against the wall. She lost bladder control. The time between incidents was shortening.
- July: a sexual assault involving strangulation. This time he added an explicit threat: “Next time you won’t wake up.” And if she disclosed? Her children or pets would pay the price.
Real Cases of Non-Fatal Strangulation
In Northern Ireland, where non-fatal strangulation became a standalone offense in 2023, police recorded an estimated 1,893 reports of NFS from June 2023 to May 2025, leading to 1,755 arrests. Detective Superintendent Lindsay Fisher noted that 10–12% of domestic abuse victims report having been strangled, flagging its prevalence and lethal potential.
In England & Wales, Sky News reported that about 70% of non-fatal strangulation cases were dropped over evidential issues, despite more police recording under the standalone offense law.
In September 2025, a man was sentenced to 20 years after being convicted of attempted murder and intentional strangulation of his partner in Greater Manchester.
These cases demonstrate why simply ticking a box for “has strangulation occurred?” is not enough. Static checklists can obscure the reality of how abuse escalates, slips past detection, and ultimately leads to life-threatening violence. We must look beyond isolated incidents to see the full pattern of risk.
The Evidence
It is important to recognize that strangulation is a significant predictor of future lethal violence. If your partner has strangled you, it is crucial to acknowledge the seriousness of this behavior.
Research published in the Journal of Emergency Medicine indicates that prior non-fatal strangulation by an intimate partner increases the risk of attempted homicide by approximately sevenfold and completed homicide by about eightfold.
Dr. Jacquelyn Campbell, Professor of Nursing at Johns Hopkins University, has emphasized this repeatedly:
“Non-fatal strangulation is an important risk factor for homicide of women. Prior non-fatal strangulation was associated with greater than six-fold odds of becoming an attempted homicide and over seven-fold odds of becoming a completed homicide.”
Dr. Clare Healy, a forensic specialist often described as New Zealand’s foremost GP expert on medical care after sexual assault, supported this by stating:
“Non-fatal strangulation is a significant predictor of future lethal violence.”
The evidence leaves no room for doubt. Strangulation is among the clearest warning signs that a relationship is moving toward lethal violence.
Why This Matters
For survivors, strangulation is not just a terrifying physical assault; it is a calculated act of psychological domination. The message is clear and chilling: “I control your life, and I can end it at any moment.”
This is why strangulation is such a powerful weapon of control. It silences, coerces, and instills fear in ways that words never could. After experiencing strangulation, many survivors comply with every demand, not out of choice, but because they know that resistance could cost them their lives.
For frontline professionals, recognizing this dynamic is critical. When a survivor discloses strangulation, she is not overreacting. She is alerting you to a level of risk that demands immediate and serious intervention.
A Call to Action
Non-fatal strangulation is one of the most urgent warning signs we have. It cannot be reduced to a checkbox or dismissed as a minor assault, even when there are no visible injuries. It is, in effect, a rehearsal for homicide.
We must shift our focus from isolated incidents to the broader pattern of abuse. Frontline responders need to be trained to ask the right questions and to recognize the significance of strangulation disclosures. These warnings must always be treated with the urgency they demand.
Survivors deserve to be believed and protected. As a society, we have a responsibility to act before tragedy strikes, not after. When the warning signs are clear, we cannot afford to look away.
