HeckNo Grabs and hands on the neck: what everyone should know
- No marks means nothing — about half have none. Say “strangled” when you go.
- A partner's hands on your throat once is the clearest warning measured.
- There is no safe way to strangle. Nobody can feel the edge.
- No release has ever been tested. That half needs a real partner.
MOSTLY ABOUT THE NECK
Hands on you
Most of this lesson is about pressure on your neck. It is the grab where what you already know changes what happens to you afterwards.
Why the neck is different from everywhere else
In the England and Wales crime survey, 8.1% of rape victims were choked or strangled.
The gap between the two figures is the whole point of this lesson.
In the UK database that links offences by behaviour, strangulation appears in 12% of stranger sexual offences — and in 36% of stranger sexual homicides.
The odds of attempted homicide, and of completed homicide, for a woman whose partner had previously strangled her, compared with women whose partners had not.Glass et al., 2008 — non-fatal strangulation as a risk factor for homicide of women (11 US cities).
Read that one carefully.
It was measured in intimate partner violence, comparing women who had been attacked or killed with abused women who had not been.
It does not transfer to a stranger in a car park.
We are not going to pretend it does. What it means is narrower and more useful than that.
A partner put his hands round your throat once, in an argument, and was sorry afterwards. What is that?
Answer: The strongest warning sign the research has measured
The strongest one measured. An earlier strangulation went with 6.7 times the odds of a later attempted killing and 7.5 times the odds of being killed. It was measured in relationships, not stranger attacks, and it is a marker rather than a cause.

Of strangulation victims have no visible external injury at all.Faculty of Forensic and Legal Medicine — guideline on the assessment of non-fatal strangulation.
Not where anyone could photograph it.
In the study that looked specifically at sexual assault cases, 48% had any external injury. But 86% had symptoms.
Who that study examined, and when.
It examined 204 people at a referral centre, around 70% of them within two days.
Afterwards there is nothing to see on your neck. What does that tell you?
Answer: Nothing at all
Nothing at all. About half of people who are strangled have no visible injury. In the study of sexual assault cases, 48% had any external mark — and 86% had symptoms. The damage happens inside the neck, where nobody can photograph it.
Faculty of Forensic and Legal Medicine — guideline on the assessment of non-fatal strangulation.All three of you can be wrong.
This is why the police, a doctor, or you yourself looking in a mirror can all conclude that nothing much happened, and all be wrong.
Days, weeks, and as late as a year.
Damage to the arteries in the neck can appear days or weeks afterwards, and has been recorded as late as a year.
A scan is the only way to rule it out.
“There were no marks” is not a reason to skip one.
THE WORD YOU USE
The word matters more than it should
Strangulation is pressure on the neck from outside. Choking is something stuck inside the airway, like food. Use “strangled”.
You are in front of a doctor. Which word do you use?
Answer: “He strangled me”
Strangled. Choking is something stuck inside the airway, like food; strangulation is pressure on the neck from outside. Almost everyone says choked, and doctors know that — but the word you use changes what gets examined, what gets written down, and what can be charged.

For a lot of you, this comes up in bed first.
A lot of people your age will meet pressure on the neck in bed long before they ever meet it in an assault.
The physiology is identical either way.
We are not going to teach you that a hand on the throat is an emergency while your own life says it is ordinary.
Of 16 and 17-year-olds in a UK survey who had had sex reported having been strangled during it.Institute for Addressing Strangulation, November 2025 — survey of 4,175 people aged 16–34 in the UK.
29% of 16 to 34-year-olds believe there are safe ways to strangle someone during sex. Among those who have done it, that rises to 43%.Institute for Addressing Strangulation, November 2025 — survey of 4,175 people aged 16–34 in the UK.
Is there a safe way to strangle someone during sex?
Answer: No
No — that is the position of the Home Office funded institute that asked 4,175 people about it. Experience makes people more confident, not more correct. The neck does not work differently because both of you wanted it.
Institute for Addressing Strangulation, November 2025 — survey of 4,175 people aged 16–34 in the UK.Nobody can feel where the limit is.
In the only human experiments ever conducted, loss of consciousness took under seven seconds on average, and varied a great deal between individuals.
In England and Wales, it is its own offence.
In England and Wales, non-fatal strangulation has been its own criminal offence since 2021. It requires no particular level of force and no injury whatsoever.
And consent is not always a defence.
Where serious harm results, consent is not a defence — meaning “she asked me to” is not an answer the law accepts.
AND THE ACTUAL GRABS
Nobody has tested a single release.
There is no outcome study for any grip release or hold escape — not the thumb-gap principle, not anything else.
That is all we can tell you.
It appears in instructional material and nowhere else. It is plausible and it is widely taught.
What practising alone actually buys.
Watching and repeating a movement by yourself changes how the movement looks, measurably and quite strongly.
Not whether it works on a person.
It changes whether the movement works on a person essentially not at all.
Their skills fell apart.
When trained police officers faced an actual threatening human being instead of a pad, a kick that travelled 55cm in practice travelled 25cm.
Not a gap you can close with repetitions.
More martial arts training behind them did not protect against the drop.
So the drill after this is not graded, and what you do in it is not yet a skill. In the words of the researchers who study this for a living: practising alone is a supplement, not a substitute, for training with a live partner.
