Cutting off oxygen to the brain is clearly and obviously a dangerous thing to do, and one should expect brain damage from doing so, especially serially, and regularly.

Unless the brain and body were on serious ice, and even then...

This may explain, in part, why individuals in the BJJ community often act in goofy and impulsive manners.

Let alone if they have also had a lot of concussions...

The more of the population I meet the less I think this will affect them.

This study is relevant. It seems to suggest that choking each other may actually increase some neuroprotective stuff. Unless I'm reading it incorrectly.

Very small sample size comparison groups....

Yeah I'm just not aware of many studies about choking in relation to grappling other than that one. I've always felt it's bad for us to get choked, but probably only really bad if it's near or to the point of unconsciousness. If there was a study that definitively proved that we are causing ourselves long term health issues by choking would you stop?

Judo researchers did bunches of them in the decades prior to 2000.

The problem is Judo studies, particularly out of Japan, are famous for failing to report negative outcomes, and for omitting negative outcome data.

I have known over a dozen people who have had strokes on the mats, and I switched to catch and release on chokes over a decade ago (or more).

For that matter, I am catch and release on most (all) submissions.

When you are the highest ranked person in the room, it is embarrassing if people get injured or harmed, and you are the training partner...

Then there is this guy, so who can say:

I can’t believe I actually read all the comments on this subject. I don’t know how, but I have to get back to my life.

Comments where? All the eight replies here?

So this choking during sex business ... Carotid choke until they almost pass out? Where can I find an instructional ... asking for a friend lol

If no tools are used, my friend is more interested in hearing about if the choking and the... funny business is done simultaneously and, if so, what choke in combination with what funny business? How do they even solve that mechanically besides some white belt Homer Simpson choke?

Assuming the chokee is also the primary funny business receiver and there's not an extreme difference in height, perhaps a triangle, leg scissor or gogoplata would be the most practically viable options (none would involve mid parts acquainting, but other options). Which is really not what I think the typical bed choker is practicing.

My suspicion is that it's mainly the (from a BJJ practitioner's viewpoint) most vanilla Homer Simpson chokes you could think of, which no one with basic knowledge of chokes would ever tap to. But done between people who really do not have the basic knowledge of chokes and thus no developed concept of choke safety, which then would still make it so much more dangerous than us choking each other every other day on the mat. So not vanilla for them, but they are really the last people who should do that stuff. But perhaps the lack of deeper knowledge is also part of the appeal for them, making it feel more forbidden and tantalizing in a power play manner (giving up control or having someone give up control for them to do something which they themselves perceive as freaky, as they don't have a more clinical knowledge of it). So the ones most suitable to do any of that (if anyone) are perhaps also less likely to be into it.

Keep in mind that articles like this on sites like psypost.org - while they may be accurate in many respects - are not peer reviewed by the scientific community in the same way something in a scholarly medical journal like the Lancet would be. These articles are intended to provide general information for consumption by laypeople. While the words of medical professionals should always have some level of deference, this portion is key: "Science has yet to definitively prove that occasional, low-force neck compression causes permanent brain damage. Still, the early indicators warrant caution." I am an attorney and know exactly why this sentence is there: the author is making sure he avoids a frivolous lawsuit while pointing out the risks of choking during sexual activity.

Without getting crude, it should be understood the Brazilian jiu-jitsu and sex occur in different context and different environments. One involves supervision by professionals and the other typically does not (but to each his or her own - I'm not judging). Additionally, one of these activities involves people being trained how to apply a choke correctly while the other involves people who may have never choked or been choked before....experimenting in a moment of passion.

I purchased this article in the course of my law practice to defend a case: https://pubmed.ncbi.nlm.n[...]/38857060/

I cannot provide an unpaid link to it for copyright reasons but the publicly available abstract does a good job summing it up. For context, I was defending a person who used BJJ in self defense where the police and prosecutors thought the force used was excessive and wanted to stress in trial that the 'victim' could have died over a bar fight. I successfully argued to the judge that such insinuations were not "public knowledge" and the state should be required to produce expert testimony to that effect before being permitted to make such arguments. The judge agreed and ordered them not to say that unless it came out in evidence during their case. They ultimately gave my guy a misdemeanor deferred instead of a felony which keeps the whole thing off his record if he stays out of trouble for 15 months.
