I think it depends on how close to full choking you get. Gentle to moderate, broadly dispersed “chokingesque” pressure is fine as it doesn’t significantly interrupt blood flow. Using enough force or concentrating force to occlude the carotid arteries is asking for trouble.
Not only is there the risk of ischemic brain damage, the carotid sinus, located where pressure is often placed, is prone to arterial plaque formation due to increased turbulence. Disrupting those plaques can break them loose, causing a stroke. That’s how a mate of mine lost much of the use of his right arm, though I suspect he wasn’t getting choked out. Never asked though.


BDSM can skirt some safety lines. It’s generally easy or at least quite obvious how to be safe if you know what you’re doing, so ignorance or extreme behavior are usually what get people in trouble.
The more minor incidents do make for great stories if you know anyone who works in A&E. “I tripped and fell on a courgette.” Sure you did, love.
