The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
Autoregulation is the way in which your vagus nerve makes sure that that seesaw of sympathetic nervous system to parasympathetic nervous system balance doesn't get tilted too far to the side of sympathetic nervous system activation, that your levels of alertness, your heart rate, your breathing rate, et cetera, don't get too high.

Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The vagus is involved in lots and lots of things. It's not just for calming down. It's also for slowing the heart rate, which is related to calming down, but it's critically required for this thing that we're calling autoregulation, for increasing HRV. It's also involved in increasing levels of alertness, and you can do that through exercise.
