Other people need to practice long exhale breathing in order to build up vagal tone, something that's very useful to do, whether you're grieving or not.
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.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
So if people can't remember like what breath work to do physiological side, just emphasize an exhale. Extend it. Make it a little bit more vigorous. If you need to be covert about it, maybe just extend it a little bit. Maybe walk back to the podium or away and do that long exhale. That seems to really make a big difference because you're offloading carbon dioxide. But also there's this pathway through the vagus nerve that literally slows your heart rate down when you exhale. It's pretty spectacular that we have these mechanisms in us.
