There is however, a way in which you can breathe that directly controls your heart rate through the interactions between the sympathetic and the parasympathetic nervous system.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

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.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
I want to make sure that I mentioned that breathing controlling heart rate through the sympathetic and parasympathetic nervous system is the basis of what's called HRV, heart rate variability.
So, if you want to calm down quickly, you need to make your exhales longer and or more vigorous than your inhales.
Your breathing can directly impact your heart rate and your level of stress or calm. Here's how it works.
And that's what's called respiratory sinus arrhythmia. That's the technical phrase. It's also the basis of what's called heart rate variability or HRV
So the relationship between breathing and heart rate is an absolutely lockstep one where your heart rate follows your breathing. Your heart rate and your breathing are in an intimate discussion with one another, but where always and forever your inhales increase your heart rate, your exhales decrease it.
