If you keep only one thing, make the out breath longer than the in breath. Four in and eight out is enough, and nothing clever is needed on top of it.
This is the closest thing to a dependable settling lever. It suits the end of the day, a queue you are stuck in, the ten minutes before sleep. Some people add a pause after the inhale and find it deepens the effect. Others find that same pause wakes them up, so try it both ways before you decide which one is yours.
Qur’an and Sunnah
Did We not relieve your heart for you (Quran 94:1). The question is put to someone whose chest had been tight, and the relief is described as done for him rather than managed by him.
أَلَمۡ نَشۡرَحۡ لَكَ صَدۡرَكَ
Did We not relieve your heart for you [Prophet]

What the research says
In a month long randomised trial, five minutes a day of structured breathing lifted mood and slowed resting breathing more than mindfulness meditation did, and the version built around a long exhale produced the biggest gain in mood. Separately, healthy adults who practised slow paced breathing for 30 days reported better sleep and showed higher cardiac vagal activity than a group who scrolled social media instead. Both are modest studies in fairly healthy people, so take them as encouraging rather than settled.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
The braking system on your heart does most of its work while you breathe out, so a longer out breath gives it longer to act.
This one is still a draft. It is waiting on a scholar and a clinician to read it before it is published.
Near this one
If big breathing feels like too much, make it smaller instead. Breathe so smoothly that the in breath rolls into the out breath with no sound and no edges.
When you are flat rather than wound up, try this. Rub your palms together until they feel awake, let them rest, then breathe in as your arms lift and out as they lower, two or three times.
Fighting, running and freezing are the ones everybody can name. There is a fourth: going along with things, smoothing them over, making yourself easy to be around so that nothing bad happens.
