Breathe in for about five and out for about ten, and do not hold at the top. Go straight from the in breath into the out breath, five to ten times over.
That pause after the inhale feels natural to add, and it can raise your heart rate rather than lowering it, which undoes what you came for. If ten counts out is too long, shorten both numbers and keep the ratio. An easy way to remember the direction: the out breath is the peaceful one.
Qur’an and Sunnah
Did We not relieve your heart for you (Quran 94:1). The picture is of something tight being opened out, which is close to what a long unhurried exhale feels like from the inside.
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, and the pattern built around a long exhale gave the largest gain in mood. In a smaller crossover study, deep slow breathing raised pain thresholds and increased gut motility, both signs of a genuine shift in the calming branch of the nervous system. Neither tested the instruction about not pausing, which comes from clinical practice rather than trial evidence.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
Your body eases off while you breathe out, so making that half the longer one tips the whole cycle in the same direction.
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
Let the in breath come however it comes, then breathe out through pursed lips as though through a straw for a count of eight, finishing with two more counts through the nose. Three ordinary breaths, then go again.
Four in, hold four, four out, hold four. The holds are the strong part of this one, and they stay optional every single time.
