Four in, hold four, four out, hold four. The holds are the strong part of this one, and they stay optional every single time.
Some people find the pauses deeply settling. Others meet the edge of what they can tolerate there, especially at the bottom of the exhale. Both are ordinary. If the next breath starts to feel urgent, let the holds go and keep the even count, which loses you nothing that matters.
Qur’an and Sunnah
God does not burden any soul with more than He has given it (Quran 65:7). If the holds are more than you have today, dropping them fits that rather than falling short of it.
لِيُنفِقۡ ذُو سَعَةࣲ مِّن سَعَتِهِۦۖ وَمَن قُدِرَ عَلَيۡهِ رِزۡقُهُۥ فَلۡيُنفِقۡ مِمَّآ ءَاتَىٰهُ ٱللَّهُۚ لَا يُكَلِّفُ ٱللَّهُ نَفۡسًا إِلَّا مَآ ءَاتَىٰهَاۚ سَيَجۡعَلُ ٱللَّهُ بَعۡدَ عُسۡرࣲ يُسۡرࣰ ا
and let the wealthy man spend according to his wealth. But let him whose provision is restricted spend according to what God has given him: God does not burden any soul with more than He has given it- after hardship, God will bring ease

What the research says
Pooling 58 randomised studies, training people to breathe slowly with heart rate feedback gave a small to moderate benefit across a wide span of emotional and physical complaints. Those studies were about slow paced breathing rather than breath holding, so the box pattern with its two pauses is not the thing that was tested. The general direction has support behind it. This particular shape is a reasonable extension of that and no more.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
Holding the breath changes the chemistry that drives the urge to breathe, which is why a pause feels like so much more than a gap.
When not to
Leave the retentions out if you are prone to panic, or pregnant, or have been told to take care with your blood pressure.
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
The soft sound and the feel of this breath in your throat give your attention somewhere to sit. When the mind is loud, something you can hear holds better than something silent.
The fast forceful practices are not for everyone. With high blood pressure, heart trouble or glaucoma, leave them out and use the slow ones, which carry no such warning.
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.
