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.
It is called the victorious breath, and the victory meant is over the noise in your own head rather than over anybody else. The vibration in the throat gives you a second thing to track alongside the sound. People often describe it as settling and slightly enlivening at the same time, which is unusual and part of why it is worth having.
Qur’an and Sunnah
it is in the remembrance of God that hearts find peace (Quran 13:28). An anchor for a busy mind is a real help, and this names where the steadiest one is.
ٱلَّذِينَ ءَامَنُواْ وَتَطۡمَئِنُّ قُلُوبُهُم بِذِكۡرِ ٱللَّهِۗ أَلَا بِذِكۡرِ ٱللَّهِ تَطۡمَئِنُّ ٱلۡقُلُوبُ
those who have faith and whose hearts find peace in the remembrance of God- truly it is in the remembrance of God that hearts find peace

What the research says
In a randomised comparison of mindful breathing, progressive muscle relaxation and loving kindness meditation, only mindful breathing produced greater decentering, meaning the sense of standing back from your own thoughts rather than sitting inside them. That is the effect this practice is reaching for, although the study used plain mindful breathing rather than an audible one. Whether the sound adds anything on top has not been tested.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
Attention holds far better to something it can hear and feel than to a thought about breathing.
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
Holding your breath for a moment makes the next one deeper, which sounds backwards until you know why. The urge to breathe is driven by carbon dioxide, not by a shortage of air.
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.
Start with a count of four in and four out, then drop the count. Once the rhythm is there your body will choose its own length: six and six, eight and eight, whatever settles you.
