Areas › Anger › Cool the body first
A sigh opens the chest and drops the guard for a second. That is part of why it feels like relief and part of why the other person softens too.
Anger holds the body braced: shoulders up, chest closed, everything protecting the middle. A sigh undoes some of that, and it is hard to keep the fighting posture while it happens. If someone is watching you, they see it as well, which is often the first sign to them that this is coming down rather than going up.
Qur’an and Sunnah
Did We not relieve your heart for you (Quran 94:1). The pressure in the chest is taken seriously as something that needed easing, which is exactly where a sigh lands.
أَلَمۡ نَشۡرَحۡ لَكَ صَدۡرَكَ
Did We not relieve your heart for you [Prophet]

What the research says
The account of a sigh as a signal of dropped guard is a plausible story rather than a tested one, and it should be labelled that way. What has been tested is the wider approach: a network meta-analysis found several body-based relaxation methods reduced occupational stress in healthcare workers, with none of them clearly ahead. Working through the body has support; this particular explanation of why is speculation.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
The braced shape and the sighing shape cannot both happen at once, so one of them has to give.
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
Anger has a shape you can learn: jaw tightening, breathing heavier, heat in the face, and often a strange busyness in the hands. Find your own two or three.
If you notice a hard locked stare, in yourself or in the room, look away. Empty space is the safest thing to look at, because it says nothing back.
While you drink, follow the cold going down the back of your throat. It turns a sip into half a minute of attention resting somewhere other than the argument.
