A “physiological sigh”: a breath in through the nose, a short second sip of air on top, then a long, slow breath out through the mouth.

Why it may help

People sigh naturally when they need to reset. Doing it on purpose, with a long exhale, is a quick way to ease tension. A small study found a few minutes of it daily lifted mood.

When to use it

• when you need to calm down in under a minute
• when you notice your chest feels tight
• between tasks, as a quick reset

Helps with

• Quick calming
• Tension

How to do it

1. Breathe in through your nose, then take a short extra sip of air on top.
2. Follow the circle: in, then a long, slow breath out through your mouth.
3. Let your breathing settle naturally for a few breaths. (about 15 seconds)

Breathing pace: in for 3 seconds, hold for 1, out for 6 — 5 rounds.

What the evidence says

Emerging evidence: Early or mixed research looks promising, but it is too soon to be confident. Treat it as worth trying, not proven.

What was found

A 2023 study found that five minutes a day of cyclic sighing improved mood and reduced breathing rate over a month, more than a mindfulness comparison group.

What is uncertain

This is one relatively small study, so the finding needs repeating before it can be called established.

Who it may not suit

If deep breaths make you light-headed, take smaller breaths or stop. Anyone with a breathing condition may prefer gentler slow breathing.

Where this comes from: Slow-breathing and breathwork research.

Afterwards, ask yourself

How quickly did the sighs change how you felt?
