Cyclic sighing

Five minutes a day of double-inhale, long-exhale breathing. Cheap, low-risk, quick.

How it works

Two inhales through the nose — a full one, then a short top-up — followed by a long, slow, complete exhale through the mouth. Repeat for five minutes. The emphasis on the extended exhale is the active ingredient in the tested protocol. This is a base-layer habit, not a worry technique: use it daily on a schedule rather than reaching for it mid-panic, which turns it into another safety behaviour.

How good is the evidence

Preliminary evidence

Balban et al. (Cell Reports Medicine, 2023;4(1):100895, n=111) found exhale-focused cyclic sighing produced greater mood improvement and greater respiratory-rate reduction than mindfulness meditation over one month of 5 min/day.

Caveat: Small, one month long, self-report primary outcomes, no significant HRV change, and the senior author disclosed becoming an advisor to a wearables company during the study period. A cheap low-risk tool with promising-but-early evidence — not a cure.

• Worry triage — Sort each worry into one you can act on today and one you cannot. They need opposite treatment.
• Worry postponement — Capture worries as they arrive, and deal with them only in a fixed daily slot.
• Detached mindfulness — Notice a thought arrive, and take no action on it whatsoever — including not arguing with it.
• Decatastrophising — Realistic worst case, most likely case, and — the part people skip — how you would actually cope.
