Extended Exhale
In for four, out for six. The simplest version of the longer-exhale idea.

What it is
This is belly breathing with the ratio made explicit: the out-breath is one and a half times the in-breath. Nothing is held, nothing is forced, and it can be done anywhere without anyone noticing.
Why a long exhale calms you
Vagal activity — the braking system on your heart rate — rises during the out-breath and falls during the in-breath. Lengthening the exhale means more time with the brakes on. Subjectively this shows up as a loosening in the jaw, shoulders and stomach, usually within a minute or two.
It is also the mechanism behind sighing, which is your body doing a crude version of this automatically.
When to use it
Good for the ten minutes before a difficult conversation, after an argument, or when anxiety is background hum rather than acute panic. If you are in acute panic, use the Panic Anchor instead — it is deliberately even simpler.
How to do it without the app
- Sit or lie down and let your shoulders drop.
- Breathe in through the nose for 4 seconds.
- Breathe out through pursed lips for 6 seconds.
- Do not pause or hold at either end.
- Continue for 4 to 6 minutes.
Safety
- Safe for most people. No breath-holding.
- If pursed-lip exhaling makes you cough, breathe out through the nose instead.
What the evidence says
Exhale-lengthened breathing has been repeatedly shown to raise vagally mediated heart rate variability and reduce self-reported state anxiety in short laboratory sessions. Longer-term effects are less well studied.
