The physiological sigh: a double inhale to reset quickly
A physiological sigh is a double inhale - a normal breath in, then a second short sip on top - followed by a long, slow exhale. Research suggests a few of these in a row can lower arousal quickly, making it a handy in-the-moment reset.
It is a natural pattern your body already does. A few rounds is enough; it is not meant to be a long practice.
The rhythm
| Phase | Seconds |
|---|---|
| Inhale | 3s |
| Inhale (top-up) | 2s |
| Exhale | 7s |
A full inhale, a short top-up inhale, then a long exhale. Repeat one to three times.
How to do it
- Inhale through the noseA normal, comfortable breath in.
- Add a second short inhaleA small sip on top to fill the lungs.
- Long, slow exhaleLet it out slowly through the mouth. Repeat one to three times.
Common uses
- A fast reset when stress spikes.
- Taking the edge off a wave of anxiety.
- A quick pause between tasks.
What the evidence suggests
A 2023 controlled study found that five minutes of daily cyclic sighing improved mood and lowered respiratory rate more than mindfulness meditation over one month. It is promising early evidence from one study - not a cure-all.[1]
Safety
A gentle, hold-free technique. Keep the breaths comfortable rather than gasping the second inhale.
Beginner version
One round - double inhale, long exhale - is a complete practice. Add a couple more if you like.
