Physiological sigh: a 90-second stress reset you can do at your desk
A physiological sigh is a breathing pattern of two inhales through the nose followed by one long, slow exhale through the mouth. Repeating it for 90 seconds to 5 minutes is one of the fastest ways to feel calmer at your desk. In a 2023 Stanford randomized trial, daily “cyclic sighing” improved mood and lowered breathing rate more than mindfulness meditation.
How to do it, step by step
- Sit upright with both feet on the floor and relax your shoulders.
- Breathe in slowly through your nose for about 2 seconds.
- Without exhaling, take one more short “top-up” sip of air through the nose (about 1 second).
- Exhale slowly through your mouth for about 6 seconds, longer than both inhales combined.
- Repeat for 90 seconds (about 10 rounds). Keep it gentle — no forcing.
Why it helps
- Calms you down in real time, before a meeting or after a tough email
- No equipment, no one notices you doing it
- Exhale-focused breathing is linked with a slower breathing rate
When to use it at work
- Right before a presentation or difficult call
- When you notice your heart racing at your desk
- As a 90-second break every hour
Frequently asked questions
How long should I do the physiological sigh?
One to three sighs can take the edge off in the moment. For a fuller reset, repeat for 90 seconds. The Stanford study used 5 minutes a day.
Is the physiological sigh better than box breathing?
In the 2023 Stanford trial, cyclic sighing produced the largest mood improvement of the techniques tested, but box breathing also helped. Use whichever you will actually do.
Can I do it in an open-plan office?
Yes. Keep the exhale quiet through slightly pursed lips — it looks like normal breathing.
