Physiological Sigh

A double inhale reopens the lungs; a long exhale slows the heart. One to three minutes is enough. Press Start and breathe with the circle.

How it works

The double inhale reopens collapsed air sacs in the lungs and helps clear carbon dioxide faster. The long exhale engages the vagus nerve, so your heart slows with every breath out.

What research found

In a Stanford study (Balban et al., Cell Reports Medicine, 2023), five minutes of cyclic sighing a day improved mood and lowered breathing rate more than mindfulness meditation.

When to use it

  • At the first signs of panic
  • Before a hard conversation or call
  • When your heart is racing after a trigger
  • Before sleep, to let the day go
