Breathe in

Follow the shape: it grows as you breathe in and shrinks as you breathe out.

How to do it

  1. Breathe in through your nose for 4 seconds.
  2. Hold the air for 4 seconds, shoulders relaxed.
  3. Breathe out gently through your mouth for 4 seconds.
  4. Stay empty for 4 seconds, then start again.

What it does

  • Slows down your breathing
  • Brings your attention back to the moment
  • Easy to do discreetly, anywhere

In the app, this technique is guided by a voice, its own animation and ambient sounds. To create your own rhythm, use BreathLab.
