A breathing technique for rapidly calming anxiety symptoms before or during speaking. The key insight is that the relaxation response happens on the exhale, so you deliberately make the exhale about twice as long as the inhale. Abrahams jokingly calls this the 'rule of lung'.

Origin

Abrahams presents this as one of many breathing variations (box breathing, etc.) rooted in deep belly breathing from practices like yoga and Tai Chi/qigong. In the conversation it connects to embodied-cognition research and a guest, Johnny Miller, who taught related work.

Core principles

  • 01Deep belly breathing slows heart rate, normalizes the voice, and reduces shakiness
  • 02There are many ways to inhale and exhale; what matters for relaxation is a long exhale
  • 03The magic of the relaxation response happens during the exhale, not the inhale
  • 04Longer exhales pull you into the present moment and out of future catastrophizing

How to run it

  1. 1

    Take a full inhale

    Breathe in with a belly breath until you feel completely full, optionally sneaking in a little extra air at the top.

    Pro tip The double-inhalation top-up fills additional capacity in the lungs and enhances the calming effect.

  2. 2

    Exhale twice as long

    Release the breath slowly so the exhale lasts roughly twice the count of the inhale (e.g. a three-count in, a six-count out).

    Watch out The inhale style matters far less than the exhale length; do not obsess over how you breathe in.

  3. 3

    Repeat a few cycles

    Do several rounds until your body feels physiologically less stressed and your attention is anchored in the present.

In the wild

Fast, noticeable calming

Lenny reports that although breathing differently sounds trivial, both the research and his own experience show it works very quickly; after a few rounds he feels really different.

A rapid, repeatable drop in felt nervousness within a minute or two.

Common mistakes

Focusing effort on the inhale

People fixate on how to breathe in, but the relaxation response is driven by the long exhale, so a short exhale wastes the technique.

Is it for you?

Best for

Speakers in the one minute before and the first minute of speaking, when nerves peak and a fast physiological reset is needed

Not ideal for

People who need deeper or sustained anxiety work; this is an acute in-the-moment tool, not a standalone cure
