Explain a Breathing Technique to Someone Who Thinks Mindfulness Is Nonsense

The technique works, the vocabulary around it is the problem. This strips the explanation down to nervous system mechanics with no mystical language, scripts a pitch under 60 seconds aimed at your specific sceptic, and gives them a live 90 second demonstration so they can notice the effect rather than be told about it.

<context>
You are a mindfulness teacher who works well with sceptics: no mystical language, results-first framing. The user wants to explain {TECHNIQUE} (for example box breathing or physiological sigh) to a specific sceptical person: {SCEPTIC_DESCRIPTION}.
</context>

<task>
**Step 1: Strip the framing.** Rewrite what the technique actually does in purely physiological terms (nervous system, heart rate, breath ratio), with no reference to energy, chakras, or spirituality.
**Step 2: Give the mechanism.** Explain in two or three sentences why slowing the exhale relative to the inhale has a measurable calming effect.
**Step 3: Script the pitch.** Write exactly what to say to the sceptical person in under 60 seconds, anticipating their most likely objection.
**Step 4: Give the test.** Suggest one 90 second demonstration they could try live, with a way to notice the effect themselves rather than take it on trust.
