The 90-Second Rule

There's an idea that gets repeated a lot in wellbeing circles: that an emotion, left alone, lasts about ninety seconds. Everything after that, the claim goes, is you keeping it alive.

It's a genuinely useful idea. It's also worth being straight about where it comes from.

Where the idea comes from

The ninety-second figure is most associated with the neuroanatomist Dr Jill Bolte Taylor, who described it in her book My Stroke of Insight. Her account is that when an emotion is triggered, the associated chemical response runs its course through the body in roughly a minute and a half — and that if the feeling persists beyond that, it's because we are continuing to re-trigger it with our thoughts.

Honest caveat: this specific ninety-second figure comes from a clinician's description rather than a large body of replicated experimental research. Treat it as a useful rule of thumb, not a precise physiological law. The broader principle behind it — that ruminating on a feeling extends it — is far better supported.

The part that genuinely holds up

Whatever the exact number, the mechanism it points at is real and well-studied: rumination prolongs distress. Turning a feeling over repeatedly, re-telling yourself the story, asking "what if" again and again — this reliably extends and intensifies emotional states rather than resolving them.

That's the practical insight worth keeping. The wave itself is short. The re-telling is what makes it an afternoon.

How to use it

Next time anxiety arrives, try this:

1. Notice it and name it. "That's the wave." Naming creates a small gap between you and the feeling.
2. Let it be physical for a moment. Where is it? Chest? Stomach? Throat? Attending to the bodily sensation rather than the story is the whole trick.
3. Don't add the narrative. No "this is awful", no "what if it goes wrong", no rehearsing. Those are the top-ups.
4. Give it a minute or two. Breathe out slightly longer than you breathe in.

You will not always manage this, and that isn't failure. The aim isn't to never feel anxious — it's to stop automatically pouring petrol on it.

If the wave doesn't pass

Some anxiety isn't a passing wave, and no breathing technique should be expected to fix it. If anxiety is persistent, interfering with your work, sleep or relationships, that is worth a conversation with your GP rather than another article. The support page lists UK services that can help, including free NHS talking therapies you can often refer yourself to.

For the everyday version — the spike before a meeting, the dread on a Sunday evening — this is a genuinely useful thing to have in your pocket. Ride the wave. Don't narrate it.
