Wait for the Half-Life
Ninety seconds. Let the chemistry finish. Then decide.
When a strong emotion hits, note the time. The neurochemical surge driving it lasts roughly 90 seconds. After that, anything you're still feeling is being re-triggered by your own thinking. At the 90-second mark, check: is the feeling fading or am I actively reigniting it with the story I'm telling?
You're in the grip of a strong emotional reaction — anger, panic, humiliation — and about to act on it.
The emotion is signalling genuine ongoing danger that requires sustained alertness.
Why it works
The initial neurochemical flood of any emotion has a natural half-life of about 90 seconds. Beyond that, you're choosing to re-trigger it — which means you can also choose to let it pass.
When an emotion fires, your body floods with a specific cocktail of neurochemicals — cortisol, adrenaline, norepinephrine. That cocktail has a biological half-life of roughly 90 seconds. After that window, the chemical surge is dissipating. If the emotion persists beyond 90 seconds, it’s because your thinking is re-triggering the same cascade: replaying the event, elaborating the story, imagining consequences. This is a predictable mental loop, not a character failure. But knowing the mechanism gives you a choice point. If you can ride out the first 90 seconds without acting or fuelling the narrative, the raw intensity drops naturally. Everything after that is optional.
