The email lands at 4:52 on a Friday. Subject line: re: summer schedule. Three paragraphs, one of them containing the phrase as we discussed, describing a conversation that did not happen the way it is being described.
Within about twenty seconds she is hot across the chest, her thinking has narrowed to a point, and she has begun composing a reply that will take four hours to write and will make everything worse.
What is actually happening
Flooding is physical before it is anything else. Heart rate climbs, the body prepares for effort, and the more deliberate, nuanced part of thinking becomes considerably harder to access — not gone, but expensive and unreliable.
Two consequences follow, and both matter more than they sound.
The first is that you are, briefly, not in possession of your best judgement. That is not a moral statement. It is a description of resource availability.
The second is that flooding does not know the difference between a threat to your life and a badly worded email about July. The machinery is old and it is not a close reader.
Why the reply written now is the wrong reply
Everything that makes a message effective in a co-parenting exchange — brevity, precision, not taking the bait, an eye on how it looks if a third party ever reads it — depends on exactly the capacity that is least available in the first few minutes.
So the reply composed at 4:53 tends to be long, to relitigate three previous incidents, and to contain one sentence that will be quoted back at you for a year. Not because you are inarticulate. Because you were writing while flooded, which is a bit like proofreading while sprinting.
The wait is the technique
The intervention is unglamorous and it is mostly time. Physiological arousal of this kind subsides on its own if it is not fed — and reading the email again is feeding it.
What helps the wait pass:
Change your physical state. Stand up, go outside, walk to the end of the road. Movement gives the mobilised state somewhere to go.
Lengthen the out-breath. Not deep breathing in general — specifically making the exhale longer than the inhale, which nudges the system towards settling.
Cool water. Cold water on the face or wrists is a crude but reliable lever on a body that has heated up.
Do not re-read it. The single most common mistake. Each re-read restarts the response.
Then reply tomorrow morning. Almost nothing about a summer schedule requires an answer inside an hour, and the small number of things that genuinely do are usually phone calls, not emails.
Two sentences for the ones you cannot leave
Where an acknowledgement really is needed, it can be short enough to write while flooded without damage: Got it — I will come back to you on this tomorrow.
That is complete. It concedes nothing, argues nothing, and buys the time in which the actual reply can be written by somebody with their full range available.
One thing you can do this week
Decide, in advance and in writing, what your rule is. For example: his emails get opened once, and answered the following morning.
Deciding in advance is the whole trick, because the decision cannot be made well in the moment — the moment is precisely when your judgement is least available. A rule made on a calm Tuesday is doing a favour for a version of you who will be in no state to make it.
The short version
- Flooding is a physical state that temporarily reduces access to careful thinking.
- The machinery does not distinguish a real threat from a badly worded email.
- A reply written in the first minutes is reliably worse than one written later.
- Movement, a longer out-breath, cool water and not re-reading all shorten it.
- A rule decided in advance protects you at the moment you cannot decide well.

Frequently asked questions
What is emotional flooding?
It is a state of high physiological arousal — raised heart rate, narrowed attention, the body preparing for effort — during which access to careful, nuanced thinking is substantially reduced. It is a physical event rather than a lapse in composure.
How long does it take to calm down after being triggered?
There is no single figure, and it varies by person and situation. What is consistent is that the state subsides on its own if it is not fed, and that re-reading the message restarts it. Building in a delay is more effective than trying to think your way out.
Should I reply to my ex right away?
Usually not. The qualities that make a co-parenting message effective — brevity, precision, not taking bait — depend on exactly the capacity that is least available in the first minutes. A short acknowledgement now and a full reply tomorrow generally produces a better outcome.
What is the fastest way to calm down?
Changing physical state helps most: standing, walking, cool water on the face, and making the out-breath longer than the in-breath. None of these are cures; they shorten the period during which you are not at your most capable.
