How to calm down after an argument

To calm down after an argument, take a real break of at least 20 minutes so your stress response can settle, slow your breathing to about six breaths per minute, name what you’re feeling in words, and add bilateral stimulation — slow left-right taps or eye movements — to help the replay loosen its grip.

The door just closed, or the call just ended, and your heart is still pounding. You’re re-running the whole thing on a loop: what they said, what you said, the three better comebacks you’ve thought of since. You know staying angry isn’t helping, but “just let it go” has never once worked on a body that feels like this.

That’s not a character flaw. It’s physiology, and physiology is something you can work with directly.

Why do you feel so wired after an argument?

Conflict with someone you care about registers in your body as a threat. Your sympathetic nervous system signals the release of adrenaline, your heart rate climbs, and blood is redirected toward the large muscles you’d need for fighting or fleeing (American Psychological Association, 2024).

Researchers John Gottman and Robert Levenson measured couples’ physiology during conflict for decades and found this arousal at the center of arguments that go badly (Journal of Personality and Social Psychology, 1992). Gottman’s team calls the extreme version “flooding”: once your heart rate passes roughly 100 beats per minute in a conflict, you get what they describe as “tunnel-vision and tunnel-hearing” — your brain effectively can’t process social interaction anymore, so real listening and problem-solving become next to impossible (The Gottman Institute, 2015).

You’ve probably felt this from the inside. Past a certain point, you’re not discussing anything anymore; you’re just defending. If that swamped, overloaded feeling is familiar even outside arguments, our page on anxious feelings and bilateral stimulation goes deeper into it.

In other words, the argument pushed your arousal past the point where you can think clearly and feel your feelings at the same time. Everything below is about bringing that arousal back down. Nothing productive happens until you do.

The 10-minute reset to calm down after an argument

Here’s a concrete sequence you can start the moment you have a little space to yourself. The first step sets the container: a break of at least 20 minutes. The next three are the 10-minute reset itself, done inside that break; whatever time is left can be a walk, a shower, music. If what you’re feeling is mostly heat rather than hurt, we also have a faster reset for calming down.

Step 1: Take a real break (and don’t rehearse)

Gottman’s research puts a number on the cooldown: after flooding, your body needs at least 20 minutes to return to baseline, and the break shouldn’t stretch past 24 hours before you circle back (The Gottman Institute, 2015).

The catch is what you do with those minutes. If you spend them drafting your rebuttal or cataloguing their offenses, you’re re-triggering the same stress response and the clock keeps restarting. A break only counts if it’s genuinely soothing: the steps below, a walk, a shower, music. If your head keeps dragging you back into the loop, that’s normal, and it’s exactly what steps 3 and 4 are built for.

Step 2: Slow your breathing to about six breaths per minute

Your breath is the most direct lever you have on an activated nervous system. A 2018 systematic review in Frontiers in Human Neuroscience looked across studies using slow breathing, roughly in the four-to-ten-breaths-per-minute range, and found it generally associated with a shift toward parasympathetic (rest-and-digest) activity, with participants in various studies reporting increased relaxation and reduced tension, anxiety, and anger. Six breaths per minute, the pace below, falls within that range and is one of the easier tempos to count.

Six breaths per minute works out to roughly a 4-second inhale and a 6-second exhale. Set a timer for three minutes and just count. You don’t need to empty your mind; you need to lengthen your exhale.

Step 3: Name what you’re actually feeling

Under the anger there’s usually something more specific: dismissed, embarrassed, scared, unappreciated. Finding the word matters more than it seems. In a 2007 fMRI study in Psychological Science, Lieberman and colleagues found that labeling an emotion in words dampened activity in the amygdala, the brain’s alarm center, compared with other ways of engaging the same material.

Say it plainly, out loud or on paper: “I feel dismissed, and my chest is tight.” One honest sentence. That’s affect labeling, and it’s doing real neurological work.

Step 4: Add bilateral stimulation while you hold what’s left

Once the sharpest edge is off, there’s usually a residue: the scene that keeps replaying, the sting of one particular sentence. This is where bilateral stimulation (BLS), the left-right rhythmic technique at the core of EMDR therapy, is worth trying.

The simplest manual version is the butterfly hug:

1. Cross your arms over your chest, hands resting on opposite upper arms.
2. Bring the argument to mind loosely, without narrating it. Just let the scene be there.
3. Tap left, right, left, right, slowly, for 30 to 60 seconds.
4. Pause, take one slow breath, and notice what shifted. Repeat 3 to 5 times.

Why would tapping help? The leading explanation is working memory: holding a memory in mind while tracking a left-right rhythm gives your brain two jobs at once, and the memory tends to lose vividness in the process. A 2013 meta-analysis of 26 studies in the Journal of Behavior Therapy and Experimental Psychiatry found significant effects for eye movements on emotional memories, moderate in clinical EMDR trials (d = 0.41) and large in laboratory studies (d = 0.74).

To be straight with you: the evidence is strongest for eye movements, since tapping is less studied, though it uses the same left-right principle, and the research is mostly about memories rather than fresh arguments specifically. But a 20-minute-old argument is already a memory you’re replaying, and the same working-memory mechanism plausibly applies.

If you’d rather be guided than count taps yourself, EmEase, a self-guided EMDR app, runs the same technique with a moving on-screen target or alternating audio tones, at whatever pace suits you, in the web app. For the full technique, including eye-movement and audio variations, see our introduction to bilateral stimulation.

Should you restart the conversation?

Yes, ideally within 24 hours, and only once you can think about the other person’s side without your chest tightening. That’s your sign your arousal has settled back down. Coming back calm isn’t conceding the point; it’s the only state in which the point can actually land.

When a reset isn’t enough

This protocol is built for the ordinary, bruising arguments of life with other humans. Some situations need more than a reset:

• The same fight keeps recurring and leaves you flooded every time. A couples or individual therapist can help you find the pattern underneath it, especially if that reactivity shows up in more than just this relationship.
• Arguments regularly pull up old, painful material from your past. Processing that is best done with a trained professional rather than on your own.
• You feel unsafe in the relationship, physically or emotionally. That’s not a regulation problem, and calming techniques aren’t the answer to it.

And if your mind keeps looping the argument on replay, our page on how to stop racing thoughts has more ways to quiet that spiral.

The argument already happened. The next 20 minutes are yours.
