Everything hit at once. Let's slow it down.

Emotional flooding (John Gottman's term, developed in couples research) is a state in which emotional arousal overwhelms cognitive function — the heart rate rises above approximately 100 bpm, the prefrontal cortex (responsible for reasoning and perspective-taking) is significantly suppressed by stress hormones, and the brain operates primarily in threat-response mode. In this state, the ability to listen, to remember previous agreements, to consider another person's perspective, or to access nuanced language is genuinely reduced, not merely unwilling. It is a physiological state, not a character failing.

Gottman recommends a break of at least 20 minutes of genuine rest — no rehearsal of the argument, no continued conflict, no additional stressors — for cortisol and adrenaline to clear sufficiently for reasoning to return to baseline. Many people take 30 to 40 minutes. The common pattern of taking a "short break" of five or ten minutes and returning to a conflict rarely works because the physiological arousal has not cleared. A genuine break requires physical separation, distraction into something cognitively engaging, and an explicit agreement to return to the conversation rather than abandoning it.

Emotional sensitivity is a trait: the tendency to notice and respond to emotional stimuli more readily than average. It is not a threshold phenomenon — it means you feel things more intensely but retain cognitive function. Emotional flooding is a threshold phenomenon: below a certain arousal level, you function normally; above it, executive function is significantly impaired regardless of baseline sensitivity. Emotionally sensitive people may flood more quickly because they reach the threshold earlier, but the flooding state itself looks the same once it is reached — the distinction is in the trigger, not the experience.

A useful first step is naming it directly: "I am flooding — I need a break." This is not avoidance; it is physiological management. In couples and family therapy contexts, establishing a "flooding protocol" in advance — an agreed signal, a defined break length (usually 30 minutes minimum), and an explicit agreement to return — removes the interpretation that the break is abandonment or stonewalling. During the break: do something physically calming (walk, stretch), avoid rehearsing the argument in your head, and avoid continuing the conflict on a phone. Return when heart rate has genuinely returned to baseline.
