Recognize the difference between titration and flooding

Learn to distinguish "processing within the window" from "flooding outside it" — the difference determines whether the session helps or harms.

Why it works

Within the window of tolerance: sensation is uncomfortable but observable, the self feels present, language and thinking remain available, and there is some sense of being able to choose attention. Flooding: sensation becomes overwhelming, dissociation begins, narrative fragments or disappears, affect is uncontrollable, or time distorts. Recognizing the difference in real time is the core skill of titration. Flooding is not "deep work" — it is the signal that the dose has exceeded capacity and is more likely to reinforce dysregulation than to process it.

How to do it

1. Before difficult sensation work, establish your "I can track this" markers: still present, can speak, can choose.
2. During: notice if any of those markers drop. If you can’t find words, you’re near the edge.
3. If flooding begins: move immediately to the resource, breathe, orient to the room.
4. Treat flooding as information about dose, not failure — reduce next time.

Evidence

Flooding and retraumatization from high-intensity exposure are recognized risks in trauma therapy; maintaining within-window processing is a core principle of trauma-informed care. (clinical)

Distinguishing titration from flooding in real time requires practice and, ideally, a trained practitioner. Self-monitoring has limits — dissociation can present as "doing fine" until it is obvious.

Common mistake

Misidentifying flooding as "deep processing" and continuing rather than retreating. Tearfulness, fragmented language, or feeling "not there" are signals to stop, not signals to push through.
