Moving within your window of tolerance

Choose movement intensity that produces sensation without triggering overwhelm or shutdown.

Why it works

Trauma narrows the window of tolerance — the arousal band within which information can be processed and integrated. Physical movement that goes too far outside that window (high intensity, prolonged holds) triggers hyper- or hypo-arousal rather than integration. Choosing intensity at the edge of the window — felt but manageable — is how exposure expands the window rather than re-traumatizing.

How to do it

1. Before moving, estimate your current arousal level (1 = shutdown, 10 = flooded; aim to start from 3–6).
2. As you move, watch for signs of hyper-arousal (sudden anxiety, hyperventilation, dissociation) or hypo-arousal (numbness, going blank).
3. When either appears, reduce intensity: shorter holds, gentler range of motion, eyes open if closed.
4. Stay at the reduced level until the signal clears before going further.
5. Track which movements reliably stay within your window — these are your anchor moves.

Evidence

Window of tolerance is a core trauma-treatment concept; titrated exposure that matches intensity to current capacity is consistent with what controlled research on prolonged exposure and other evidence-based trauma treatments demonstrates. (clinical)

Window of tolerance is a theoretical construct; its application to yoga intensity specifically is clinical practice rather than a directly trialed parameter.

Common mistake

Pushing through discomfort with "no pain no gain" logic — which in a trauma context re-encodes the body as a site of forced endurance, the opposite of what the practice intends.
