Move and use rhythm to shift state

Walking, swaying, drumming, dancing — rhythmic, whole-body movement to discharge and reset arousal.

Why it works

Movement changes the bodily inputs the brain uses to construct emotion, and rhythmic, repetitive movement in particular tends to be organizing and soothing for an activated system. Physical activity also shifts arousal directly and, over time, reduces baseline anxiety and depressive symptoms. The book’s emphasis on yoga, movement, and rhythm sits on this base.

How to do it

1. When keyed up or stuck, choose movement over sitting with the feeling alone.
2. Favor rhythmic, repetitive forms: a brisk walk, swaying, gentle bouncing, dancing, drumming.
3. Match intensity to your state — gentle when collapsed, more vigorous when agitated.
4. Notice the body afterward rather than rating whether you "feel fixed."

Evidence

Exercise reliably reduces anxiety and depressive symptoms in meta-analyses. Yoga specifically has shown promise for PTSD symptoms in small trials, though the evidence base is still limited. (rct)

General exercise benefits are robust; the trauma-specific yoga trials are small and preliminary. Treat movement as a strong general regulation tool, not a proven standalone trauma treatment.

Common mistake

Waiting to feel motivated before moving. From a low or shut-down state, motion usually has to come first and motivation follows — and forcing high intensity from collapse can spike anxiety instead.
