Use the window actively, then stop

During worry time, deliberately work through the parked worries — then close the window on schedule.

Why it works

The window only works if it is honored on both ends: you actually attend to the worries (so deferral isn’t avoidance) and you stop when time is up (so worry stays contained). Engaging on purpose, then ending on schedule, trains worry to live inside its boundaries rather than expand.

How to do it

1. At worry time, review your noted worries deliberately, one by one.
2. Sort each into "solvable now" (act or plan) versus "not solvable" (practice letting it be).
3. When the timer ends, stop — even mid-worry — and move on to the next part of your day.

Evidence

Actively using and then bounding the worry period is integral to how the stimulus-control worry technique is taught in CBT. The original Borkovec stimulus-control protocol paired deferral with a bounded, deliberately used worry period, so honoring both ends of the window is part of the tested method rather than an embellishment. (clinical)

Honoring the time boundary is part of the mechanism; letting the window stretch indefinitely undoes the containment that makes it work.

Common mistake

Letting the window run long whenever worries feel pressing, which dissolves the boundary and lets worry reclaim the whole day.
