Scheduling the Worry Window

Set a fixed daily 15–30 minute period for worry, and let yourself worry freely only during that time.

Why it works

Thought suppression ("don’t think about that") reliably increases the frequency and intrusiveness of suppressed thoughts — the "white bear" rebound effect. Worry postponement sidesteps this by replacing suppression with containment: the worry is not forbidden, only delayed. This preserves the sense of control (worry is acknowledged) while disrupting the pattern of all-day generalization. Over time, postponement also demonstrates that most worries diminish naturally if not immediately engaged — the feared consequence (the anxiety will build unbearably) does not materialize.

How to do it

1. Choose a specific daily worry window — 15–30 minutes, at a consistent time, not close to bedtime (e.g., 5:00–5:30 PM).
2. When worry arises outside the window, write it briefly on a list and explicitly postpone it: "I’ll worry about this at 5 PM."
3. At the scheduled time, review the list and worry freely about each item — no distraction, no suppression.
4. At the end of the window, close the list and return to other activity.
5. Notice, over days, how many postponed worries feel less urgent by the scheduled time.

Evidence

Worry postponement has RCT support within CBT for GAD. Borkovec et al. showed that stimulus control for worry reduced worry frequency and its interference with daily life. The white-bear/thought-suppression mechanism (Wegner) has extensive experimental support. (rct)

Most worry-postponement RCTs test it as part of a CBT package for GAD rather than as a completely isolated technique; evidence is strong but not purely standalone.

Common mistake

Setting the worry window too close to bedtime — ruminating at 10 PM increases arousal and sleep latency, exacerbating anxiety rather than containing it.
