Key takeaways

  • Answering the thought is the move everybody tries first and the one that keeps the conversation open. What works is changing the process rather than settling the content.
  • Worry postponement has been tested since 1983: self-described worriers given stimulus-control instructions reported significantly less worry than untreated controls.
  • Distraction is not avoidance. In a controlled comparison, people who were mildly depressed became measurably less depressed after eight minutes of distraction and more depressed after eight minutes of rumination.
  • Self-distancing, considering the situation from outside rather than inside it, is the difference between reflecting on a problem and reliving it.
  • Almost none of this works on the first attempt, because the loop is habitual and habits are interrupted by repetition rather than by insight.

The move nearly everybody tries first is to answer the thought. Settle the question, establish what really happened, work out what they meant, and then the thinking will stop.

It does not stop, because answering is participation. Every answer produces the next question, and an hour later you are further in with a slightly worse mood. What works instead is changing the process, and there are three approaches with actual evidence behind them.

Give worry an appointment instead of resisting it

Worry postponement is the oldest technique here and one of the best supported. In the original study, people who described themselves as worriers were given stimulus-control instructions, a specific time and place set aside for worrying, with the instruction to postpone worry to that slot when it arrived elsewhere. They reported significantly less worry than untreated controls. [borkovec-1983-stimulus-control]

The distinction that makes it work is between postponing and suppressing. You are not telling yourself the thought is wrong or refusing to have it, which tends to make it louder. You are saying: not now, at half past six.

How to run it:

  • Pick a fixed slot, 15 to 20 minutes, at the same time daily, not within two hours of bed.
  • When worry arrives outside the slot, note the topic in one line and return to what you were doing.
  • Turn up to the slot. This is the part people skip, and skipping it turns postponement into suppression, which fails.
  • Use the slot properly: read the list, and for each item write the next concrete action or the words “nothing to do today”.

Most people find that a third of the list has evaporated by the time the slot arrives, which is itself worth seeing.

Move attention deliberately when the mood is already low

Distraction has a bad reputation it does not entirely deserve. In a controlled comparison, mildly to moderately depressed participants spent eight minutes either focusing on their feelings and personal characteristics, or on descriptions of places and objects. The first group became significantly more depressed. The second group became significantly less depressed. [nolen-hoeksema-1993-distraction]

Eight minutes. That is the size of the intervention, and it is worth knowing because the reflex when a mood drops is to examine it, which is the condition that made people worse.

The distinction from avoidance is whether you come back. Distraction that gets you out of a spiral so you can address the problem is a tool. Distraction that becomes the plan is avoidance, and it has the opposite effect over time. In practice the difference is usually visible in the choice: something absorbing and effortful works, and scrolling generally does not.

Eight minutes of somewhere else

If the thinking is going round and the mood has already dropped, this is the interval the research used. Pick something absorbing enough to require attention: a task with your hands, a walk with something to look at, a conversation. Not your phone.

Coming back to the problem afterwards is part of it rather than a failure. The point was never to escape the problem, only to stop working on it from inside a worse mood.

Step outside the situation to look at it

The third approach changes your vantage point rather than your attention. Reviewing a difficult experience from inside it, as it happened to you, tends to reactivate the feeling and produce more of the same thinking. Reviewing it from a step back, as though watching from a distance, supports understanding instead. [kross-2011-self-distancing]

The practical version is smaller than the theory suggests. Ask why did that happen rather than why do I feel like this. Describe the situation as though to somebody who was not there. Some people find using their own name works, which sounds absurd and is doing something specific: it moves the grammar of the thought out of the first person.

What this does not do is make the situation acceptable. It makes it examinable, which is the step the loop never reaches.

Why none of it works the first time

Because the loop is a habit rather than a decision, and it is under way before you notice. The first fortnight of any of this consists mostly of realising twenty minutes late that you have been doing it again.

That is the practice, not a sign it is failing. The marker of progress is not silence, it is the interval between starting and noticing, and that interval shortens. Our guide to overthinking covers why the loop begins without a decision in the first place, and mindfulness for overthinking covers the noticing skill directly, since that is the one everything here depends on.

Which of the three fits your loop?

Tick anything true of the last week. This is a reflection prompt rather than a test, and it produces no diagnosis.

No screener on this site measures overthinking. If low mood or anxiety is part of it, the depression and anxiety screeners on that hub use PHQ-9 and GAD-7, the questionnaires most clinicians use, and they give you a number to bring to an appointment.

When to seek help

Speak to a doctor if repetitive thinking has been costing you sleep, work or relationships for more than a few weeks and none of the above has shifted it, or if it comes with low mood, loss of interest or persistent physical tension. Say that you have tried worry postponement and what happened, since that detail tells a clinician something a general description of stress does not.

Go sooner if you are drinking or using something to make the thinking stop, or if you have stopped making decisions rather than making them badly.

Go urgently if you have thoughts of harming yourself. Contact your local emergency services or a crisis helpline.

How MyFreud can help

Whether the loop tracks your mood or arrives regardless is the detail that decides which of these three to reach for, and it takes a fortnight of data to see. MyFreud gives you daily mood tracking that shows the pattern across weeks.

Frequently asked questions

How do I stop overthinking?

Change how you are thinking rather than what you are thinking about. Three approaches have research behind them: postponing worry to a scheduled slot instead of resisting it all day, deliberately shifting attention elsewhere when your mood is already low, and stepping back to view the situation from outside yourself. What does not work is trying to answer the thought, which is what nearly everybody does first.

Does worry postponement actually work?

It has held up since the original 1983 study, in which self-described worriers were given stimulus-control instructions, a set worry period at a set time and place, and reported significantly less daily worry than untreated controls. The mechanism is not suppression. You are not refusing the worry, you are deferring it to an appointment, which is why it works when resisting does not.

Is distraction just avoidance?

They look identical and behave differently. Avoidance means not doing something because the feeling is intolerable, and it makes the feeling grow. Distraction here means deliberately moving attention when your mood is already low and the thinking is going nowhere, which is a documented mood-repair move. The test is whether you go back: brief distraction followed by dealing with the problem is not avoidance, and permanent distraction is.

How long does it take to stop overthinking?

Longer than an insight and shorter than most people fear. Repetitive thinking is described in the research as habitual, so it starts automatically and does not respond to a single decision to stop. Expect weeks of catching it late and doing the practice anyway. Catching it earlier each time is the actual progress marker, not silence.

What if the thing I am overthinking is a real problem?

Then the question is whether the thinking is solving it. Overthinking a real problem is still overthinking, and the research finding that most surprises people is that it degrades problem-solving rather than improving it. The move is to convert the loop into one concrete next step, write that step down, and stop. If there is no next step available today, that is information rather than a reason to keep going.
