How to Stop Overthinking: 9 Exercises for the Loop You Are Actually In

It is 2:14am and you are running the same forty seconds again. What you said in the meeting. The tone of the reply. The thing you should have said instead, which you have now rehearsed eleven times in a version of the conversation that already ended.

You do not need to be told that this is unhelpful. You know. Most advice on how to stop overthinking is a version of the instruction itself, which is like being told to stop hearing a sound — the instruction and the problem live in the same place.

What actually works is not a decision to stop. It is a different thing to do with your hands and your attention for the next four minutes, chosen to match the specific kind of loop you are in. There are two kinds, they need opposite treatments, and most advice fails because it gives you the wrong one.

This page has nine exercises, sorted by which loop you are actually in, plus the shutdown routine that stops the loop starting in the first place.

The two loops, and why the difference matters

Almost all overthinking is one of two things:

The Replay. Something already happened. You are going over it — the email you sent, the way you laughed too loudly, the thing your manager said that could have meant three things. The loop is about accuracy: you are trying to establish what really happened and what it meant.

The Rehearsal. Something has not happened yet. You are running scenarios — the conversation on Monday, the appointment, the decision you have not made. The loop is about control: you are trying to be ready for every version so that nothing catches you out.

They feel identical from the inside. Both are the same tight, circular, slightly urgent quality of attention. But they respond to completely opposite things.

A Replay stops when you write it down and close it. It is looking for a conclusion, so give it one — on paper, where it stays.

A Rehearsal stops when you make one small decision. It is looking for readiness, so give it the smallest concrete piece of readiness available, and it loses its reason to continue.

Do it the wrong way round and you make it worse. Journalling about Monday’s meeting at midnight is feeding a Rehearsal more material to work with. Deciding your “next action” about a conversation that happened last Tuesday is nonsense — there is no action, that is why it keeps going.

The test, and it takes four seconds: is the thing I am thinking about in the past or the future? That is it. If you cannot tell, it is a Replay wearing a Rehearsal’s clothes — you are replaying something and calling it planning.

If you want the underlying picture of why this becomes automatic, why overthinking is a habit, not a personality trait is the piece to read alongside this one.

Three exercises for the Replay

1. The Two-Column Page

Take a sheet of paper. Two columns. Left: what was actually said or done — only things a camera would have recorded. Right: what I have added — meaning, motive, tone, what they were probably thinking.

Write until both columns are empty of new material. Usually three lines on the left and fourteen on the right.

Why it works: the loop runs on the right-hand column and pretends it is the left. Once the two are physically separate on the page, the manufactured part stops passing as information. You are not arguing yourself out of anything, which is what fails. You are sorting.

What you do next: fold the page, put it somewhere specific — a drawer, the back of a notebook. Not the bin. The loop will come back and ask to check something, and being able to answer “it is written down, in the drawer” is what makes it let go.

2. The Witness Test

Ask one question, out loud if you can: would a stranger watching have noticed?

Not your friend, who knows you. Not the person involved, who has their own reasons. A stranger. Someone who wandered into the meeting halfway through.

The honest answer is nearly always no. The pause before you said the thing was half a second. The laugh was a normal laugh. The email read as an email.

Why it works: the Replay makes you the main character in someone else’s day. The Witness Test restores the actual scale, and scale is the thing the loop is worst at.

3. The Apology Audit

For the loop that is specifically about having done something wrong. Write the answer to three questions, in this order:

1. What exactly did I do? One sentence, no adjectives.
2. Who was affected, and how would they describe it?
3. What is the repair — a sentence, an action, or nothing?

Then do the repair, once, and stop. If the answer to three is “nothing”, that is a complete answer.

Why it works: guilt with no available action is what keeps a Replay running indefinitely. The audit either produces an action, which ends it, or proves there is not one, which also ends it — slower, but it ends it.

What you do next: if the repair is an apology, keep it to one sentence and do not explain. Explained apologies invite a second conversation, which starts the loop again.

Three exercises for the Rehearsal

4. The If-Then Line

You are running twelve versions of Monday. Stop and write exactly one line, in this shape:

If [the thing you are dreading] happens, I will [the specific thing you will do].

If she asks why the report is late, I will say the data came in Thursday and offer the Friday version.

One line. One scenario — the one you keep coming back to, not all twelve.

Why it works: a Rehearsal is a readiness-generating machine with no off switch, because nothing you think ever counts as ready enough. A written If-Then is the first thing that counts. The loop checks, finds an answer, and quiets down.

What you do next: when it starts again, do not write a second line. Reread the first. Rereading is the point.

5. The Decision Deadline

For the loop that is a decision you have not made. Give it a time and a size:

I will decide by Thursday 6pm. Until then I am not thinking about it. If I have not decided by Thursday, I take the option that is easiest to reverse.

Put the deadline in the calendar so it exists outside your head.

Why it works: most undecided decisions are not hard, they are unbounded — there is always more to consider, so considering never ends. A deadline converts “keep thinking” into “think on Thursday”, which is a thing you can actually stop doing today.

The fallback clause matters as much as the deadline. Deciding in advance what happens if you fail to decide removes the second loop, the one about whether you will manage to decide.

6. The Smallest Next Action

Write down the smallest physical thing that moves this forward. Not the plan. The next movement.

Not “sort out the insurance” — find the policy number. Not “have the conversation” — send the message asking when they are free. Not “get on top of work” — open the document.

Then do it now if it takes under two minutes, or put it at the top of tomorrow.

Why it works: the Rehearsal is trying to solve the whole thing at once, in your head, which is the one place it cannot be solved. One small physical action moves the problem out of your head and into the world, where it gets smaller.

For the version of this that is not one problem but forty small ones you are holding at once, the invisible mental load covers why the holding itself is the tiring part.

Three exercises for the middle of the night

At 2am you cannot do a two-column page, and you should not try. Nothing you write at 2am is any good and the light wakes you up properly. These three are built for the dark.

7. The Parking Page

Kept on the bedside table, in advance. When a thought arrives, write four or five words — not the thought, the label. “Dentist.” “Reply to Sam.” “The thing about the invoice.”

Why it works: the loop repeats because it does not trust you to remember. A label is enough of a promise. You are not processing anything, you are filing it, and filing takes eight seconds.

What you do next: actually read the page in the morning. Once. If you never read it, the loop learns the page is a lie and stops accepting it.

8. The Boring Task

Pick something dull, mildly effortful and entirely internal, and do it on repeat. Count backwards from 300 in threes. Name every street on your route to work. Go through the alphabet finding a country for each letter.

Not counting sheep — too easy, it leaves room. Not breathing exercises if they make you monitor your breathing, which for some people is worse. Something that needs just enough of your attention to leave none spare.

Why it works: you are not calming yourself down. You are occupying the exact channel the loop needs. It is crowding-out, not relaxation, and it works when relaxation does not.

If you want other options in the same family, 10 grounding techniques and the 54321 technique both cover more of them.

9. The Get Up Rule

If you have been awake and looping for what feels like more than twenty minutes: get up. Leave the bedroom. Sit somewhere else in low light and do something undemanding — not a screen — until you feel sleepy, then go back.

Why it works: lying in bed losing an argument with your own head teaches you that bed is where that happens. Getting up keeps the bed for sleeping. It feels like the opposite of resting and it is the single most reliable thing on this page.

What you do next: if this is happening most nights rather than occasionally, the sleep pattern is the thing to fix rather than the thoughts. How to reset your sleep schedule after late nights and evening mindfulness practices for better sleep are both about the surrounding routine rather than the 2am moment.

The Shutdown Method

The exercises above are for a loop already running. This is the routine that stops most of them starting — six minutes at the end of the working day, in the same order every time.

1. The sweep (two minutes). Write down everything unfinished. Not organised, not prioritised — just out. Email, home, the message you have not answered, the thing you remembered in the shower.

2. The three (one minute). Circle the three that matter tomorrow. Only three. The rest stay on the page.

3. The next action (one minute). For each of the three, write the first physical movement. Six words each is plenty.

4. The open loops (one minute). Anything waiting on someone else gets a line of its own: what it is, who has it, when you will chase. This list is the one that otherwise runs at 2am.

5. The sentence (thirty seconds). Out loud or in your head, the same words every day: that is the working day finished. Same words. The repetition is what makes it a signal rather than a thought.

6. Close the laptop and physically move. Leave the room, walk round the block, change your clothes. The body has to cross a line for the day to feel closed.

Done daily this takes six minutes and removes most of the material a Rehearsal runs on, because everything it wants to remind you about is already written down and dated.

What makes it fail: doing it on a screen, in the tool you also work in — you end up working. Do it on paper. And doing it “when I get a moment”, which is never. Same time, same place, or it does not survive the second week. Why most routines fail after 2 weeks is the honest version of that problem.

When it is a conversation you cannot stop replaying

Sometimes the loop is not really about thinking. It is about something you did not say, and the replaying is your head trying to finish a conversation that ended badly.

Three options, in order of how often they work:

Say the missing thing, briefly. Not a re-litigation — one sentence, sent flat.

I have been thinking about Thursday. I should have said at the time that the deadline was not workable. Can we look at it again this week?

Write it and do not send it. The letter you never send is not a trick to make you feel better; it is a way of producing the words, which is the part your head is actually stuck on. Once they exist, the loop usually stops.

Accept that the conversation is over and the version in your head is not the one that happened. Return to the Witness Test.

If the same conversation keeps recurring with the same person, the problem is not the replaying. It is that a limit has not been stated. How to Set Boundaries has the exact wording for the most common versions of it.

What does not work, and why it feels like it should

Thinking it through one more time. The loop’s own suggestion, every time. It has never once been the last time. Rehearsal is a habit that pays out in relief for about ninety seconds, which is exactly the schedule that makes habits stick.

Asking someone to reassure you. It works briefly and raises the price. Reassurance is a thing you can need more of, and the loop learns that discomfort ends when somebody else says it is fine, which makes it worse at ending on its own.

Looking it up. Searching for the thing you are worried about produces more material to be worried about. It is a Rehearsal with a search engine attached.

Trying to stop. Deciding not to think about something is a thought about the thing. Everything on this page replaces the loop with an activity, rather than trying to switch it off, and that is not a coincidence.

Doing it in bed. Anything requiring effort — the sweep, the two columns, the decision — must happen at a table, in daylight, with clothes on. Bed is for the Parking Page and the Boring Task, and nothing else.

How to stop overthinking in seven days

If you would rather start with a sequence than a toolkit:

Day 1. Do the Shutdown Method once, at the end of the day. Six minutes, on paper.

Day 2. Put the Parking Page and a pen beside the bed before you need them.

Day 3. Next time a loop starts, name it out loud — “Replay” or “Rehearsal” — and pick the matching exercise. Naming it is most of the work.

Day 4. Write one If-Then line for the thing you are most rehearsing this week.

Day 5. Notice one thing you have been researching rather than deciding. Give it a deadline and a fallback.

Day 6. Do the Shutdown Method even though nothing is urgent. The quiet days are what make it a routine rather than an emergency measure.

Day 7. Read the week’s Parking Pages in one go. Most of what woke you up will have resolved itself without you. That is the finding worth having.

Some people find the whole thing works better in a written form from the start — daily writing rituals for mental clarity and morning pages both cover that route, and there is a set of journaling prompts for when you are overwhelmed if you want the questions supplied.

Where to go next

Everything in the Overthinking section builds on this page. If the loops are mostly about work and how much of it there is, Burnout & Work Stress is the next section. If they arrive through a phone — the notification you keep checking, the message you keep rereading — start with Digital Detox. And if writing turns out to be the thing that works for you, Journal Prompts is a whole section of questions to write against.

One honest note to finish on. Everything here is a habit-level tool for ordinary looping — the meeting, the message, the decision, the 2am replay. If the thinking is constant rather than occasional, if it is stopping you eating or sleeping or working for weeks at a time, or if it has moved from uncomfortable to frightening, that is outside what a website can help with and it deserves a professional who can actually assess it, in person. There is a real difference between a habit and a condition, and the tools for the first are not a substitute for the second.
