What is overthinking and why can't we stop it? Learn about rumination and worry loops, what happens in the brain and exercises that break the thought spiral.
When you get into bed at night, does your mind replay something you said during the day, again and again? Do questions like "I wish I hadn't said that", "Was she angry with me?" and "What if tomorrow's meeting goes badly?" circle for hours, leaving you feeling completely unrested by morning? Overthinking has become one of the most talked-about psychological experiences on social media in recent years. Many people describe it as a personality trait: "I'm someone who thinks too much." Yet there is an important difference between thinking and going round and round inside the same thought. In this article we look at how this loop works, why it is so hard to get out of, how the brain is tricked in the process, and the methods you can apply step by step to break the thought spiral.
What Is Overthinking?
Overthinking is when a person thinks about a subject, event or possibility in a repetitive way that is hard to control, without reaching any solution or taking any action. In psychology, this experience is examined under two main headings:
- Rumination: Repetitive thinking about the past. It circles around questions such as "Why did this happen?", "Why me?" and "I wish I had acted differently." It is closely linked to depression.
- Worry: Repetitive thinking about the future. It circles around questions such as "What if this happens?" and "What if I can't do it?" It is closely linked to anxiety.
What both types have in common is this: the person believes that by thinking they will reach a conclusion, solve a problem or prepare themselves. But the thoughts lead not to a solution but to new questions and more distress.
The difference between healthy thinking and overthinking
Healthy problem solving focuses on a concrete problem, weighs up the options and ends with an action plan. For example, the question "How can I cope with the rent increase?" can turn into steps such as reviewing your budget, talking to the landlord or researching other options.
An uncontrolled thought loop, on the other hand, is abstract, has no end and does not turn into action. Questions like "Why does this always happen to me?" and "What if nothing ever gets better?" are not questions that can be answered; so the more the mind looks for an answer, the more new questions it produces.
A simple test you can ask yourself is: "After thinking about this, have I made a decision or identified a step, or do I just feel worse?"
What Are the Signs of Overthinking?
The signs below do not amount to a diagnosis on their own, but they can help you notice your thought loops:
- Reliving past conversations and events in your mind again and again
- Analysing other people's words and behaviour at length, wondering "what did they really mean?"
- Building negative scenarios that have not happened
- Getting stuck for a long time even on small decisions
- Writing and deleting a message many times before sending it
- Having difficulty falling asleep, the mind not "switching off"
- Constant fatigue, difficulty concentrating
- Being unable to focus on the present moment, your head being elsewhere even during a conversation
- Constantly asking others for reassurance

What Causes Overthinking? What Happens in the Brain?
The thinking loop that keeps the mind so busy has several important sources.
Beliefs about thinking: In psychology, our way of "thinking about thinking", known as metacognition, plays a key role in this loop. Many people, without realising it, hold beliefs such as: "If I worry, I'll be prepared for bad things", "If I think enough, I'll find the right answer", "If I stop thinking, I'll be being irresponsible." These positive beliefs start the loop. Then negative beliefs follow: "I can't control my thoughts", "Thinking this much is going to harm me." This increases anxiety and deepens the loop.
Intolerance of uncertainty: People who find uncertainty unbearable try to remove it by thinking. But certainty is not possible in many areas of life; so the mind enters an endless effort.
Perfectionism: High standards such as "I must make the right decision" and "I must not make mistakes" lead to weighing every option over and over. We examine this subject in detail in our article on perfectionism.
Early experiences: People who grew up in families where mistakes were harshly criticised, love was conditional or the environment was unpredictable may have learned constant thinking as a survival strategy for sensing dangers in advance.
The brain's default network: When we are not focused on a specific task, there is a network that becomes active in the brain and turns towards thoughts about ourselves, the past and the future. This network is important for self-understanding and planning; but when combined with anxiety or low mood, it can lay the ground for repetitive negative thoughts. That is why the mind falls into a spiral more easily in idle moments, for example in the shower, on the road or in bed.
Why can't we stop thinking by thinking?
Saying "I won't think about this" often brings that thought to mind more often. In a well-known experiment in psychology, when participants were asked not to think of a white bear, it was observed that the bear came to mind more often. This is why the way out of the loop is not to fight the thought, but to build a different relationship with it.
Overthinking in the Digital Age and in Today's Turkey
The amount of information feeding our minds today is incomparably greater than for previous generations. "Seen" marks in messaging apps, messages that get no reply and every interaction on social media create a new source of thought open to interpretation. The question "She saw my message but didn't reply, is she angry?" can turn a few seconds of information into hours of analysis.
AI chatbots have opened up a new space for thinking too. Some people ask these tools the same problem many times in different ways and find a new "but what if" in every answer. This can work like a digital equivalent of the old habit of constantly asking friends for reassurance.
What does overthinking cost us?
The cost of the loop is often paid quietly. The first is time: five minutes spent answering a message can turn into an hour spent thinking about how the reply will be received. The second is energy: being constantly mentally busy creates fatigue even if you do nothing physically. The third is the present moment: if your mind is elsewhere while playing with your child, having dinner with a friend or out walking, you miss the enjoyment of that moment. The fourth is action: although overthinking makes a person feel prepared, it often delays taking a step. Research shows that repetitive negative thinking can weaken problem-solving skills and prolong low mood. Seeing these costs can be a powerful source of motivation for getting out of the loop.
The high cost of living and economic uncertainty also increase worries about the future. Questions like "How will I make it to the end of the month?", "Will I be able to buy a home?" and "Will I be able to afford my child's education?" are real and important questions. But when these questions do not turn into concrete steps, they can enter an endless loop in the mind.
How Do You Stop Overthinking? Step-by-Step Methods
Overthinking is strengthened by habit and loosened by habit. The methods below aim not to destroy thoughts but to stop them from running you.
1. Notice and name the loop
The first step is to notice that you are inside the loop. Say to yourself, "I'm going round the same subject again." This awareness takes you one step out of the thought. Some people give these loops a name: "The 'what if' radio is playing again." This small touch of humour helps you put some distance between yourself and your thoughts.
2. Is it solvable or not?
Ask yourself this question about what you are thinking: "Is this a concrete problem I can do something about right now?" If yes, take five minutes to write the possible steps on paper and identify the smallest first step. If no, meaning the subject is in the past or completely out of your control, accept the thought and direct your attention to something else.
3. Set a worry time
Set aside a 15–20 minute "thinking time" during the day. Jot down the worries that come to mind during the day and say "I'll think about this at 7 pm." At the set time, look at your notes. Many people notice that by that time a significant part of the worries has lost its intensity. This technique teaches you to set a limit on thoughts instead of suppressing them. Take care not to place your worry time right before bed.
4. Move your attention to your body and surroundings
When the mind slips into the past or the future, use your senses to come back to the present. Feel your feet touching the floor, count five objects in the room, follow your breath going in and out through your nose. An activity that keeps your hands busy, for example cooking, knitting or gardening, can also help draw attention away from thoughts.
5. Put your thoughts on paper
Thoughts going round in the mind often look smaller and more manageable once written down. For five minutes, write down everything that passes through your mind, without correcting or judging it. Then look at what you have written and ask: "Which of these is fact, and which is prediction?"
6. Take a step back from the thought
Try expressing a thought not as "I'm definitely going to fail" but as "I am having the thought that I'm going to fail." This small change in language reminds you that the thought is an event your mind has produced, not a fact. You can imagine your thoughts as leaves floating down a river: without trying to stop or catch them, watch them come and go.
7. Reduce reassurance seeking
Asking friends, family, the internet or AI tools the same question again and again brings short-term relief but feeds the loop. When the urge to seek reassurance comes, try putting it off for a few hours.
Not every thought is an invitation; some you can greet at the door and see off without letting them in.
When Should You Seek Professional Support?
Support from a mental health professional can be useful in the following situations:
- If repetitive thoughts take up a large part of the day
- If your sleep, work, school or relationships are clearly affected
- If the thoughts occur together with intense anxiety, panic attacks or low mood
- If you have marked difficulty making decisions (you can look at our article on indecisiveness on this subject)
- If the thoughts are distressing, unwanted and repetitive, and you carry out particular rituals to relieve them
If you are experiencing hopelessness or thoughts of harming yourself, this is an emergency; call 112 (emergency services) without delay. A psychiatrist can assess whether the symptoms require medication. Psychotherapy support in the area of anxiety and panic can be continued face to face or online.
How Is Overthinking Approached in Therapy?
When working with overthinking in therapy, the aim is not to silence the person's thoughts but to help them build a more flexible relationship with them.
Cognitive Behavioural Therapy (CBT): The situations that trigger thought loops, automatic thoughts and their effect on emotions and behaviour are examined together. Thinking errors such as catastrophising, mind reading and "all or nothing" thinking are noticed. Problem-solving skills and behavioural experiments are used to test how far thoughts match reality.
Metacognitive approaches: In this work, the focus is on beliefs about thinking rather than on the content of thoughts. Beliefs such as "Worrying protects me" or "I can't control my thoughts" are questioned. Exercises that increase attentional flexibility and techniques such as postponing thoughts are practised.
Acceptance and commitment-based work: Taking distance from thoughts, returning to the present moment and taking action in line with values are the core components of this approach.
Schema-focused work: If beneath the repetitive thoughts there are early beliefs such as "If I make a mistake I'll be rejected" or "If I don't control everything it will be a disaster", the origins of these beliefs and their effects today are examined.
Frequently Asked Questions
Is overthinking an illness?
It is not a diagnosis on its own; it is a way of thinking that many people experience from time to time. However, it can be part of conditions such as generalised anxiety disorder, depression or obsessive compulsive disorder. A specialist assessment clarifies this distinction.
Why does overthinking get worse at night?
At night, external stimuli decrease and the mind is left alone with itself. Tiredness also lowers the capacity to regulate emotions. That is why thoughts you easily set aside during the day can look more intense and more important at night.
Is it possible to stop thinking completely?
It is not possible to stop thinking completely, and that should not be the aim. The aim is to notice your thoughts, to build distance from them and to be able to direct your attention where you want it. This skill grows stronger over time with regular practice.
Is meditation good for overthinking?
Mindfulness exercises can support taking distance from thoughts and developing attentional flexibility. At first it is normal for the mind to wander constantly; what matters is noticing that it has wandered and gently returning.
