How to stop overthinking negative thoughts?

To stop overthinking negative thoughts, the most useful step is to recognise when you have entered the loop (known as rumination), stop trying to win the argument with the thought, and redirect your attention: move to a small, concrete action if there is something you can do, or to an activity that gets you out of your head if there is not. It is not about emptying your mind, which is unrealistic, but about changing what you do with the thought when it appears. If the loop is very frequent or overwhelming, talking to a mental health professional is a reasonable option.

What is rumination and how does it differ from thinking through a problem?

Rumination means going over the same thoughts or worries again and again without reaching a conclusion. The American Psychological Association (APA) describes it as repetitive, excessive thinking that interferes with other mental activity.

The difference from reflecting lies in the outcome. When you think a problem through in order to solve it, you move towards a decision or a first step. When you ruminate, you come back to the same point again and again, usually focused on what went wrong, on "why is this happening to me" or on what might happen, and you end up with more discomfort and the feeling of having made no progress.

Why do we get stuck in the loop?

Rumination often feels useful: it seems that if you think about it enough, you will find the solution or avoid repeating a mistake. In practice, the thought feeds itself and finds more room when there is tiredness, sustained stress, little sleep or high self-demand. Some studies also point to a possible link between low self-esteem and the tendency to ruminate, although it is a relationship that is still being studied.

Rumination often appears alongside anxiety and low mood, and it can intensify both, as well as affect sleep. That is why it is worth taking seriously, without dramatising it.

What can I do in the moment to get out of the loop?

These tools help break the cycle once it has started:

• Name it: telling yourself "I am ruminating" already creates some distance between you and the thought.
• Change activity: move around, exercise, get on with a household task, call someone or watch a film that absorbs you.
• Change place: going outside or to somewhere you have felt good breaks the inertia.
• Breathe slowly: a few minutes of deep breathing, paying attention only to the air going in and out, helps calm the pace of your mind.
• Check the thought: ask yourself whether it is really accurate, and whether you have been through something similar before and how it ended.

Distraction relieves the moment, but it rarely resolves the source, so it is worth combining it with the strategies in the next section.

How can I turn the thought into a plan?

When the loop revolves around a real problem, the key step is to get it out of your head and give it a shape:

• Write it down: describe the problem on paper in your own words.
• Break it down: split it into small parts instead of thinking of it as one huge block.
• Separate what depends on you from what does not: act on the first and, with the second, practise letting go.
• Choose a single concrete step: something small you can do today or in the coming days.
• Adjust your expectations: if the goal is unrealistic, swap it for an achievable one.

How can I stop the loop from coming back again and again?

• Spot your triggers: note where you were, at what time, with whom and what had happened just before it started.
• Look after the basics: getting enough sleep, moving regularly and resting gives the loop less room.
• Talk to someone who brings perspective: better a person who helps you see the whole picture than one who joins in going round in circles with you.
• Be kind to yourself: forgive your mistakes and acknowledge what you do well; harsh self-criticism feeds the loop.

When is it a good idea to seek professional help?

If the loop takes up a large part of your day, affects your sleep, your work or your relationships, or comes with a great deal of anxiety or very low mood, it is advisable to talk to a mental health professional. Cognitive behavioural therapy is one of the options used to work on rumination, and a professional can assess whether there is another condition behind it that deserves attention.

Frequently asked questions

Are rumination and anxiety the same thing?
No. Anxiety is a state of alertness and worry; rumination is a repetitive way of thinking. They can appear together and feed each other, so if both are intense or persistent, it is advisable to consult a professional.

Is thinking a lot always a bad thing?
No. Thinking in order to decide or plan is useful. The problem appears when the thinking repeats without getting anywhere and leaves you feeling worse than when you started.

Is distracting myself a way of avoiding the problem?
It can be a valid relief in the moment, but if the problem is real it is worth combining it with a concrete plan; otherwise, the thought tends to come back.

Does writing down what I am thinking help?
Putting the problem in writing and breaking it into parts helps many people get it out of their head and see which steps are possible. It does not need to be well written: it just needs to be yours.
