Most of us spend time thinking about things that have already happened and trying to anticipate what might happen next. We replay conversations, reflect on decisions, prepare for difficult situations and think through possible outcomes. This ability to mentally move backwards and forwards in time is useful. Looking back can help us learn, understand and make sense of our experiences. Looking ahead can help us plan, prepare and solve problems.

Sometimes, however, thinking stops being useful. We may find ourselves going over the same event repeatedly without reaching a new understanding, or trying to mentally prepare for every possible thing that could go wrong. The thinking can feel important, even urgent, but leave us no clearer about what to do. This is often what people mean when they describe themselves as “overthinking”.

Psychologists commonly distinguish between two forms of repetitive thinking: rumination and worry. They overlap considerably, but one useful way of understanding the difference is to think of them as different forms of mental time travel. Rumination tends to pull us backwards into the past, while worry tends to take us forwards into the future.

What Is Rumination? When Thinking About the Past Stops Helping

Looking back is not inherently unhelpful. Reflection allows us to think about what happened, understand our reactions, learn from experience and decide whether there is anything we would like to do differently. After a difficult conversation, for example, we might recognise that we became defensive, think about why the conversation affected us and decide that we would like to approach the person differently next time. The thinking has helped us arrive somewhere.

Rumination tends to be different. We may repeatedly return to questions such as, “Why did I say that?”, “Why does this always happen to me?”, “What must they think of me?” or “What is wrong with me that I reacted like that?” The mind can revisit the same material many times without gaining much new information. Instead of moving towards understanding or action, we keep arriving back at the same place.

The distinction is therefore less about whether we are thinking about the past and more about what the thinking is doing. Reflection can help us understand, learn or decide. Rumination tends to become repetitive and difficult to disengage from, and can maintain distress.

A useful question is, “Is this thinking helping me understand something, make a decision or take useful action?”

What Is Worry? When Planning for the Future Becomes a Loop

Thinking about the future is just as necessary. Planning helps us prepare for likely difficulties, organise ourselves and decide how we might respond to something that is coming up. Worry can look very similar to planning because both involve anticipating what may happen next.

One useful way to distinguish the two is that problem-solving involves an active attempt to plan and prepare for a current or sufficiently likely eventuality, whereas worry can become a mental attempt to plan and prepare for all eventualities. The first process tends to lead towards decisions and action. The second can keep generating more possibilities to consider.

Imagine you receive a bill that you cannot currently afford. There is a real problem in front of you. You might look at your finances, contact the provider, ask about a payment plan or consider other options. The situation may still be stressful, but the thinking can lead somewhere. Now imagine the thought becomes, “What if I have another large bill next month? What if my income changes? What if something unexpected happens and I cannot cope?” There may be some useful financial planning that can be done, but eventually the mind can move beyond preparing for what is reasonably likely and begin trying to prepare for every conceivable outcome.

This is one reason worry can feel productive. It resembles problem-solving, but it may never reach an endpoint because there is always another possibility to consider.

Is the Problem Solvable?

When we are caught in overthinking, it can be helpful to ask whether the concern is actually solvable. This is not quite the same as asking whether it is current or future-based, because a current concern can be very real and still be outside our control.

A financial problem, an overdue task or a difficult conversation may be at least partly solvable. In those situations, thinking may be useful if it helps us clarify the problem, consider realistic options and take action. Other concerns are current and important but not personally solvable. Someone may be distressed by a war, a natural disaster, a global issue or the illness of somebody they care about. Those concerns are not imaginary simply because the individual cannot fix them.

There may still be things within our influence. We might offer practical support, donate, advocate, seek reliable information or make choices that reflect our values. At other times, there may be very little we can change. Continuing to mentally work on the situation can then increase distress without increasing our influence over what happens.

This distinction matters because different problems require different responses. A solvable problem may need action. An unsolvable problem may require acceptance, emotional processing, support or a shift in attention.

What Is the Thinking Trying to Achieve?

When someone feels caught in worry or rumination, an understandable response is to ask, “How do I stop overthinking?” Sometimes another useful question comes first: “What am I hoping this thinking will do?”

Worry and rumination often have a function. We may be trying to understand why something happened, prevent ourselves from making a mistake, make sure we are prepared, gain certainty, resolve guilt, anticipate a threat or prevent a painful experience from happening again. That does not necessarily mean the thinking is achieving what we want it to achieve.

This is where identifying the function of the thinking can be helpful. If there is a genuine problem that can be solved, structured problem-solving may be appropriate. If we are searching for complete certainty about something that cannot be known in advance, further analysis may simply produce another question. If we are repeatedly revisiting an event because there is an emotion we have not processed, continuing to analyse the event may keep us mentally engaged without helping us move through the feeling.

It can therefore be useful to ask both, “What am I trying to achieve by continuing to think about this?” and “Is this way of thinking actually helping me achieve it?”

Recognising When Thinking Has Become a Loop

Being able to notice the process of thinking itself is sometimes described as metacognitive awareness. Rather than being completely absorbed in each thought, we begin to recognise patterns in how our mind is operating. You might notice that you have replayed the same conversation several times, or that each answer to a worry immediately generates another “what if?” question. You may realise that you have been trying to reach certainty about something that cannot currently be known, or that you have already identified the practical steps available and are continuing to think beyond them.

That awareness can create a useful point of choice. It does not require us to decide that the thought is irrational or wrong. It simply allows us to notice that the thinking process may no longer be producing anything new. From there, we can decide whether the situation calls for reflection, problem-solving, action, emotional processing or a shift in attention.

Can Mindfulness Help With Overthinking?

Mindfulness can play a different role. Rather than analysing the thinking process, mindfulness involves deliberately reconnecting with what is happening in the here and now.

When worry takes us into the future or rumination pulls us into the past, we can practise returning attention to present-moment sensory and bodily experience. That might mean noticing the feeling of our feet against the floor, the movement of the breath, tension or warmth somewhere in the body, sounds in the room, the temperature of the air or what we can see around us. We may quietly label what we notice, such as “tightness in my chest”, “cool air on my skin”, “traffic outside” or “my shoulders are tense”.

This type of interoceptive and sensory attention gives us a concrete experience to return to when the mind has become caught elsewhere. It can also help us experience an emotion as something that is happening in the present, rather than immediately treating the feeling as evidence that there is another problem we need to think our way through.

Mindfulness does not determine whether a concern requires action. If there is a solvable problem, taking action may be appropriate. If there is no action available at the moment, mindfulness can help us stay in contact with the present while allowing uncertainty, discomfort or emotion to be there without automatically moving into further analysis.

Different Patterns Need Different Strategies

There is no single technique that is right for every instance of overthinking. Sometimes the most useful response is to sit down and properly solve a problem. Sometimes we need to reflect on an experience rather than push it away. Sometimes the work involves recognising that we are seeking certainty that is not available. At other times, we may need to make room for an emotion, reduce repeated checking or reassurance-seeking, or practise bringing attention back to what is happening around us.

This is also why generic advice to “stop worrying” or “just distract yourself” is often not particularly useful. If we understand what the worry or rumination is trying to achieve, we can choose a response that is better matched to the situation.

Our minds naturally travel through time. We need the past to learn and the future to prepare. We also need the ability to return to the present when further thinking is no longer helping. The aim is not to stop reflecting or planning. It is to become more flexible in recognising when thinking is helping us understand, decide or act, and when it has become a loop that is no longer taking us anywhere new.

When Overthinking Becomes Difficult to Manage

If worry or rumination is taking up a significant amount of your day, interfering with sleep, affecting your mood or making it difficult to focus on what is happening around you, working with a psychologist can help you understand the pattern and identify strategies that fit what is maintaining it.

At The Victorian Psychology Clinic, our psychologists work with people experiencing anxiety, persistent worry, rumination and other patterns of repetitive thinking. Therapy can help you better understand what your mind is trying to achieve, identify when thinking is useful and develop more flexible ways of responding when it stops being so.
