What Is Overthinking? How To Stop Overthinking The Past?

How To Stop Overthinking

The first thing to note is that overthinking is not the same as worrying, as science tells us. Overthinking is analyzing the same thought over and over. And usually, that thought is about something that happened in your past, but you could do nothing to fix it.

It is a destructive habit because the overthinker’s brain can not channelize those thoughts into actions or results. When it goes on for long, it becomes a mental health risk because these unending circles of thoughts can make one stressed and anxious. And in time, the overthinking person can even go into depression.

So, it is something one should not ignore, right? But what is the solution if one is a habitual overthinker? Read on to find out how to get over this harmful habit of thinking too much of your past.

What Is Overthinking

Overthinking is endlessly pondering over a negative event from the past life. The overthinker does not have many thoughts, but keeps running and analyzing in mind the same one incident repeatedly without reaching a solution or end.

The psychologists call it rumination, and justifiably so. The process is like what animals do — chewing cud for hours.

Rumination in animals is a way of digesting food found in most hoofed mammals, as cattle, camels, and giraffes. These animals bring up the food into their mouths from one of their four stomachs and then chew on it for hours before swallowing it back again.

The overthinkers do the same — pull up their disturbing thoughts and keep on chewing them with their mental teeth.

An overthinking mind dwells over an event that already happened and makes catastrophic predictions from it. Such a mind tends to view a mistake or a gaffe from a pessimistic and worst possible perspective.

Overthinking vs Worrying

Overthinking and worrying often work together, and make each other worse. Both overthinking and worrying involve excessive thinking of negative thoughts.

What makes overthinking different from worrying is this: the “worriers” make a fuss about the present or the future, while the “ruminators” go over stuff already in the past. An example each to differentiate between them:

  • Overthinking: Why did I not walk out that day?
  • Worrying: Can I even finish this by tomorrow?

Worry typically involves anxiety over negative outcomes in the future. It’s mostly about these two “what if” questions:

  1. What if the wrong thing happens
  2. What if the right thing doesn’t happen

Some amount of worrying is a normal phenomenon in our everyday lives. But too much worrying can lead to generalized anxiety disorder (GAD). Psychologists suggest worry often starts with and is maintained by having “thoughts about thoughts.”

What Causes Overthinking

Why do I overthink? Why people overthink? What does my overthinking signal?

Overthinking can be an early symptom of as well as a risk factor for generalized anxiety disorder (GAD) or major depression. If it goes on for long to affect one’s normal daily functions or change their behavior drastically, they should seek the help of mental health professionals.

As researched by psychologists and shown strongly, two of the most common origin-causes of overthinking is:

  1. Passive behavior learned from over-controlling parents
  2. Stressful, traumatic, and negative events from the past life

1. Passive Behavior Learned From Parents

Children who learn passive behavior from their parents often go on to develop a habit of overthinking.

One study found children between 5 to 7 years of age who had mothers telling them what to do instead of pushing them to try their own methods to solve problems were more helpless and passive when facing frustrating situations. It can then lead them into overthinking.

In another study, college students who reported their parents were overcontrolling showed higher levels of rumination.

2. Stressful & Traumatic Events From Past

Stressful events can trigger or worsen overthinking. In one study, many of the people who went through stressful situations like divorce and serious illnesses went on to develop overthinking. Moreover, one year later, they had a higher tendency to get depression and anxiety.

More research (as this and this) confirm stressful life events can indeed trigger overthinking and are linked with higher depression levels in later life, as early as 6 months.

10 Harmful Health Effects of Overthinking

If you overthink habitually, it can wreck your body and mind in many ways. The first thing to note is that overthinkers sleep badly, do not exercise regularly, eat erratically – and all of these harm their brain.

Rumination can seriously damage your brain and body health; take a look at these 10 effects below:

  1. Anxiety: They are always anxious because they are unable to reach any final point where their thoughts can stop, and then they can take action. More so, because they can not help themselves out of it.
  2. Depression: Rumination worsens depression and promotes negative thinking. Overthinkers tend to focus more on the negative memories of their past. They explain their present situations in pessimistic tones. They also express hopelessness about their future. Women are more prone to rumination, hence more likely to go into depression.
  3. Fear: They may reach a point where they start to dread meeting anyone, for these people might say things that might overload them with more negative thoughts. It can grow into severe cases of social phobia and agoraphobia.
  4. Stress: Distress, or the stress of the debilitating kind, is a close companion of overthinkers. While rumination causes stress, heightened stress causes further overthinking.
  5. Fatigue: Like any hamster running non-stop on its wheel, their racing minds stay drained of energy. Soon, this effect shows up in their bodies too. Their stressed bodies produce more cortisol, the stress hormone, which can then lead to burnout.
  6. Indecision: The overthinkers find it hard to find great or even good-enough solutions to their problems. Even when they conceive a potentially useful solution, they are not confident it would actually work. Moreover, they hardly have any intention or motivation to act on that solution. Overthinking is often referred to by another illustrative phrase: analysis paralysis.
  7. Substance abuse: Alcohol is a favored substance of abuse among overthinkers, studies have found. Overthinkers often indulge in binge-drinking. They also tend to smoke more and abuse prescription and non-prescription drugs.
  8. Loneliness: They are likely to stay in isolation and suffer loneliness, as they shun most social interactions. Also, they are quite good at repelling others with their pesky habit of harping about how bad they feel all the time.
  9. Sleeplessness: They find it extremely hard to shut out their thought loops and go to sleep. Overthinking keeps their mind and body in a state of arousal, not calmness, so they can not sleep. They fall asleep only when their brains are too tired to take another minute of wakefulness.
  10. Suicide risk: They are harshly self-critical and tend to have low willpower. These, together with social phobia and social isolation, increase the risk of suicide attempts. More so, as they do not seem to seek professional help, even when they are abusing drugs. Rumination can also cause revenge-seeking, and suicide could be the result.

The thoughts in an overthinking mind are in themselves damaging as they can not “avoid” thinking about them, and this makes them suffer helplessly. Once the intrusive thoughts start, there is seemingly no stopping them.

Susan Nolen-Hoeksema, the late founding editor of Annual Review of Clinical Psychology, a pioneering researcher in the field of rumination, author of Women Who Think Too Much and Eating, Drinking, Overthinking, wrote this of ruminators:

People become tired, even annoyed, with overthinkers for continuing to talk about their loss. They may simply withdraw, or if they can’t withdraw, they may eventually blow up at the overthinker, expressing anger and frustration rather than sympathy and concern.

— Susan Nolen-Hoeksema, “Mother of Rumination”

How To Stop Overthinking The Past: 4 Most Helpful Strategies

Everyone overthinks some times. The problems arise for those who find it difficult to stop the thoughts. It is easy to slip into a circular pattern of thinking and go on to severe stress and anxiety from there. The root of the solution lies in disrupting the cycle at the earliest.

So, how to break the cycle and stop overthinking events from your past?

To help you with overthinking, we have lined up four of the most effective strategies. You could adopt one or all of these proven approaches to curb and even end your overthinking cycle.

Here is how to stop the habit of overthinking the past:

1. Exercising Distraction

The first step here is awareness. Once you’re aware you are into the overthink mode and are replaying a past event over and over without reaching a decision, you can start this action:

Distract yourself.

Distraction means purposefully steering your attention to pleasant or neutral things, away from your negative thoughts. In plain words, to distract yourself means forcing your mind to think of something else, especially something pleasant.

In a study, Susan Nolen-Hoeksema and Jannay Morrow asked depressed students to focus their minds on geographical locations and objects, like “the size of the GoldenGate bridge” and “the shape of the continent of Africa,” for 8 minutes. After the exercise, the participants became noticeably less depressed as compared to another set of depressed students who were asked to focus on their emotions or symptoms.

The authors concluded, “naturally depressed subjects who engaged in a benign, distracting task showed significant relief from their depressed moods, to a level equal to that of the nondepressed subjects.”

A simple way you could distract yourself is by physically getting up from the place you’re in at that time and leaving. You could also distract yourself mentally by starting something that engages your mind — as listening to some soothing music or an upbeat song.

2. Practicing Mindfulness

Mindfulness practice is known to stop overthinking. Mindfulness does not attempt to suppress or cut down the disturbing thoughts. Instead, it trains the mind to accept the thoughts that arise without judging them or holding on to them and letting them go.

The overthinker in a mindful state does not try to control, change, or reduce the thoughts. It is this letting go of the meddlesome thoughts that paradoxically reduce their frequency in the long run.

In a study of 11 studies, Clinical psychologist Lilisbeth Perestelo-Perez, Ph.D., MPsych, and others found Mindfulness-Based Cognitive Therapy (MBCT) can reduce overthinking significantly. The mindfulness methods were equally effective in controlling rumination as medication and CBT. They also found the positive effects of mindfulness were there even a month after the end of therapy.

3. Engaging In Problem-Solving

Overthinking reduces the motivation to solve problems, as research shows. On the other hand, studies on depressive people staying stable after engaging in problem-solving suggest the same can hold good for rumination.

So, challenge yourself to look away from your loop of thoughts, and put yourself up for finding solutions to the problems playing in your mind. Challenge yourself to find ways to solve the issue at hand.

Susan Nolen-Hoeksema suggested problem-solving may prove to be more effective after first lifting your mood with distraction. So, you could throw in a distracting challenge for yourself — funny videos, Sudoku, yoga, juggling, or anything else you love to be distracted with — first. Then, you can focus your attention directly on finding a clear-cut solution to the present problem.

4. Employing The Thought-Box

The thought-box process is a highly helpful way to reduce overthinking.

Set up sometime in the day, say 20 or 30 minutes when you would allow yourself time to overthink. Set up an alarm on your phone for the end of this interval. During this time, begin by telling yourself you have absolute freedom to ruminate until the alarm-bell rings. Then let your mind do all kinds of overthinking. There are no limits and no control over your thinking process.

A small addition, however: You will sit with a writing pad and pen, and note down a few thoughts from those moving through your mind. Don’t stress it over that you have to put down each thought. Instead, be easy on yourself, and jot down just one or two streams of thoughts. It will be fine.

Call this your Thought Box.

How does this help?

First, whenever you feel you’re slipping into your habit of overthinking during the day, remind yourself you have fixed up a time for it in your Thought Box, and stop overthinking right there.

Second, by writing down a few thoughts, you force your mind to recognize that you have already given your attention to a particular worry, and now it is no good repeating it over in your mind since it’s already noted down on a paper.

Did Einstein Overthink

The short answer: Probably yes, probably no.

What scientific thinkers as Albert Einstein, Stephen Hawking, and Marie Curie did more of was deliberation.

Deliberation is thinking deeply about something over a long time to reach a careful, conscious decision. In doing so, deliberate thinkers often collaborated with others to troubleshoot and expand their input-to-output journey.

The keyword there is output. The thinkers from any field — science, philosophy, politics, business — always think to reach a decision or conclusion.

There's a difference between overthink and deep-think. The former doesn't let you reach any decision or take any action. Click To Tweet

In contrast, the overthinkers almost always do all the thinking on their own without reaching out for any collaboration. More importantly, as opposed to thinkers, they do not ever produce any output or action.

Final Words

Overthinking is one of the most vulnerable factors in your personality that puts you at a high risk of depression, often as soon as within a year of occurrence of a negative life event. It has also been linked to anxiety.

So, stay watchful and take note early if you’ve begun to overthink. Use the four methods above to arrest the irksome habit before it lets in other disruptive mental disorders.

However, if you find it hard to get over it by yourself, please do seek expert psychological help.
