How to Stop Overthinking Everything: 7 Steps That Help

To stop overthinking, give your worries a set time and place, turn "why" loops into concrete "what next" steps, write a specific to-do list before bed, get outside for a walk, practice mindfulness and protect your sleep. Each of these has been tested in studies of people who worry or ruminate (McGowan and Behar, 2013; Watkins and Moulds, 2005; Scullin and colleagues, 2018; Bratman and colleagues, 2015; Jain and colleagues, 2007). This guide explains what overthinking is, the signs to look for, 7 steps that help, how to stop overthinking at night, and where supplements fit.

Key Takeaways

Overthinking keeps you stuck: rumination makes negative thinking worse, gets in the way of problem solving and makes it harder to act (Nolen-Hoeksema and colleagues, 2008).
Give worry a time slot: a daily 30 minute worry period in a fixed time and place cut worry and sleep problems over 2 weeks in people who worry a lot (McGowan and Behar, 2013).
Write it down before bed: 5 minutes writing a specific to-do list helped people fall asleep faster than writing about what they had already done (Scullin and colleagues, 2018).
Move and get outside: a 90 minute walk in nature reduced rumination, while the same walk in a city did not (Bratman and colleagues, 2015).

What Is Overthinking?

Overthinking is getting stuck in repetitive thoughts that do not lead anywhere. Psychologists split it into two kinds: rumination, which replays the past ("why did I say that?"), and worry, which runs ahead to the future ("what if it goes wrong?"). Rumination is more than an annoying habit; research shows it deepens negative thinking, makes problem solving harder, gets in the way of taking action and can wear down the support you get from others (Nolen-Hoeksema and colleagues, 2008). Thinking hard about a problem is useful; overthinking is when the thinking keeps going after it has stopped producing anything new.

Overthinking Symptoms

Common signs that thinking has turned into overthinking include:

Replaying conversations or mistakes over and over
Running "what if" scenarios about things that have not happened
Asking "why" questions that never reach an answer
Struggling to make decisions, even small ones
Lying awake because your mind will not switch off; bedtime worry, including about unfinished tasks, is a major reason people struggle to fall asleep (Scullin and colleagues, 2018)
Feeling tense or drained after a day of thinking rather than doing

If you notice body signs too, such as tight muscles, headaches or an upset stomach, our guide to the physical symptoms of stress explains what is going on.

Why Do I Overthink Everything?

Overthinking usually grows out of stress and habit. When you feel under pressure, the mind tries to solve the problem by thinking about it, but abstract thinking about causes and meanings ("why is this happening to me?") tends to make problem solving worse, while concrete thinking about specific steps ("what can I do next?") makes it better (Watkins and Moulds, 2005). The more often you ruminate, the more automatic it becomes. Our guide to lowering cortisol naturally covers the daily habits that keep stress in check.

How to Stop Overthinking: 7 Research-Backed Steps

1. Schedule a worry period

Pick a 30 minute slot and a place each day for worrying. When a worry comes up at other times, note it and save it for that slot. In a randomized study of 53 people who worried a lot, 2 weeks of this kind of time and place limited worry reduced worry, negative feelings and sleep problems more than a comparison approach (McGowan and Behar, 2013).

2. Switch from "why" to "how"

When you catch yourself looping, ask a concrete question: what exactly happened, and what is one thing I can do next? In an experiment, concrete, specific thinking improved problem solving compared with abstract "why" thinking (Watkins and Moulds, 2005).

3. Write a specific to-do list before bed

Spend 5 minutes writing down what you need to do over the next few days. People who did this fell asleep faster than people who wrote about tasks they had already finished, and the more specific the list, the faster they fell asleep (Scullin and colleagues, 2018).

4. Take a walk in nature

A 90 minute walk in a natural setting reduced self-reported rumination and activity in a brain area linked to it, while a 90 minute walk in an urban setting did not (Bratman and colleagues, 2015). A park, a tree-lined street or a trail all count.

5. Practice mindfulness

In a randomized trial of 83 students, one month of mindfulness meditation reduced distracting and ruminative thoughts compared with no training; relaxation training also eased distress, but the drop in rumination was specific to mindfulness (Jain and colleagues, 2007). Our guide to mindfulness for focus walks through simple practices, and non-sleep deep rest is another guided way to settle the mind.

6. Use a positive distraction

Dozens of experiments show that a positive distraction, such as a hobby, a puzzle, music or time with a friend, can lift a low mood (Nolen-Hoeksema and colleagues, 2008). The goal is a break from the loop, not avoiding the problem forever; come back to it in your worry period.

7. Protect your sleep

Adults need 7 or more hours of sleep, ideally with the same bed and wake time every day (CDC). Our guide on how to fall asleep fast has more tips for nights when your mind is busy.

How to Stop Overthinking at Night

Night is when overthinking often feels loudest. Hold your worry period earlier in the evening, not in bed (McGowan and Behar, 2013). Before lights out, write a specific to-do list for the next few days (Scullin and colleagues, 2018), and turn off screens at least 30 minutes before bedtime (CDC). If you are still awake and looping, a slow breathing exercise from our guide on how to calm down fast can help you settle.

Can Supplements Help With Overthinking?

No supplement switches off overthinking, and the steps above come first. L-theanine, an amino acid found in tea, is the most studied option for everyday stress. In a 4 week trial of 30 healthy adults, 200 mg a day of oral L-theanine lowered stress-related symptom scores and improved sleep quality compared with placebo (Hidese and colleagues, 2019). Our guide to the best supplements for stress and mood compares the main options, and our L-theanine ingredient page covers how it works.

When to See a Doctor

See a doctor or mental health professional if overthinking lasts for weeks, gets in the way of work, relationships or sleep, or comes with constant worry, panic, low mood or loss of interest in things you used to enjoy. These can be signs of anxiety or depression, and a professional can help you sort out what is going on. If you have thoughts of harming yourself, call or text 988 in the US to reach the 988 Suicide and Crisis Lifeline, or call 911 in an emergency.

Frequently Asked Questions

How do I stop overthinking everything?

Set a daily worry period, turn "why" questions into concrete next steps, write things down, get outside and practice mindfulness (McGowan and Behar, 2013; Watkins and Moulds, 2005; Bratman and colleagues, 2015; Jain and colleagues, 2007).

What causes overthinking?

Mostly stress and habit; abstract "why" thinking keeps the loop going and makes problems harder to solve (Watkins and Moulds, 2005; Nolen-Hoeksema and colleagues, 2008).

Is overthinking a mental illness?

No, overthinking on its own is a common habit, but heavy, lasting rumination is linked to low mood, so talk to a professional if it does not ease (Nolen-Hoeksema and colleagues, 2008).

How do I stop overthinking at night?

Worry earlier in the evening, write a specific to-do list before bed and put screens away 30 minutes before bedtime (McGowan and Behar, 2013; Scullin and colleagues, 2018; CDC).

Does writing things down help with overthinking?

Yes; 5 minutes writing a specific to-do list at bedtime helped people fall asleep faster (Scullin and colleagues, 2018).

Does walking help with overthinking?

A 90 minute walk in nature reduced rumination, while a city walk did not (Bratman and colleagues, 2015).

Does L-theanine help with overthinking?

Research has looked at stress rather than overthinking itself: 200 mg a day of oral L-theanine lowered stress-related symptom scores in healthy adults (Hidese and colleagues, 2019); see our L-theanine dosage guide.

How long does it take to stop overthinking?

In one study, 2 weeks of a daily worry period was enough to reduce worry (McGowan and Behar, 2013), and one month of mindfulness reduced rumination (Jain and colleagues, 2007).
