If your mind loops the same worries and “what‑ifs,” you’re not alone. Overthinking, often experienced as rumination (dwelling on the past) or worry (anticipating the future), is a common thought habit that can drain energy and increase stress. So, why does it happen, and , how can you loosen its grip?
The Science Behind Overthinking
To begin with, research shows overthinking is tied to repetitive negative thinking (RNT), a pattern linked to anxiety and depression. In fact, a 2023 meta-analysis found rumination and worry overlap but aren’t identical, rumination focuses on past problems, while worry anticipates future threats. Both patterns can keep us stuck in mental loops.

Why Your Brain Loves Loops
Moreover, neuroscience offers an explanation. A key player is the Default Mode Network (DMN), a set of brain regions active during self-reflection and mind-wandering. When DMN activity ramps up under stress, it can fuel rumination and worry. In other words, your brain’s natural tendency to drift inward can become a trap when combined with negative thinking.

Why Fighting Thoughts Backfires
At first glance, it seems logical to try to “stop thinking.” However, research shows that suppression often makes thoughts louder. This happens because pushing thoughts away increases mental effort and stress. Instead, a more effective approach is to change your relationship to thoughts, seeing them as mental events, not facts.

5 Science-Inspired Ways to Unhook from Overthinking
Now that we understand why overthinking happens, let’s look at practical steps you can take:
- Name the Thought
For example, label it: “Thanks, mind, story about failure.” This simple step creates distance. - Repeat It Out Loud
Next, say the thought slowly for 20–30 seconds. It starts to feel like just words, not truth. - Ground in the Present
Then, try the 3-3-3 rule: name 3 colors, feel 3 sensations, take 3 breaths. - Ask: Is This Helpful?
Instead of “Is this true?” ask, “Does this move me toward the life I want?” - Take a Tiny Step
Finally, choose one small action aligned with your values, send the email, take a walk, call a friend.

FAQs
Is overthinking caused by anxiety or depression?
Both. Worry aligns more with anxiety; rumination aligns more with depression.
Can mindfulness help?
Yes. Mindfulness reduces mind-wandering and helps you stay present.
What’s the fastest way to unhook from spiraling thoughts?
Pause, name the thought, and take one small action toward what matters.
