Have you ever caught yourself happily staring out the window, lost in thought about the past, or fantasizing about the future? Congratulations! You’ve been hanging out with your Default Mode Network (DMN). This incredible brain network works behind the scenes when you’re not actively focusing on the world around you. It might sound like a slacker’s paradise, but the DMN is actually one of the most important and productive parts of your brain.
Never even heard of it, you say? Well, you’re not alone. The DMN is one of your brain’s most unsung, undervalued, and downright unknown heroes, so let’s take a stroll through your brain’s favorite “chill zone” and explore why it’s important, how to get in touch with it, and how to make the most of its superpowers.
What is the Default Mode Network (DMN), anyway?
Think of the DMN as your brain’s “resting state.” When you’re not laser-focused on a task—say, when you’re daydreaming, reflecting, or just letting your mind wander… Pow! Your DMN lights up like a Christmas tree.
The DMN is a team of brain regions, including (but definitely not limited to) the medial prefrontal cortex, posterior cingulate cortex, lateral temporal cortex, and hippocampus (sorry for totally geeking out on you) that work together to help you:
- Reflect on yourself: “Am I doing okay? Am I happy? What’s my purpose in life?”
- Recall memories: “That time I embarrassed myself at karaoke? Epic fail.”
- Plan for the future: “Next year, I’m finally going to see Niagara Falls.”
- Understand others: “Why was my coworker so unhappy today?”
In short, the DMN is where your brain goes to ponder, reflect, and imagine.
Why is the DMN important?
The DMN isn’t just for daydreaming—it plays a critical role in mental health, creativity, and problem-solving.
- Self-awareness and growth:
Without the DMN, you’d struggle to reflect on your life, your goals, and your values. It’s the ultimate personal therapist, helping you sort through who you are and what you want. - Creativity and innovation:
Ever had a brilliant idea hit you while you were in the shower, taking a walk, or – my personal fave – handwashing dishes? That’s your DMN connecting the dots. When your brain isn’t bogged down with tasks, it gets creative. - Understanding others:
The DMN helps you empathize by imagining what others are thinking or feeling. It’s the MVP of social interactions. - Mental health:
A well-regulated DMN is linked to reduced stress and anxiety. On the flip side, an overactive DMN can lead to rumination (those endless “what ifs” and “should haves”), which is linked to depression.
How to get in touch with your DMN
In today’s go-go-go culture, your DMN might be a seriously underutilized tool for personal growth, as well as for understanding the world around you. Here’s how to reconnect:
- Take breaks:
Stop trying to be productive every second of the day. Take short mental breaks, even if it’s just staring out the window or closing your eyes for a moment. - Go for a walk:
Walking, especially in nature, activates the DMN. Ludwig van Beethoven, Albert Einstein, Karen Blixen, Friedrich Nietzsche… it’s no coincidence that some of history’s greatest thinkers swore by their daily strolls. - Meditate:
Mindfulness might seem like the opposite of daydreaming, but meditation strengthens the DMN’s ability to regulate itself. A calm DMN is a productive DMN. - Unplug:
Constant scrolling on your phone keeps your brain in “task mode.” Put down your devices and let your thoughts wander freely. - Get bored:
Yes, you read that right. Boredom creates the perfect conditions for the DMN to start working its magic. (I always remind myself of this whenever I’m stuck in a boring meeting…at least my DMN is having fun!)
How to develop and use your DMN productively
Once you’ve made friends with your DMN, here’s how to take it to the next level:
- Practice reflection:
Set aside time to journal about your day, your goals, or how you’re feeling. This strengthens your self-awareness and makes the DMN more effective. (Confession: even though I recommend journaling, I’m not very good at it. I’m inconsistent with my entries, and if I’m honest with myself, I don’t really enjoy doing it. I’ve discovered that I prefer simply thinking about my life, rather than writing about it. Hence, my next suggestion…) - Schedule thinking time:
Block out “mind-wandering” time in your calendar. Seriously. Give yourself permission to do nothing but think. My scheduled thinking time is often my favorite part of the day! - Engage in creative activities:
Activities like painting, writing, and playing (or listening to) music can prompt your DMN to flex its creative muscles. (Personal aside: since I already spend so much time writing professionally, I go for music. When I hear beautiful music, I can sense my DMN kicking into high gear. Give it a try!) - Set an intention before you zone out:
Before you take a walk or stare out the window, think about a problem you’d like to solve. Let your DMN reflect on it—you might be surprised at the insights it delivers. - Be mindful of overactivity:
While the DMN is a wonderful resource, it can become a nuisance if you let it spiral into negative thoughts. If this happens, gently redirect your focus to something positive or grounding.

Final thoughts: Your DMN is your superpower!
The Default Mode Network isn’t just your brain’s idle setting—it’s a powerhouse for creativity, self-awareness, and empathy. By giving it the time and space it needs, you’ll not only improve your mental health but also unlock your full potential.
So, the next time someone catches you staring off into space, just tell them, “Shhhh…my DMN and I are very busy right now.” You might be daydreaming, but your brain is hard at work—and that’s something worth celebrating.
Now, go forth and daydream! Your DMN is standing by, ready to welcome you.
