Ever had that weird, tiny rush of peace when you see sunlight hitting a puddle? Or maybe it's that specific smell of old books or the way your cat’s ears twitch when they’re dreaming. It’s not a "high." It’s not a life-changing epiphany. It’s just... nice.
That’s a glimmer.
The term is everywhere lately, especially on TikTok and Instagram, but it actually has real roots in clinical psychology. It’s basically the biological opposite of a trigger. While we’ve spent decades talking about what sets us off, we’re finally starting to talk about what brings us back.
Where the Hell Did This Word Come From?
Look, "glimmer" isn't just some Gen Z slang invented for aesthetic mood boards. It was coined back in 2018 by Deb Dana, a licensed clinical social worker. She’s a big deal in the world of Polyvagal Theory—a framework developed by Dr. Stephen Porges that explains how our nervous system reacts to perceived safety or danger.
Dana realized that while "triggers" move us into a state of fight-or-flight (the sympathetic nervous system) or total shutdown (dorsal vagal), we needed a name for the things that cue our body into a state of safety and connection. She called them glimmers.
They are micro-moments.
They happen in a flash. If you aren't looking, you’ll miss 'em. Honestly, most of us do miss them because our brains are evolutionarily hardwired to look for the tiger in the bushes, not the pretty flower next to the tiger.
It’s All About Your Vagus Nerve
Your nervous system is constantly scanning the environment. Scientists call this neuroception. It’s happening right now. You aren't thinking about it, but your brain is asking, Am I safe? Is this person a threat? Is that loud noise a car backfiring or something worse?
When you experience a glimmer, your ventral vagal nerve takes the wheel.
This is the "rest and digest" or "social engagement" system. When this part of your nervous system is active, your heart rate slows down, your breathing softens, and you feel—even if just for three seconds—that the world is okay. It’s the feeling of a warm cup of coffee against your palms on a Tuesday morning when you’re actually running late but for one second, the steam looks cool.
Why Glimmers Aren't Just "Toxic Positivity"
I know what you're thinking. This sounds a lot like "just think happy thoughts" or "gratitude journaling," which can feel really dismissive when you’re actually struggling with depression or trauma.
But it’s different.
Toxic positivity tries to overwrite your pain. It says, "Don't be sad! Look at the sun!" Glimmers acknowledge that the world is often heavy and exhausting, but they remind your nervous system that safety still exists. You can be in a dark place and still notice a glimmer. In fact, that’s when they matter most.

Glimmers don't fix your problems. They don't pay your rent. They don't cure chronic illness. They just give your nervous system a tiny break from the "alert" phase.
The Science of Noticing
Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections. If you spend all day looking for things that suck, your brain gets really, really good at finding things that suck. It builds a "suck highway" in your gray matter.
By intentionally looking for glimmers, you’re starting to pave a different road.
It takes effort.
In a 2022 interview, Deb Dana explained that we have to "contextualize" these moments. It’s not enough to just see a nice bird. You have to notice that you noticed it. That sounds meta, but that’s the "click" that tells your nervous system, Hey, we can relax for a second.
What Does a Glimmer Actually Look Like?
It’s personal. What works for me might do absolutely nothing for you. My glimmer might be the specific "clack" of mechanical keyboard keys. Yours might be the way your neighbor's dog always sits on the porch.
Common examples people report:
- The smell of rain on hot pavement (petrichor).
- A stranger nodding at you in a way that feels genuine.
- That one song that makes you feel like the main character.
- The feeling of clean sheets.
- A well-organized bookshelf.
- Seeing a "missing" poster for a pet that has "FOUND" written across it in Sharpie.
It’s about the mundane. If it’s too big, it’s a "milestone." Glimmers are small.
How to Find Your Own Glimmers Today
You don't need a meditation cushion or a $40 journal for this. You just need to pay attention. Start by trying to find one glimmer a day. Just one.
Don't force it. If you're having a terrible day, don't feel guilty if you can't find one. That just makes it another chore. Instead, just leave the door open for it. Maybe it’s the way the light hits your kitchen counter. Maybe it’s a funny text from a friend you haven't talked to in six months.
When you find one, take a breath. Feel it in your body. Does your chest loosen? Do your shoulders drop an inch? That’s the glimmer doing its job.
The Nuance of the Nervous System
We have to be careful not to turn "glimmers" into another productivity metric. You aren't "failing" at mental health if you don't see them. Trauma can make the world feel like a constant threat, and in those states, glimmers are hard to find because your brain is literally trying to save your life by staying hyper-vigilant.
If you're in a "dorsal" state—meaning you feel numb, frozen, or disconnected—glimmers might feel invisible. That’s okay. The goal isn't to be happy all the time. The goal is to build nervous system flexibility.
Flexibility means you can go into a stress state when you need to, but you can also find your way back out. Glimmers are the breadcrumbs that lead you back to the "safety" state.
Actionable Steps for the "Glimmer" Practice
If you want to actually use this concept to help your brain, try these specific, low-effort tactics.
First, name them. When you see something that makes you feel that tiny spark of "oh, that’s nice," say it out loud or in your head: "That’s a glimmer." Naming it engages the prefrontal cortex and helps your brain "save" the file.

Second, use your senses. We usually live in our heads, thinking about the past or the future. Glimmers live in the present. What can you feel, smell, or hear right now that doesn't feel like a threat?
Third, share them. If you’re with a partner or a friend, tell them. "Look at the color of those clouds." Not only does this reinforce the glimmer for you, but it acts as a co-regulation tool for the other person. You’re literally helping their nervous system feel safe, too.
Why This Matters in 2026
We live in a world designed to trigger us. Algorithms thrive on outrage because outrage keeps us clicking. Our phones are basically "trigger delivery devices."
In an environment that is constantly screaming for our attention and our cortisol, the act of noticing a glimmer is actually a tiny act of rebellion. It’s choosing to reclaim your nervous system for a few seconds.
It’s not world-changing, but it is life-changing.
Over time, these micro-moments accumulate. They create a reservoir of safety you can dip into when things get loud again. It won't make the hard stuff go away, but it might make the hard stuff a little easier to carry.
Next Steps for You:
- Audit your environment: Look around your room or office right now. Find three things that don't evoke any stress. A plant? A favorite pen? A photo? Those are your baseline glimmers.
- The "Glimmer Buddy" system: Text one person today and ask them what one small thing made them smile. Don't make it a deep conversation. Just a quick exchange of small joys.
- Physical check-in: The next time you see something beautiful or peaceful, notice where you feel it in your body. Is it a warmth in your stomach? A softening of your jaw? Memorize that physical feeling so you can recognize it more easily next time.
