While you’ve probably heard about triggers, or those moments that generate feelings of anxiety and stress, you might be less familiar with glimmers. A glimmer is the exact opposite of a trigger—it is some kind of cue, either internal or external, that brings one back to a sense of joy, safety, or comfort.
A glimmer can be anything from catching a view of the skyline of your favorite city to seeing a picture of your pet. These are the things that help you feel OK. It might be the sun filtering through the branches outside your window or your favorite song playing on the radio. These glimmers are personal and can help shift you into a more relaxed state.
In our overstimulated worlds, glimmers can be the answer to regulating our overwhelmed nervous systems.
Origins of the Concept of Glimmers
The concept of glimmers is part of Polyvagal theory. Coined by behavioral neuroscientist Stephen Porges and introduced in 1995, the theory describes how our autonomic nervous system (which controls involuntary actions like breathing) is searching for and reading cues to determine if they are dangerous.
This process is called neuroception, and the vagus nerve, which regulates organ functions, is responsible for it.
The term glimmer, however, was introduced in 2018 in the book The Polyvagal Theory in Therapy: Engaging the Rhythm of Regulation by licensed clinical social worker Deb Dana. It was popularized by a viral TikTok video in February 2022 by psychologist Dr. Justine Grosso, in a video that has nearly 100,000 likes.
Some Common Glimmers
If you’re still having trouble identifying what your own glimmers are, here are some common ones:
- Feeling the warmth of the sun
- Sensing the cool, salty ocean air
- The smell of cut grass
- Seeing a rainbow
- Sunlight sparkling on water
- Smelling lavender or some other relaxing scent
- Petting a dog or cat
- Being in nature
- A stranger smiling at you in public
- The perfect cup of coffee
Understanding Triggers and Glimmers
Triggers and glimmers might seem like they are exact opposites, but it’s more like they are two sides of the same coin. Both act as cues that lead your nervous system to react to the world around you.
Triggers activate feelings of stress and danger, causing your body’s fight or flight mode to kick in to ready you to deal with the threat. Glimmers, on the other hand, signal safety and connection and help you feel more at ease in the world.
Let’s take a look at what causes a trigger and what leads to a glimmer.
When You’re Triggered
When the brain is triggered, it associates past traumatic events as if they’re happening right now, leading the brain and body to be on high alert. Symptoms like rapid heartbeat might occur within the body as the fight-or-flight response occurs.
This response helps the body prepare for physical danger. That’s helpful when a tiger is chasing you, but much less helpful when you’re being chased by your own memories.
When you’re in that state, your sympathetic nervous system, which regulates the body’s response to a stressful situation, is activated, increasing the heart rate, blood pressure, and pumping extra adrenaline into your body to prepare you for danger. If this system is activated too often or for too long, it can lead to health problems like chronic high blood pressure and insomnia.
Polyvagal theory often utilizes a “ladder” analogy. At the bottom of the ladder is the dorsal vagal state, also known as the “freeze state.” This is when immobilization and fear behaviors happen, and the heart rate and blood pressure may fall.
When You Feel a Glimmer
The goal is to reach the “top” of the ladder—the ventral vagal state, which is connected with social engagement and safety. This activates the parasympathetic nervous system (also known as rest-and-digest) and puts the body in homeostasis. Spending more time in this state reduces the risk of disease.
How Glimmers Work
The term “glimmer” was popularized by Deb Dana, LCSW. Triggers are cues—accurate or not—that move the body into those fight-or-flight or freeze states. Glimmers are also cues, but they are cues that move the body into that feeling of safety and connection and into the ventral vagal state.
While much of the activity on the polyvagal ladder is involuntary, it is possible to regulate your place on the ladder.
For example, something like breathing deeply can move you from fight or flight into the ventral vagal state and begin to down-regulate you. However, if you are in the dorsal (frozen) state, you need to first be moved into fight-or-flight before moving into the ventral vagal state.
How to Find More Glimmers
You can probably identify triggers in your life relatively quickly, but glimmers might be harder for you to access. It can be helpful to practice mindfulness or some kind of grounding activity before you attempt to discover your glimmers.
Discovering Your Glimmers
Think of a moment you had—no matter how fleeting it might have been—where you felt safe and connected, whether with yourself or with others. Glimmers will feel a little different in everyone’s bodies, but they’re generally those warm-and-fuzzy feelings where you feel cozy and safe.
Just as triggers can be both internal and external—from a thought of a traumatic situation that spontaneously comes up to a song that triggers intense feelings associated with a situation—so can glimmers. In fact, one person’s trigger might be another person’s glimmer.
How to Identify Your Glimmers
It can be helpful to keep track of your glimmers, just as you might keep track of triggers or other negative thoughts. You can do this in a journal or in a notes app on your phone. If you need help beginning to identify them, try these exercises below:
- Close your eyes and picture a moment of peace. This can be anything from a place you’ve been to, to somewhere you’ve only seen pictures of, to a place you’ve only seen in your imagination. You might want to go spend time there, have a picture of it readily available, or create a picture of it yourself.
- Think of what made you feel safe and cared for as a child. If there is a way you can access that as an adult. If you didn’t feel safe and cared for as a child, think of what you can do that you wish you had then. Is there someone who can give you a hug, or can you give yourself that hugging sensation by hugging yourself or snuggling under a weighted blanket?
- Think of a loved one. Picture someone you can just fully relax and be yourself around. If not, picture what having someone in your life like that might feel like. If it’s someone you know, spend time with them if you can or give them a call. If it’s not someone you know, watch a movie or listen to a song that reminds you of someone with these characteristics.
Takeaways
Glimmers might be small, but they can have a big impact on your mental health and well-being. By paying attention to the things that bring you joy, you can start to shift your focus away from feelings of stress and toward a greater sense of relaxation. The more you tune into these moments, the better you’ll be able to latch on to those feelings of safety and connection as you go about your day.
