If you have spent any time in healing spaces — therapy, trauma recovery, wellness communities — you have likely heard the word trigger.

You probably have a sense of what it means: something that activates a stress response, that pulls you back into an old feeling, that makes your nervous system behave as though the past is happening right now.

But there is another word that does not get nearly as much attention — one that is just as important, and considerably more hopeful.

That word is glimmer.

A trigger is any cue — sensory, emotional, relational, or situational — that activates the nervous system's threat response. It is not a weakness or an overreaction. It is the nervous system doing exactly what it was designed to do: scan for danger and respond accordingly.

For people who have experienced trauma, the nervous system's threat-detection system can become highly sensitized. It learns to associate certain stimuli — a tone of voice, a particular smell, a feeling of being watched, a sudden loud sound — with danger, even when the current situation is safe. The response happens before the thinking brain has a chance to weigh in.

This is why you cannot simply decide not to be triggered. The response is not a choice. It is a learned pattern, held in the body, that developed for good reason.

Common triggers might include:

• Raised voices or conflict
• Feeling ignored, dismissed, or unseen
• Being touched unexpectedly
• Certain smells, songs, or places associated with difficult memories
• Feeling out of control or uncertain
• Perceived criticism or rejection

Understanding your triggers is not about cataloguing everything that is wrong with you. It is about developing compassion for a nervous system that learned to protect you — and beginning, slowly, to teach it that safety is possible.

The concept of glimmers was introduced by therapist Deb Dana, who works extensively with polyvagal theory — a framework developed by Dr. Stephen Porges that describes how the nervous system moves between states of safety, mobilization, and shutdown.

A glimmer is the opposite of a trigger. It is a small, often subtle cue that signals safety to the nervous system. A micro-moment that shifts your body toward regulation, connection, and ease.

Glimmers are not grand experiences of joy or peak moments of happiness. They are quieter than that. They are:

• The warmth of sunlight on your face through a window
• The sound of rain
• A particular song that opens something in your chest
• The smell of coffee in the morning
• A moment of genuine eye contact with someone you trust
• The feeling of your feet on cool grass
• A pet settling against you
• A breath that reaches all the way to your belly

You may have noticed these moments without knowing what to call them. A brief softening. A small exhale. A flicker of something that feels, for just a second, like okay.

That is your nervous system registering safety. That is a glimmer.

For a long time, trauma-informed work focused primarily on identifying and working through triggers. And that work is essential. But an exclusive focus on what activates the threat response can inadvertently reinforce the nervous system's orientation toward danger.

Glimmers offer a different entry point.

When you begin to notice and intentionally seek out glimmers, you are doing something neurologically significant: you are building what researchers call positive neural pathways — patterns of safety and regulation that the nervous system can return to. You are, in a very real sense, teaching your body that good things exist. That safety is not just the absence of threat, but a felt experience that can be cultivated.

This does not erase trauma. It does not make triggers disappear. But over time, a practice of glimmer awareness can expand your window of tolerance — the range within which your nervous system can function without tipping into overwhelm or shutdown. It gives you more ground to stand on.

The first step is simply awareness — without pressure to change anything.

For triggers: When you notice a strong reaction — anxiety, shutdown, anger, dissociation — see if you can get curious rather than critical. What just happened? What did my nervous system perceive as a threat? You do not have to answer fully. Just the act of asking with compassion rather than judgment begins to shift the relationship.

For glimmers: Start small. Once a day, see if you can notice one moment that brings even a slight sense of ease or warmth. It does not have to be significant. It just has to be real.

Over time, you might keep a simple record — a few words in a notebook, a note on your phone. Not to perform gratitude, but to train your attention toward what is also true: that alongside the hard things, there are small moments of safety. They have always been there. You are simply learning to see them.

I have created a free triggers vs. glimmers check-in worksheet to help you begin mapping your own nervous system landscape — gently, at your own pace, with prompts that support both awareness and self-compassion.

It is a simple, printable resource you can use on your own or alongside therapy. No experience with polyvagal theory required.

Your nervous system is not broken. It is doing its best with what it learned. And it can learn something new — one small moment of safety at a time.
