When Your Brain Reacts Before You Think
The Moment Between the Two Brains (And Why We Lose Ourselves)
When Your Brain Goes Downstairs: People Pleasing, Overeating, and SurvivalToday I want to go a little deeper into something we’ve been talking about…
the upstairs brain and the downstairs brain.
And I want to make this really practical today.
Because once you start seeing this pattern, you start noticing it everywhere.
Not just in big emotional moments…
but in small everyday reactions too.
over-explaining in conversationspeople pleasingsnapping and then regretting itshutting down emotionallyovereating without even feeling hungryscrolling for longer than you meant toor feeling overwhelmed and just needing to escapeAnd what I find so fascinating is this…
All of those behaviors are actually connected to the same nervous system response.
The Two Brain Systems (Simple Explanation)
So when we talk about the upstairs and downstairs brain, we’re really talking about two systems in the brain working at different speeds.
Downstairs Brain (Survival System)
This includes things like the amygdala, the brainstem, and other fast-acting survival structures.
And this part of the brain is quick.
It scans for anything that feels like danger—not just physical danger, but emotional or social danger too.

And the downstairs brain reacts instantly:
“Fix it.”“Get out of this.”“Make it better quickly.”“Do something now.”Upstairs Brain (Thinking + Regulation System)
The upstairs brain is mainly the prefrontal cortex.
This is the part that helps you:
think clearlypause before reactingregulate emotionsconsider perspectivemake intentional choicesThis is your grounded, wise self.
The part of you that can say:
“Let me slow down here.”
“I don’t need to react immediately.”
“I can choose how I want to respond.”
The Important Truth: They Work at Different Speeds
The downstairs brain is fast.
The upstairs brain is slower.
So in moments of stress, the emotional system often activates first.
Before we even think about it.
And sometimes it temporarily reduces access to clear thinking.
This is often called an amygdala hijack—when the survival system takes over before the thinking system can fully engage.
And that’s why it can feel like:
“I know better… but I still reacted that way.”
The Moment Between the Two Brains
And here’s what I find really fascinating…
There is a moment between the two brains.
And that space is where everything changes.
Because in that moment, you can either:
go downstairs into reaction…
or stay upstairs long enough to choose your response.
But most of us were never taught how to stay in that pause.

Reaction over reflection.
What Going “Downstairs” Actually Looks Like
And this is where it gets really interesting…
Because going downstairs doesn’t always look dramatic.

Sometimes it shows up in how we try to regulate ourselves.
The Nervous System’s Search for Relief
Because here’s something really important…
When the downstairs brain is activated, it is not just trying to think.
It is trying to feel better quickly.
So it will reach for anything that creates immediate relief.
And that’s where we see patterns like:
overeatingemotional eatingscrolling on our phonenumbing out with distractionspeople pleasingover-functioningor staying constantly busyAnd what’s so important to understand is this:
These are not random habits.
They are nervous system regulation strategies.
Overeating and the Downstairs Brain
Let’s talk about overeating for a moment.
Because this is something so many people experience quietly.
When the nervous system feels overwhelmed, stressed, lonely, or emotionally full…
the downstairs brain starts looking for fast comfort.
And food is one of the quickest ways the brain knows how to change how we feel.
increase dopamine (pleasure chemicals)create soothing sensationstemporarily reduce stressand bring a sense of comfort or groundingSo the brain learns:
“This helps me feel better quickly.”
Not because something is wrong with you…
but because your nervous system is trying to regulate itself.
And in that moment, the upstairs brain—the reflective part of you—has less access.
“Am I hungry?”“What do I actually need?”“Am I tired or overwhelmed?”the system is just asking:
“How do I feel better right now?”
That’s downstairs brain thinking.
Why This Is Not About Willpower
And I really want to be gentle here…
Because this is not a willpower issue.
This is not about discipline.
This is about a nervous system trying to find relief from internal discomfort.
And when we understand that, everything shifts.
Because now we’re not asking:
“What’s wrong with me?”
We start asking:
“What am I feeling that I don’t know how to hold right now?”
Why Women Especially Experience This
And I think this is especially true for women.
Because many women are constantly managing:
emotions in relationshipsfamily needsexpectationsemotional environmentsand internal pressure to keep everything okaySo the nervous system becomes highly sensitive to:
tensiondisappointmentconflictemotional shifts in othersAnd that can create a brain that goes “downstairs” very quickly.
And then tries to restore safety quickly.
Through people pleasing…
or overeating…
or over-functioning…
or emotional shutdown.
The Real Healing Point: Awareness of the Pause
It’s not eliminating emotion.
It’s not never going downstairs.
The healing point is awareness.
Because once you can notice:
“Oh… I’m downstairs right now.”
You create the possibility of coming back.
And that moment—that awareness—is everything.
The Pause Is a Biological Skill
That pause between reaction and response is not just emotional maturity.
It is your nervous system learning regulation.

And this is where I always come back to creativity.
Because creativity naturally slows the nervous system.

You move from reaction…
into presence.
And in that presence, you start hearing yourself again.
Not fear.
Not urgency.
Not pressure.
And sometimes in that space, you realize:
“I’m more overwhelmed than I thought.”“I’ve been carrying too much.”“I’ve been reacting all day without noticing.”“I actually need something different.”Creativity gives you access to awareness before reaction.
So maybe the question isn’t:
“How do I stop reacting?”
“Can I notice when I’m reacting… just a little sooner?”
Because the upstairs brain is not far away.
It just gets harder to access when the downstairs brain is loud.
But it always returns through:

You begin to respond to it.
