We’ve been taught to think about physical and mental health as separate.
Body over here. Mind over there.
But the body doesn’t experience itself that way.
And neither do we.
More and more, neuroscience is pointing to something that many of us already sense: our emotional life is not separate from our physical state. It’s shaped by it.
Not entirely. But significantly.
I don’t believe we can resolve all of our emotional or relational struggles by optimizing our physical health. That’s too simplistic.
But I do believe this:
If we ignore the body, we make our inner world harder to understand.
One of my scientific anchors here is Lisa Feldman Barrett, particularly her work in How Emotions Are Made.
Her research challenges the idea that emotions simply “happen” to us.
Instead, she points to something more foundational.
Before emotion, there is sensation.
Before story, there is state.
Your brain is in constant conversation with your body—tracking signals from your organs, your bloodstream, your nervous system. This process is called interoception.
Most of the time, we’re not consciously aware of it.
But we feel it.
As a general tone.
A background sense of how we are.
In psychology, this is often referred to as affect—the simple experience of feeling pleasant or unpleasant, calm or activated.
Not joy. Not grief. Not anger.
Just… the baseline.
And that baseline is shaped, in part, by what Barrett calls the “body budget”—whether the body is resourced or depleted.
Hydrated or not.
Rested or exhausted.
Nourished or under-fueled.
Regulated or taxed.
This matters more than we tend to admit.
Because when that baseline shifts, everything built on top of it shifts too.
The same conversation feels different.
The same problem feels heavier.
The same thought becomes more convincing.
And yet, when something feels off, most of us don’t start with the body.
We start with meaning.
What’s wrong?
What did I do?
What’s happening in my relationship?
Sometimes those are the right questions.
But not always the first ones.
There are moments when a more honest question is:
What state am I in right now?
Have I slept?
Have I eaten?
Have I been moving?
Have I been pushing past my limits?
This isn’t reductionistic.
It’s orienting.
It’s a way of getting honest about the conditions we’re living inside of.
And there’s something else that matters here.
The way we work with this information.
Because it’s easy to take something like this and turn it into another project of self-improvement. Another place to try harder, do better, get it right.
That’s not what I’m pointing to.
Physical health is not something we master.
It’s something we relate to.
Slowly. Imperfectly. Over time.
Small changes tend to be the ones that last:
drinking more water, getting more sleep, moving your body in ways that feel doable, eating in a way that actually supports you.
Not perfectly.
Just consistently enough.
Because even small shifts in how we care for the body can stabilize the ground we’re standing on.
And when the ground is more stable, we have more capacity.
More room to feel.
More room to think clearly.
More room to respond instead of react.
There is always more to our emotional and relational lives than our physical state.
But the body is often the most immediate place to begin.
Not because it solves everything.
But because it changes the conditions we’re working within.
And that matters.
