Coresilience: How Inner Safety and Connection Build Resilience Together

When the heart closes to protect, we disconnect. 

Here’s how to find our way back to connection, and resilience. 

The other day I was watching a segment of Mayim Bialik’s Breakdown – her neuroscience-informed, mental health podcast with guest Stephen Porges. Porges is the much-admired and respected creator of The Polyvagal Theory.

I’ll admit I was in a gloomy mood. Feeling really down and hurt by the meteoric rise of antisemitism around the world — and very, very close to my home. The massive protests with hateful, violent chants. The gleeful intimidation. The vandalism. The bullying of children. The beatings. It’s sickening to my core. And Polyvagal Theory helps me understand what’s happening inside my brain and body when I find myself retreating within, withdrawing from social engagement, closing off.

One line Porges said struck me like a punch to the gut:

“The people who have survived trauma teach us about what it is to be human, by teaching us what they’ve lost – and they’ve lost the ability to feel safe enough with another.” — Stephen Porges

I know what it’s like to lose the ability to feel safe with another. I know how alone that feels. And I know the true gift it is to recover that ability — even if only in limited circumstances, even if it takes years.

That line sent me into a deep reflection about one of the most painful paradoxes in human experience: at precisely the moments when we most need the support of others — their presence, their warmth, their steadying influence — some of us simply cannot open up to receive it. Instead, we close. We isolate. We shut down to protect ourselves from the very connection we’re desperate for.

This piece is my attempt to explore why that happens — and what we can do about it. It moves through the neuroscience of safety and connection, arrives at a concept I’ve been developing called Coresilience, and ends with practical pathways for building it.

Why Safety Is Everything

When our bodies register safety, something remarkable happens. The nervous system shifts into a state of calm openness — not passivity, but genuine availability. We become capable of connection, curiosity, creativity, and care. Our brains release oxytocin and endorphins. We can think clearly, feel fully, and engage with the people around us from our best selves.

When our bodies register threat — even low-grade, ambient, chronic threat — all of that narrows. The system mobilizes for survival. Executive function decreases. Nuanced thinking becomes harder. We become more reactive, more defensive, more prone to seeing danger where there isn’t any. We pull back from the people who might otherwise help us.

This is not weakness. This is biology doing exactly what it was designed to do. The problem arises when the threat response becomes a permanent setting — when the nervous system has learned, from years of unresolved stress or adverse experience, that the world is not safe and people are not trustworthy. When protection becomes the default rather than the exception.

In that state, we lose access to our own potential. And we lose access to each other.

The Body’s Threat Detection System — And When It Misfires

Porges identified a process he calls neuroception — the nervous system’s continuous, unconscious scanning of the environment for signals of safety or danger. It operates below conscious awareness, running like a filter through which every experience, interaction, and relationship is perceived before the thinking mind has any say.

When neuroception is working well, it’s a remarkable system — subtle, fast, and largely accurate. It allows us to sense genuine safety in another person’s face, voice, and presence, and to open accordingly.

But neuroception can misfire. Trauma, adverse childhood experiences, chronic stress, and disrupted attachment relationships can all recalibrate the system toward hypervigilance — toward reading danger where there is none, toward registering safe people as threats, toward staying defended even when defense is no longer necessary.

The result is a person who may function effectively in many domains of life, but who cannot quite settle. Cannot quite trust. Cannot quite open to the connection that would help them most. Not because they don’t want to — but because their nervous system, running its threat detection program faithfully, won’t allow it.

This is not a character flaw. It is a learned response. And learned responses, unlike character, can change.

The need for connection and the need for safety are not opposites. But for many people, they have come to feel that way.

 

Regulation and Coregulation — We Were Never Meant to Do This Alone

Regulation — the capacity to move through activation and return to a settled, functional state — is not something we are born knowing how to do independently. We learn it through coregulation: the mutual influence and synchronization between nervous systems, particularly in early caregiving relationships.(You can learn more here: Beyond Stress Management.)

When an attuned caregiver responds to an infant’s distress with calm, warmth, and presence, they are doing something physiologically profound: their regulated nervous system is helping to regulate the infant’s. Over time, and with consistent repetition, the infant internalizes that capacity. They begin to develop their own ability to self-regulate — but only because they first experienced co-regulation.

Not all of us received that. When early coregulation was inconsistent, absent, or actively harmful — when caregivers were stressed, unavailable, unpredictable, or frightening — the developing nervous system had to find other ways to manage. Ways that were adaptive at the time, and costly later.

And coregulation doesn’t end in childhood. Throughout our lives, we continue to regulate — and dysregulate — each other. The calm, open presence of a trusted person can settle our nervous systems in ways we cannot always achieve alone. The activated, defended presence of a frightened or hostile person can do the opposite. We are continuously influencing each other’s physiological states, whether we’re aware of it or not.

Which makes the quality of our own inner state — how regulated, how safe, how open we are — not just a personal matter. It is something we offer, or fail to offer, to everyone we’re in relationship with.

The Conundrum of Coregulation

Here is the painful paradox at the heart of this piece: the people who most need the regulating presence of a safe other are often the least able to fully receive it.

For individuals carrying unresolved attachment wounds, chronic stress, or trauma, the very act of opening to another person can feel physiologically impossible. The nervous system that most needs connection is the one most defended against it. The heart that most needs warmth is the one most protected by walls.

And the cycle is self-reinforcing. The more disconnected we feel, the more we retreat. The more we retreat, the more isolated we become. The more isolated we become, the more our nervous system’s threat detection system confirms its darkest assumptions about the world and other people.

Breaking this cycle requires something counterintuitive: building safety from the inside first. Cultivating enough internal regulation that connection becomes possible again — not because the world has become safer, but because we have become steadier within it.

That inside-out journey is what I call Coresilience.

The term draws on coregulation — the mutual influence of nervous systems — but points to something that must happen first: the cultivation of enough inner safety that we can show up as a regulated presence rather than adding dysregulation to dysregulation.

Coresilience is not self-sufficiency. It is not the goal of needing no one. It is almost the opposite: it is the inner work that makes genuine interdependence possible. The preparation that allows us to both give and receive the regulating gift of safe connection.

And it begins — as so much of this work does — with the heart.

The Heart as a Physiological Instrument

The heart is not just a pump. It is a primary interface between the nervous system and our experience of safety, connection, and wellbeing. The vagus nerve — the wandering nerve at the center of Polyvagal Theory — connects directly to the heart, making it one of the most accessible entry points for shifting our physiological state.

Heart Rate Variability (HRV) — the natural variation in time between heartbeats — is one of the most reliable indicators of nervous system health and resilience. High HRV reflects a flexible, well-regulated system. Low HRV reflects a system under strain, locked in defense, depleted by chronic stress.

What the HeartMath Institute has demonstrated — and what I use with clients and in my own daily practice — is that we can actively influence our HRV through heart-centered practices: rhythmic breathing combined with a deliberate shift of attention to the heart area, while cultivating genuine positive emotion. Appreciation. Gratitude. Care. Compassion.

When HRV patterns become smooth and ordered — what HeartMath calls coherence — the body enters a state of psychophysiological harmony. Mind, heart, and nervous system working together rather than against each other. In this state, we are more clear-headed, more emotionally available, more genuinely present with the people around us.

We become, in other words, a safer other. A regulating presence. Someone whose nervous system, by virtue of its own coherence, offers something to the nervous systems of those nearby.

That is Coresilience in practice.

Coresilience is not self-sufficiency. It is the inner work that makes genuine connection possible.

 

Building It: Where to Begin

Coresilience is built through practice. Not one practice — a range of them, because different people find their way in through different doors. What follows is a curated set of pathways, not a prescription. Start with one or two that feel accessible. Build gradually. Consistency matters more than comprehensiveness.

The practices are organized in two stages: first, building inner safety and regulation on your own — because the foundation must be laid before the bridge can be built. Then, gradually and intentionally, extending that safety outward into connection with others.

Stage One — Building Safety Within (Solo Practices)

Stage Two — Extending Safety Outward (Coregulation with Others)

Start where safety is most accessible — even if that means starting with an animal. There is no hierarchy here. What matters is beginning.

A note on getting support: If the conundrum of coregulation resonates — if you recognize the cycle of needing connection but feeling unable to access it — working with a trauma-informed coach or therapist can help you build the inner safety that makes the rest possible. HeartRich Resilience Coaching is designed specifically for this work.

A Journey Back to the Heart

Coresilience is not a destination. It is a direction — a daily practice of returning to your own steadiness so you can be genuinely present with others, and genuinely open to what they offer in return.

It begins in the body. It builds through the heart. It expresses itself in relationship — in the quality of attention you bring to another person, in your capacity to stay present with their difficulty without being consumed by it, in the quiet gift of your own regulated nervous system offered to theirs.

When we feel the world closing in — when fear and hostility and division make it tempting to shut down and withdraw — Coresilience is the practice of choosing, deliberately and repeatedly, to stay open. Not naively. Not without boundaries. But open. Because the alternative — the closed heart, the defended presence, the disconnection from others and from ourselves — is a cost too high to keep paying.

We heal in connection. We grow in connection. We become more fully ourselves in the presence of those who are safe enough to let us.

That’s what this work is for. And it’s available to you.
