I was reflecting recently on something I’ve felt myself and seen in many clients: that even when you know your relationship is over, your body might still ache with a different kind of grief — the loss of the other body. The loss of the nervous system pattern you've known.

You see when we end a long term relationship, whether it be an intimate or close platonic relationship, it is not only the financial and logistical separation and negotiation that happens. Our bodies keep the score and there is a physical separation of nervous systems that have entrained to each other.

Our nervous systems attune to the bodies we live with. Even if the relationship was painful or over long ago, your body might still long for their touch, their presence, even their smell.

This isn’t about wanting the person back — it’s about missing the co-regulation, the shared rhythm your nervous systems built together. It’s why sleeping alone can feel painful. Why your skin aches. Why you cry and you don’t know why.

Entrainment is when two nervous systems get in sync with each other, a bit like two clocks ticking together or two metronomes lining up. When you live with someone, your breath, heart rate, stress patterns, and even sleep rhythms start to line up with theirs. Your bodies learn each other. That’s why, when they’re gone, your body still remembers that pattern — and it can feel strange or even painful until you find a new rhythm.

The entrainment of nervous systems, especially in close relationships, is such a subtle and powerful force. It’s part of why even dysregulated relationships can be hard to leave — because the body gets patterned into that rhythm, even if it’s chaotic or unpredictable. I some times think of this phenomena as co-dysregulation.

In healthy relationships, this entrainment creates a deep sense of safety and grounding. But in any relationship with proximity over time, the nervous systems begin to sync — breath to breath, step to step, sleep cycles, even hormone levels. It's primal. It's ancient. And when it’s gone, the body doesn’t just let go because the mind says it should.

When this stops, the body reacts with disorientation, grief and longing.

This isn’t about missing the person romantically or doubting the decision. It’s about the withdrawal of co-regulation — a physical and energetic loss. Where there was once a warm body, there is now space. The nervous system goes through a recalibration, and sometimes, a kind of withdrawal.

We can experience shame and confusion around this.

Many people feel embarrassed or confused by their grief, especially if they initiated the separation or felt clear. They may wonder: “Why am I crying? Why does my chest ache? Why do I feel so alone? It is important to normalise that this is nervous system memory, not a sign that they’ve made the wrong choice.

What are some practices that can support you?

Orient to touch — a hand on the heart, a warm wrap, a pillow beside your body in bed.
Use scent, rhythm, and sound to create new patterns of regulation.
Let the body feel the grief — let the tears, the ache, the longing move. The body needs to move downward to express grief so sometimes, lying on a soft nest of pillows can be a really supportive way to do this.
Use nature, animals, breath, or trusted others to co-regulate in new ways.

Remember, relationships ending can be both a liberation and a loss. Our bodies are sometimes slower than our minds when it comes to moving on and they ask us to honour what was, whilst we are moving into what is next for us.

The invitation here is to trust the wisdom of your body and honour this unique grief without judgment.

For centuries, humans have told themselves a story: that we stand apart from nature. We build cities, design technologies, and shape landscapes to meet our needs. We name ourselves as observers of nature, as though it is something out there—separate from us. But this illusion of separation is just that—an illusion.

The truth is, we are not just in nature. We are nature.

We have this myth of separation, a mental model that we hold that we are separate to nature. We need sunlight, water and oxygen to survive. We take all that in, plus food (from nature) and we breath out carbon dioxide which the trees take in to make oxygen. We are a system living within a system.

Somewhere along the way, many human cultures began to see nature as something to be tamed, managed, or extracted from. The industrial revolution accelerated this thinking, and modern life often reinforces it. We go from temperature-controlled homes to air-conditioned cars to office buildings, rarely touching the earth with bare feet or feeling the true rhythm of the seasons.

But no matter how much concrete we pour, how many walls we build, or how advanced our technology becomes, we are still living, breathing organisms shaped by the same forces that shape the forests, the rivers, and the wind.

Our bodies speak the language of the earth even, when we forget our connection, our bodies remember.

We have our own rhythms and cycles just liken nature, some of these are:
- The circadian rhythms that govern our sleep are tuned to the rising and setting of the sun.
- Our lungs evolved in partnership with trees, exchanging oxygen and carbon dioxide in a continuous, reciprocal dance.
- The minerals in our bones were once part of ancient mountains.
- The water that makes up most of our bodies has cycled through clouds, rivers, and oceans for billions of years.

We are the land, the sea, the sky—just temporarily arranged in the form of human beings.

Human beings are relational beings, we are wired for connection and we need other people around us to co-regulate our nervous systems - we are not wired to do life on our own. In nature, everything is relational. Forests are not just collections of trees; they are living systems where roots exchange nutrients, fungi form underground networks of communication, and birds and insects pollinate plants, sustaining the whole.

Humans, too, are part of these systems. We have always been in relationship with the land, with animals, with each other. Indigenous cultures have long recognized this interdependence, honoring the earth not as a resource to exploit, but as kin to respect.

When we embrace this view, our decisions shift. We stop seeing ourselves as rulers of nature and instead become participants—stewards in an ancient, living network.

So how do we connect back to our natural place in nature?

Remembering our place in nature is not about abandoning modern life. It’s about reweaving our awareness into the fabric of the world.

We can start small:
- Walking barefoot on the earth, this is one of my favourites and I often do laps each night in a park in my house,
- Swimming in natural bodies of water,
- Noticing the phases of the moon,
- Eating food that actually comes from the soil, not just a package,
- Listening to birdsong in the morning.

Our body actually loves being in nature and connecting with the earth helps to anchor us back down into our bodies when the daily machinations of modern life and technology lift us out of it.

These simple acts reconnect us to something ancient within ourselves. They remind us that we are not just visitors here—we belong. Whilst these are great activities we can do on our own, they are even better when we do them with friends. We build little spots of coherence in our life with these activities and coherence has the capacity to shift a system. Coherence. both within our nervous system and in ecosystems, act as small attractors and they pull the system toward greater organisation. This is because systems are often fractal, which means that small patterns reflect and influence the larger whole.

So in a system that is dysregulated, a single stable rhythm, like a leader modelling nervous system regulation in a group, can influence a group to entrain to steadiness and calm.

Our nervous system is not separate from nature—it is nature. The same principles that govern ecosystems also govern our inner world:

Just as a forest needs diversity and resilience to thrive, our nervous system needs a range of experiences and emotions to stay regulated..

Just as a river adapts to the landscape it moves through, we heal by allowing our emotions and sensations to flow rather than becoming stagnant.

Just as animals shake off stress to reset their systems, we can release stored trauma through therapeutic modalities like somatic experiencing that work with the natural rhythm of the body and we can use somatic practices that restore regulation

How do we come home to ourselves?

The climate crisis, biodiversity loss, and ecological destruction we face today stem, in part, from our belief in separation. But if separation is the problem, then reconnection is the medicine.

When we stop seeing nature as something outside of us and start feeling it within us—as us—we open the door to a different way of living. A way that honours interdependence. A way that leads us back home.

Because we were never separate. We just forgot.

Now is the time to remember. Although we face many big global problems, act as that small port of coherence, start local. Start with yourself and in your systems you interact with.

Do you ever wonder why breakups physically hurt even when we are over the person?

The web of life, we are not just in nature, we are nature.
