We live in a world where stress has quietly become a background state.
And yet our nervous system holds a remarkable capacity to return to balance, when the right conditions are met. Polyvagal theory, developed by the neuroscientist Stephen Porges, helps us understand how the body perceives safety, handles stress, and shapes our emotions.
It also sheds a precious light on the role of breath, touch and movement in creating new bodily experiences — ones capable of changing our inner state for good.
Three states, not two
Our autonomic nervous system is not a simple switch between stress and relaxation. It moves between several states that shape our thoughts, our feelings and our behaviour.
Safety and connection
When we feel safe, the nervous system supports social connection, curiosity, creativity and the capacity to be in relationship. The body is relaxed — and still available, still alive.
Mobilisation
Faced with a perceived threat, survival mechanisms switch on. The heart quickens, breathing shortens, muscles prepare for action. This can show up as anxiety, agitation or hypervigilance.
Immobilisation
When the threat feels insurmountable, the nervous system can drop into a deeper form of protection: fatigue, lack of energy, a sense of disconnection, withdrawal.
None of these are conscious choices. They are biological strategies, designed to keep us alive.
Stress is a question of perceived safety
Our nervous system is constantly scanning the environment to work out whether we are safe or in danger. This automatic process — neuroception — happens entirely outside our awareness.
So even when no real danger is present, certain situations, memories or bodily tensions can be read as threatening. The body responds as though it had to protect itself.
Emotional regulation, then, is not about controlling or suppressing emotion. It is about helping the nervous system find enough safety to come out of survival mode.
Breath: a bridge to calm
Breathing is the most accessible way we have to influence the nervous system.
When we deliberately slow the breath — and particularly the exhale — we stimulate the vagus nerve, which sits at the centre of polyvagal theory. That stimulation sends the brain a simple, powerful message:
“All is well. You can let the watchfulness go.”
Conscious breathing can lower stress activation, support a return to calm, sharpen bodily awareness and underpin emotional regulation. The breath becomes a language we use to speak with our own nervous system.
Touch: a message of safety
Kind touch is one of the very first forms of communication we ever experience.
When it is respectful, safe and attuned to the person, touch sends reassuring information to the nervous system. It helps release muscular tension, slow the heart rate, and support the hormones associated with wellbeing and attachment.
The body receives a concrete experience of safety — one that can reach what words alone cannot soothe.
Movement: completing the survival response
Stress and difficult experiences leave traces in the body. Responses of flight, fight or protection can remain unfinished, keeping the nervous system on alert.
Gentle, conscious movement offers the body new possibilities of expression. Walking, stretching, mobilising the pelvis, moving fluidly — all of it can restore a sense of vitality and safety.
Movement does not only act on muscles. It tells the brain that the body now has more resources to meet what life brings.
Writing new messages
For a long time we believed the brain mostly directed the body. Neuroscience now shows the conversation runs both ways.
When we breathe consciously, receive safe touch or move in an attuned way, we create new sensory experiences. Those experiences become new nervous messages that enrich the system's sense of safety.
Little by little, the body learns there are other options than tension, hypervigilance or withdrawal. New pathways can form — supporting more calm, more presence, more resilience.
Caring for your nervous system is learning to listen
to the deep intelligence of the body —
and giving it back the conditions it needs to flourish.
