Understanding Your Nervous System: Safety, Stress and Regulation
Regulation isn't about always feeling calm. It's about having the flexibility to respond, recover and reconnect
Our nervous system is constantly responding to what is happening around us — and within us.
Long before we consciously decide how we feel about something, our nervous system is taking in information and responding to cues of safety, danger or uncertainty.
These responses can influence our breathing, heart rate, muscle tension, emotions, attention and how we relate to other people.
What does Nervous System Regulation mean?
We often hear about the importance of regulating our nervous system, but regulation doesn't simply mean being calm all the time.
Our nervous system needs to be able to move between different states depending on what is happening.
Sometimes we need energy and mobilisation to respond to a challenge. Sometimes we need to rest. And when we feel safe, we can be more available for connection, curiosity, communication and engagement.
The goal isn't to stay permanently calm.
It's about having flexibility — being able to respond to what is happening and return to a sense of safety when the threat has passed.
When our nervous system gets stuck in protection
When we've experienced ongoing stress or trauma, our nervous system can become more sensitive to cues of threat.
We might find ourselves constantly alert, tense or ready to react. Or we might go in the opposite direction and feel numb, shut down or disconnected.
These responses aren't weaknesses or failures.
They are protective responses that have developed for a reason.
Sometimes the difficulty is that our nervous system continues to respond to threat even when the original danger is no longer present.
This can leave us reacting automatically to situations that, consciously, we know are safe.
Safety isn't just something we think
We can tell ourselves "I'm safe" while our body is still tense, guarded or preparing for something to happen.
Our nervous system is constantly taking in information from our surroundings, our relationships and our own internal experience. Some of these responses happen outside of our conscious awareness.
This helps explain why simply telling ourselves to "calm down" doesn't always work.
Our bodies may need experiences of safety, connection and support — not just an intellectual understanding that we are safe.
Regulation can happen through connection
Regulation isn't something we always have to do alone.
Our nervous systems are influenced by our interactions with other people. The tone of someone's voice, their facial expression, body language and the quality of a relationship can all affect how safe or threatened we feel.
This is one reason that feeling genuinely safe with another person can be so powerful.
In therapy, the relationship itself can become part of the experience of safety.
What does this mean for Somatic Therapy?
This understanding of the nervous system is one reason I incorporate somatic approaches into my work.
Rather than seeing our reactions as something we simply need to control, we can become curious about them:
What is my body responding to?
Does this response belong to what is happening now, or does it feel familiar from somewhere else?
What helps me feel more grounded, connected or present?
The aim isn't to force the nervous system into a particular state. It is to develop greater awareness, flexibility and choice.
And importantly, regulation isn't about never feeling stressed, anxious or overwhelmed. These are normal human responses.
It is about developing the capacity to move through different states and, where possible, return to a sense of safety and connection.
Regulation isn't about being calm all the time
We don't need to eliminate difficult emotions or keep ourselves in a state of calm.
Our nervous system is designed to respond to what life asks of us.
Sometimes we need to mobilise. Sometimes we need to protect ourselves. Sometimes we need to rest and recover.
The aim isn't to stop these responses. It's to develop greater flexibility in how we move through them.
When we understand our nervous system in this way, we can begin to meet our responses with curiosity rather than judgement — and recognise that even the responses we find difficult may have developed as ways of protecting us.
