What is a dysregulated nervous system? (And how to recognise it)
You wake up one morning and already feel tired before the day has even begun. Your breathing is shallow. You are irritable. Your body is switched 'on', even though there is no actual danger anywhere.
Many people recognise this. But few know there is a name for it: a dysregulated nervous system.
What does your nervous system actually do?
Your autonomic nervous system regulates everything you do not consciously control: your heart rate, your breathing, your digestion and, crucially, your sense of safety. It has two main modes.
The sympathetic branch is your accelerator. It prepares your body for action, effort or danger. The parasympathetic branch is your brake. It takes care of rest, recovery and connection.
In a healthy system, these two alternate smoothly. After a stressful meeting, you come home, breathe out and your body unwinds. That is regulation.
But with chronic stress, trauma or persistent overstimulation, that rhythm becomes disrupted. Your accelerator stays pressed. Or you get stuck in a third mode: the freeze response. Your body no longer shifts back to rest on its own.
How do you recognise a dysregulated nervous system?
There are no standard symptoms that look the same for everyone. Some people feel constantly tense and rushed. Others are chronically exhausted and barely feel anything at all.
Common signals include: difficulty relaxing even when at rest, sleep problems or light and restless sleep, tight muscles in the neck, jaw or shoulders, a sense of vigilance you cannot switch off, quick irritability or intense emotional reactions, concentration problems or a feeling of fog in your head, managing a full schedule while feeling completely empty inside.
That last one is characteristic of many people I work with. They function. They perform. But inside, everything is on edge.
Why this is not a 'mental' problem
This is one of the most liberating insights from somatic therapy: a dysregulated nervous system is not a weakness and not a mental disorder. It is a biological response from a body that has been surviving in demanding circumstances for years.
Bessel van der Kolk described it well: the body keeps the score. Unprocessed stress and trauma settle into the tissue. Into the breath. Into muscle tension. Into the way you experience life.
Talking helps, but it is not enough. You cannot think your way to regulation.
What helps with a dysregulated nervous system?
Regulation does not begin with willpower or insight. It begins with safety in the body. With small signals that let your nervous system know the danger has passed.
Somatic Experiencing works precisely at that level. Not by reliving trauma, but by teaching the nervous system to pendulate step by step between activation and rest. Small exercises, body-oriented attention and a safe therapeutic relationship are the key.
