Understanding Your Nervous System: Why You Feel Wired, Frozen, or Calm
By Jordan, Psychologist · · 7 min read
What does the nervous system actually do?
Your autonomic nervous system works below conscious awareness. It regulates your heartbeat, breathing, digestion, and, importantly, your sense of safety. Many seconds before you have a thought about a situation, your body has already decided whether it feels safe.
Therapists often describe three broad states: a calm, connected state where you feel present and able to engage; a mobilised state (fight or flight) where you feel anxious, irritable, or restless; and a shutdown state (freeze) where you feel numb, exhausted, or disconnected.
Signs your nervous system is dysregulated
Dysregulation shows up in the body and in behaviour. Common signs include:
- A racing heart, shallow breathing, or a tight chest
- Feeling constantly on edge, jumpy, or irritable
- Difficulty sleeping, or waking up already tired
- Numbness, brain fog, or feeling far away from yourself
- Overreacting to small things, then feeling ashamed afterwards
Why expats often feel more dysregulated
Moving countries removes many of the cues your nervous system relies on to feel safe: familiar language, routines, food, faces, and support networks. Even exciting moves are experienced by the body as a lot of uncertainty. Feeling more anxious or tired during your first years abroad is a normal response, not a personal failure.
Simple ways to regulate your nervous system
These practices send your body signals of safety. Try one for two minutes a day:
- Longer exhales: breathe in for 4, out for 6 to 8. A long exhale slows your heart rate.
- Orienting: slowly look around the room and name five things you see.
- Movement: shake out your arms, walk, or stretch to release mobilised energy.
- Temperature: cool water on your face or a warm drink can shift your state.
- Safe connection: a kind voice, a hug, or a message to someone you trust.
When to seek therapy
If you feel stuck in anxiety or shutdown for weeks, or if past experiences keep flooding your body, therapy can help. Approaches such as EMDR and Schema Therapy work with both the memories and the body responses that keep you on high alert.
Frequently asked questions
What is nervous system regulation?
Nervous system regulation is the ability to move out of stress states like fight, flight, or freeze and return to a calm, connected state. It is a skill that can be strengthened with practice and therapy.
How long does it take to regulate the nervous system?
Short practices like slow breathing can shift your state within minutes. Building lasting resilience, especially after trauma or chronic stress, usually takes weeks to months of consistent practice and support.
Can therapy help a dysregulated nervous system?
Yes. Trauma-informed therapies such as EMDR help the brain reprocess distressing memories so the body no longer reacts as if the danger is still happening.
