The Nervous System
Your nervous system is constantly asking one question:
Am I safe right now?
The answer affects how you think, feel, connect and respond.
Your body's built-in protection system
Your nervous system never really clocks off. Every second of every day it's quietly taking in what's happening around you and asking one question:
​
"Am I safe?"
​
Not just physically. Emotionally too.
​
Can I relax here? Do I belong? Am I accepted? Am I about to be criticised, rejected, embarrassed or ignored?
What does "safe" actually mean?
When we hear the word safe, most of us think about physical danger. A car accident. A fire. A snake.
​
Your nervous system thinks about those things too, but it's also paying attention to emotional safety.
It notices whether you feel accepted, whether conflict is brewing, whether you're about to be judged or whether something reminds you of a difficult experience from the past.
Your body doesn't always separate physical danger from emotional danger. It just responds to what it has learnt.
Why we all respond differently
That's why two people can experience the exact same situation and react completely differently. One person hears feedback. Another hears rejection. One person sees a disagreement. Another feels unsafe.
Neither response is wrong. They're shaped by different experiences.
Your body's smoke alarm
Imagine your house had a smoke alarm that had learnt to go off every time you made toast.
​
The toast isn't dangerous, but the alarm doesn't know that. It's only doing what it learnt to do.
​
Our nervous systems can work the same way. They learn from experience. If something once felt unsafe, your body remembers it and starts looking out for it in the future.
​
That means criticism might make your stomach drop before you've even had time to think. A disagreement can suddenly feel much bigger than it is. Being left on read can bring up a feeling that's far older than the text message itself.
​
Your body isn't trying to make life harder. It's trying to keep you safe.
Sometimes the smoke alarm is just a little more sensitive than it needs to be.
You might recognise yourself...
Your boss says,
"Can we have a quick chat?"
By the time you've walked to their office you've convinced yourself you're in trouble.
​
Your friend takes a day to reply.
Logically you know they're probably busy, but your body starts wondering if you've done something wrong.
Someone raises their voice.
Before they've even finished their sentence, your shoulders tense and your heart starts racing.
Someone gives you feedback.
Another person hears helpful advice.
Your body hears danger.
Every reaction is your smoke alarm doing its job.
The question isn't, "What's wrong with me?"
It's, "Why has my smoke alarm gone off?"
Fight, Flight, Freeze & Fawn
When your nervous system thinks something isn't safe, it gets your body ready to protect you.
That protection can look different for everyone.
​
Fight
"I'll prove I'm right."
"I snap before I've even thought."
"I get defensive."
"I can't let this go."
​
Flight
"I'll do it tomorrow."
"I suddenly need to clean the house."
"I avoid replying."
"I keep myself busy."
​
Freeze
"I don't even know where to start."
"I stare at the screen."
"My mind goes blank."
"I feel completely stuck."
​
Fawn
"It's fine."
"Whatever you want."
"I'm sorry."
"I'll keep everyone happy."
​​
These aren't personality traits.
​
They're protective responses.
The good news is your nervous system can keep learning.
Just because your body learnt something years ago doesn't mean it has to stay that way forever.
Every time you notice your smoke alarm going off, take a look around. Feel your feet on the ground. Look for what's actually happening right now and remind yourself, "I'm here. I'm safe. That moment has passed."
​
Every time you do that, you're giving your nervous system new information.
Little by little, it starts learning that not everything that feels dangerous actually is.
The smoke alarm doesn't disappear, but it becomes better at telling the difference between real danger and old memories.
Your body knows you're overwhelmed before your mind has found the words for it.
