First Responder PTSD: When You Can’t Switch Off
By: Jamie Gahagan, MACP
You’re Off Shift. Your Nervous System Isn’t.
For first responders, the call may be over—but sometimes your body doesn’t get the message.
You’ve finished your shift.
You’ve changed out of your uniform.
You’ve driven home.
You’ve walked through the front door.
But you still feel like you’re waiting for the next call.
You’re tired, but you can’t fully relax. You’re exhausted, but sleep doesn’t come easily. A noise outside makes you instantly alert. You find yourself checking things, scanning your surroundings, or feeling uncomfortable when everything is quiet.
And sometimes, you don’t even realize how much you’re doing it.
This can be part of what trauma and PTSD look like for first responders.
When Being “Ready” Becomes Your Default
As a first responder, being alert is part of the job.
You’re trained to notice things other people might miss. You’re prepared to respond quickly. You know that situations can change in seconds.
That heightened awareness can be incredibly useful when you’re working.
The problem is when your nervous system starts treating everyday life like another emergency.
You may notice:
Feeling constantly on guard or hypervigilant
Being easily startled by sounds or movements
Difficulty relaxing or sitting still
Trouble falling or staying asleep
Irritability or feeling like your patience is running thin
Feeling uncomfortable when you aren't in control
Replaying calls or traumatic events in your mind
Avoiding certain places, conversations, or situations
Feeling emotionally numb or disconnected
Difficulty being fully present with your partner or family
Feeling like you need to stay busy so you don't have to think
Using work, exercise, alcohol, or distraction to keep difficult thoughts away
You might recognize some of these.
Or maybe you don't.
Sometimes first responder PTSD doesn't look like falling apart.
Sometimes it looks like continuing to function while feeling increasingly exhausted by the effort.
“I’m Fine. I Just Need to Get Through This Week.”
First responders are often very good at getting through things.
That's part of what makes the work possible.
You deal with the call. You finish the shift. You go home. You get some sleep. You come back and do it again.
But repeatedly pushing difficult experiences aside doesn't necessarily mean your nervous system has processed them.
Sometimes the effects show up later.
Maybe you're more irritable at home.
Maybe your relationship has changed.
Maybe you're avoiding certain situations.
Maybe you're drinking more than you used to.
Maybe you're sleeping poorly.
Maybe you don't feel much of anything anymore.
Or maybe you're simply tired of feeling like you always have to be “on.”
First Responder Trauma Can Build Over Time
Trauma isn't always about one single event.
For police officers, firefighters, paramedics, dispatchers, corrections officers, and other emergency personnel, repeated exposure to traumatic situations can take a toll.
It can be one particularly difficult call.
It can be several calls.
It can be years of seeing things that most people never have to see.
Sometimes you can't identify one moment and say, “That's when everything changed.”
You just know that something has shifted.
Your Body May Still Be Responding to What Happened
One of the frustrating things about trauma is knowing intellectually that you're safe while your body continues to respond as though you're not.
You might tell yourself:
“I'm home.”
But your body says:
“Stay alert.”
You might tell yourself:
“It's over.”
But your mind keeps replaying it.
You might tell yourself:
“Nothing is happening right now.”
But your nervous system hasn't completely caught up.
This doesn't mean you're weak.
It doesn't mean you can't handle the job.
And it doesn't mean you're broken.
It means your nervous system learned something from what you experienced.
You Don't Have to Wait Until You Can't Function
You don't have to be having nightmares every night.
You don't have to be unable to work.
You don't have to be at a breaking point.
And you don't have to prove that your experience was “bad enough” to deserve help.
First responder trauma therapy isn't about taking away your ability to do your job.
It's about helping you have more control over your life when you're not working.
If trauma is affecting your sleep, relationships, ability to relax, mood, or connection with the people you care about, it may be worth paying attention to.
Learning How to Stand Down
Trauma therapy can help you understand what is happening and begin changing the patterns that keep your nervous system stuck in high alert.
I use Prolonged Exposure Therapy (PE) as my primary trauma treatment approach for PTSD, along with Acceptance and Commitment Therapy (ACT) and Cognitive Processing Therapy (CPT) when appropriate.
PE can help you gradually approach trauma-related memories, feelings, and situations that you've been avoiding, allowing your brain and body to learn that you can experience difficult things without being in danger right now.
The goal isn't to erase what happened.
It's not to make you forget the calls.
It's not to make you care less.
It's about helping the past take up less space in the present.
Because being off shift should eventually mean being off shift.
If you're a first responder in Hamilton or elsewhere in Ontario and you're noticing that the job is following you home, you don't have to figure it out alone.
Sometimes the hardest part isn't responding to the call.
It's learning how to stand down when the call is over.
