Key facts
What is the Fight, Flight, Freeze: Your Alarm System?
The fight-flight-freeze response, sometimes called the defence cascade, is the body’s automatic reaction to perceived threat. Explaining the purpose of each symptom, from racing heart to tingling to feeling unreal, is a standard first step in CBT for anxiety and panic because it reduces fear of the symptoms themselves.
Why it works
Psychoeducation about the purpose and harmlessness of anxiety symptoms is a core component of evidence-based treatments for panic disorder and anxiety (Craske & Barlow, 2006). Understanding the defence cascade, including freeze and shutdown, also helps trauma survivors make sense of their reactions (Kozlowska et al., 2015).
When to use it
- First sessions of anxiety or panic treatment
- Health anxiety about physical symptoms
- Trauma psychoeducation
- Teens and adults new to therapy
How to use it in session
- Use the smoke-detector metaphor to introduce the alarm system.
- Go through each body change and ask which the client notices.
- Normalize freeze responses, which are often misunderstood.
- Help the client write a short coping statement.
- Follow with breathing, grounding or exposure work.
Clinician tips
- Encourage clients to reread the handout during anxiety.
- Ask clients to check unexplained physical symptoms with their doctor once, then use the handout.
- Link to interoceptive exposure for panic.

Frequently asked questions
Can a panic attack cause a heart attack?
Panic symptoms are not dangerous for a healthy heart, though it is reasonable to have new chest symptoms checked by a doctor once.
Why do some people freeze instead of fight or flee?
Freezing is an automatic survival response, not a choice. It’s common in overwhelming situations and nothing to be ashamed of.
