My smoke detector

Recognising the false alarms of my protection system

Brain, stress and coping · worksheet 133

Your alarm system works like a smoke detector: it would rather go off for burnt toast than miss a real fire. That was useful for survival, but it produces many false alarms. Recognising them helps you judge yourself less.

Before you start

  • What it is for: To understand that your anxiety isn’t a fault: it is a protection system set to be cautious, which often aims at the wrong target.
  • A few minutes after each alarm, for a week.
  • Fill it in when you are calmer, not in the middle of the alarm.
  • A false alarm isn’t silly: your body was trying to protect you.

What to do with your results

If many alarms have low real danger, they are good targets to work on with your psychologist.

If you find it hard

If you are in real danger (violence, threats), your alarm is right: tell someone you trust or call 112.

For psychologists

The PDF also includes a page for the psychologist: how to run the exercise in session, points to watch and scientific references. You are free to use it with your clients.

For psychologists: aim, audience and duration
Explain the “smoke detector principle” (Nesse) and help the person distinguish true alarms from false ones, without blaming themselves for their reactions.
Anxiety, panic attacks, hypervigilance, people who judge themselves “too sensitive”. Duration: 15-20 min, then to fill in over a week.
