Stay in the situation until anxiety drops
Remain in the feared situation long enough for distress to fall — leaving early teaches the wrong lesson.
Key takeaways
- What it is: Remain in the feared situation long enough for distress to fall — leaving early teaches the wrong lesson.
- Why it works: Within-session habituation occurs when the nervous system’s initial threat alarm is not confirmed by actual harm and attention to the physical sensation wanes. Leaving while still anxious reinforces escape as the relief strategy and prevents the new learning "this is survivable." The stay teaches survival; the leave teaches escape.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Leaving just as distress peaks because it feels unbearable — this is also the moment the learning could happen, and leaving cements the belief that escape is the only relief.
Why it works
Within-session habituation occurs when the nervous system’s initial threat alarm is not confirmed by actual harm and attention to the physical sensation wanes. Leaving while still anxious reinforces escape as the relief strategy and prevents the new learning "this is survivable." The stay teaches survival; the leave teaches escape.
How to do it
- 1Enter the situation at your current step with the intention of staying until your SUDs drop at least 50% from their peak.
- 2Do not use subtle avoidance — phone, distraction, or safety behaviors that reduce contact with the trigger.
- 3Rate your distress every few minutes; witnessing the decline is itself therapeutic.
- 4Exit only after the reduction, not before.
What the evidence says
RCT / meta-analysisWithin-session habituation is a well-documented phenomenon; the inhibitory learning model (Craske et al.) additionally emphasizes that violating the expectation of harm drives the learning even more than raw habituation.
Honest caveat: Newer inhibitory learning models question whether waiting for full habituation is strictly necessary — expectancy violation may be the core driver — but staying in the situation remains essential under either model.

Common mistake
Leaving just as distress peaks because it feels unbearable — this is also the moment the learning could happen, and leaving cements the belief that escape is the only relief.
