Anxiety has a momentum to it. Once it starts building, it tends to build further — not because something is getting more dangerous, but because your nervous system is responding to its own signals.

Understanding why this happens is the first step to interrupting it.

What escalating anxiety feels like

  • A sense of dread that grows without a clear cause
  • Physical symptoms — racing heart, tight chest, shallow breathing
  • Thoughts that spiral or jump to worst-case scenarios
  • Difficulty concentrating or making decisions
  • Feeling like you need to do something but not knowing what

Why anxiety escalates

The anxiety cycle works like this: you notice a threat (real or perceived), your sympathetic nervous system activates, and your body prepares to respond. So far, this is normal and useful.

The problem is that the physical sensations of anxiety — racing heart, tension, shallow breathing — can themselves be interpreted as threatening. Your brain notices the symptoms and concludes something must be wrong, which intensifies the response.

Research by David Clark on cognitive models of anxiety shows this feedback loop is central to why anxiety escalates: you become anxious about feeling anxious.

What tends to make it worse

  • Trying to suppress or ignore anxious thoughts — which often rebounds
  • Avoiding situations that trigger anxiety (reduces it short-term, worsens it long-term)
  • Checking and reassurance-seeking, which maintains uncertainty rather than resolving it
  • Caffeine, poor sleep, and low blood sugar (all increase physiological arousal)
  • Ruminating on 'why do I feel this way' rather than what might help

How to interrupt the cycle

  • Slow your exhale — breathing out longer than you breathe in activates the parasympathetic system (try 4 counts in, 6 counts out)
  • Name what you are feeling — research by Matthew Lieberman shows that labelling emotion reduces amygdala activation
  • Ground yourself in the present — notice 5 things you can see, 4 you can touch, 3 you can hear
  • Move your body — even a short walk shifts the physiological state
  • Challenge the threat appraisal — ask: what is the actual evidence for the worst-case scenario?

What helps over time

Managing anxiety well over time is less about avoiding triggers and more about building tolerance — through gradual exposure, consistent sleep and exercise, and learning to observe anxious thoughts without treating them as facts.

If anxiety is frequent, intense, or significantly limiting your life, professional support — particularly cognitive behavioural therapy (CBT) or acceptance and commitment therapy (ACT) — has a strong evidence base.

A grounded next step

Next time you notice anxiety building, try the extended exhale before doing anything else. Breathe in for 4 counts, out for 6. Do it three times. This alone can begin to shift the physiological state before thoughts take over.
