Trauma and Nervous System Exercises




Masha's Toolbox of Trauma Exercises is one of my favourite resources for tools to support and calm our nervous system in times of struggle.





Slowly | softly breathing: Regulating the nervous system through breath

When you feel your nervous system is struggling and you feel immobilised (freeze) or in fight/flight this practice of Slowly | Softly breathing can be helpful to regulate the nervous system:

A. Place your feet on the floor, hands on your legs or one hand on your heart and one on your belly.

B. Push your feet onto the floor and gently close or haze your eyes

C. Breathe in Slowly through your nose and out Softly through your nose (Slowly in | Softly Out)

D. Repeat and lengthen the breath each time in and out.


A guided audio version can be found here Breathing Room Voice Led Breath Exercise (7 minutes). The inhale is our sympathetic and exhale our parasympathetic nervous system. Slowing each brings calm to our body and nervous system. After a few breaths check-in:


  • Where is the tension/anxiety (contraction) in your body, and what is the feeling - use a feelings wheel to help and my Exploring Feeling & Emotions blog post.

  • Breathe into that part of your body and create release/expansion to the bodily contraction and acceptance of the emotional state

  • Ask yourself:

  • (a) what you do I need? (e.g. take a walk to feel grounded, reach out to someone... etc)

  • (b) externalise wherever possible by either talking with someone or writing out what is troubling

Self-holding exercise

1. Either seated or laying down with feet resting on floor. One hand on your heart and one on your belly. Push your feet onto the floor and gently rest your eyes.


2. Slowly/ Softly Breathing: Breathe in slowly through your nose. Breathe out softly through your nose. Aim to lengthen the breath each time in and out as you breathe three times.

3. As in the diagram place your hands on either side of your head (expansion). Now breathe in slowly and out softly into that space 'between' three times.


4. Place your hands on the front and back of your head. Now breathe in slowly and out softly into that space 'between' three times.


5. Move the hand on the back of your head to your heart. Now breathe in slowly and out softly into that space 'between' three times.


6. Move the hand on the front of your head to your belly. Now breathe in slowly and out softly into that space 'between' three times.

7. Move the hands on your heart to the back of your head. Now breathe in slowly and out softly into that space 'between' three times.


8. Finally, move the other hand to the back of your head as though you have wings and feel the expansion. Now breathe in slowly and out softly into that space 'between' three times.


9. Gently as you rest your hands beside you connect with your natural breath and the space around you.

In addition to Arielle Schwartz's brilliant Post Traumatic Growth Guidebook and Oprah and Dr Perry What Happened To You mentioned above these are helpful books:
