Breathwork for Trauma: How Conscious Breathing Rewires the Nervous System

By Nisarga Eryk Dobosz · 6 July 2026

Trauma doesn’t just live in our memories. It echoes in our bodies, tightening muscles, quickening the breath and keeping the nervous system on high alert. But what if the key to loosening this grip was as close as your next inhale? Breathwork is a powerful somatic tool that doesn’t just calm the mind, it supports the nervous system at its core. Through conscious breathing we can shift from survival mode towards safety, release stored tension and reclaim vitality. Let’s explore the science behind it, with a spotlight on Biodynamic Breathwork (BBTRS®), a holistic approach I have seen change many lives, and simple ways anyone can start today.

How trauma affects the nervous system

At the heart of this is your autonomic nervous system, the body’s autopilot for stress and relaxation. It has two main branches: the sympathetic (“fight or flight”), which ramps up during threat with a racing heart and shallow breath, and the parasympathetic (“rest and digest”), which supports calm, recovery and connection. Trauma often keeps us stuck in sympathetic overdrive, which can show up as anxiety, poor sleep or numbness.

Research suggests breathwork can flip this switch. Slow, intentional breathing stimulates the vagus nerve, your “wandering” calm conductor, and increases parasympathetic activity. A 2023 meta-analysis in Scientific Reports (Nature Portfolio) found that breathwork reduces stress and improves mental well-being, and studies link it to lower cortisol and higher heart rate variability (HRV), a measure of nervous system flexibility.

What research says about breathwork and trauma

For trauma specifically, breathwork shines. Stanford research (2022) found that a simple daily breathing practice compared well with other approaches for easing post-traumatic stress symptoms. Why? Conscious breathing creates “safety cues” that tell the brain: the threat is over. This can quieten the amygdala, the brain’s fear centre, and strengthen the prefrontal connections that help us regulate emotion. Reviews in Neuroscience & Biobehavioral Reviews also describe how higher-ventilation breathwork can support a felt sense of release.

Biodynamic Breathwork and Trauma Release System (BBTRS®)

BBTRS® is the somatic, trauma-informed method I practise and teach. Developed by Giten Tonkov, it combines breath with movement, sound, touch, emotional expression and meditation to gently “charge” the nervous system. Unlike forceful techniques, it honours your body’s pace and supports the release of chronic tension without overwhelm. Deep connected breathing reaches the physical imprints of trauma, like frozen fear in the chest or anger in the belly, and then allows a safe discharge of held energy into a calm, parasympathetic state. Participants often describe deep shifts: from dissociation to presence, from numbness to aliveness. You can learn the method yourself in our BBTRS® training in Estonia.

4 simple breathing practices to start today

The beauty is that you don’t need a session to start. Your breath is always with you. Practise in a safe space and start slowly, 5–10 minutes. If strong emotions arise, pause and ground yourself, for example by feeling your feet on the floor.

• Diaphragmatic (belly) breathing. Lie down with a hand on your belly. Inhale through the nose for 4 counts so the belly rises, and exhale slowly for 6. The longer exhale encourages the parasympathetic response and signals safety, and it gently massages the organs where fear is often held.
• Cyclic sighing. Inhale deeply through the nose, pause, then add a second, shorter inhale. Exhale fully with a sigh. Repeat 5–10 times. This supports HRV and helps the body move from freeze towards flow.
• Connected breathing (BBTRS®-inspired). Breathe continuously without pauses, in through the nose and out through the mouth, like a circle. Add gentle movement such as rocking the hips. This charges the system and supports the release of stuck energy.
• 4-7-8 breath. Inhale for 4, hold for 7, exhale for 8 with a soft “whoosh”. Repeat 4 rounds to invite a quick shift towards calm and interrupt hypervigilance.

Breath as your birthright

These aren’t magic fixes, they are invitations to presence. Breath tells your nervous system: you are safe now. Over time it rebuilds trust in your body and loosens trauma’s grip. Combine it with nature walks or journaling for deeper integration.

Breath is your birthright, free and potent. In this dance of inhale and exhale you are not only rewiring nerves, but turning your whole being towards freedom.
