The Science

Why breathwork works

Breathwork is not a new idea. Cultures around the world have used conscious breathing practices for thousands of years. What is newer is the growing body of scientific research that helps us understand why it works — and what is actually happening in the body and brain when we breathe in particular ways.

The breath is unique among our bodily functions. It happens automatically, without us thinking about it — and yet we can also take conscious control of it at any moment. This makes it a remarkable bridge between the conscious and unconscious, between the voluntary and the involuntary, between the mind and the body.

The nervous system

Your breath & your nervous system

The autonomic nervous system governs our stress and relaxation responses. It has two main branches: the sympathetic nervous system (often called 'fight or flight') and the parasympathetic nervous system ('rest and digest'). Most of us spend far too much time in sympathetic activation — stressed, anxious, on high alert — without enough time in the parasympathetic state where healing, digestion and restoration happen. Conscious breathwork directly influences this system. Slow, extended exhales activate the vagus nerve and shifts us through these states. Through the continuous, connected breathing pattern of CCB, we temporarily change our CO₂ levels and blood pH. These physiological changes influence the brain and can shift our usual state of awareness, creating the conditions for an altered state of consciousness. This can allow us to experience thoughts, emotions, sensations and perceptions in a different way.  Another benefit is that it retrains our nervous system how to respond to any triggers that may happen throughout a session or workshop.

Trauma & the body

The body keeps the score

Trauma is not simply a memory of something that happened — it can leave lasting effects on the nervous system, influencing how we experience sensations, emotions, thoughts and our responses to stress. Research and clinical work, including that of Bessel van der Kolk, Peter Levine and others, has highlighted how traumatic experiences can continue to shape patterns of physiological arousal and defensive responses long after an event has passed. Talking therapies can be enormously helpful in making sense of our experiences, developing insight and creating new perspectives. But trauma can also involve processes that operate outside conscious awareness, including changes in autonomic arousal, body sensations and implicit emotional responses. These aren't always easily accessed through words alone. This is where breathwork and other somatic approaches can offer another pathway. By bringing conscious awareness to the breath and body, we can begin to notice and work with physiological patterns of stress and activation. With appropriate support and pacing, this may help us develop greater capacity for regulation, process difficult emotional experiences and cultivate a stronger sense of safety within the body.

Documented benefits

What the research shows

01

Reduced anxiety & stress

Research suggests that controlled breathing practices, particularly slow and diaphragmatic breathing, can reduce physiological arousal and may help reduce feelings of anxiety and stress.

02

Improved emotional regulation

Breathwork can influence autonomic arousal and may support our ability to respond to difficult emotions rather than becoming overwhelmed by them. It can also help create the physiological conditions that support more effective emotional regulation

03

Better sleep

Slow, calming breathing practices can help reduce physiological arousal before bed and may support relaxation, sleep onset and overall sleep quality.

04

Increased heart rate variability

Heart rate variability (HRV) reflects the variation in time between heartbeats and is influenced by autonomic nervous system activity. Slow, paced breathing can increase HRV during practice and may support greater flexibility in the nervous system.

05

Reduced chronic pain

Breathwork may help people manage chronic pain by influencing stress, autonomic arousal, attention and the way pain is perceived. It can be a useful complementary approach alongside appropriate medical or therapeutic care.

06

Enhanced self-awareness

Regular breathwork can develop interoception — our ability to notice and interpret signals from within the body. Greater awareness of these signals can help us recognise changes in emotion, stress and nervous-system activation earlier.
