9D Breathwork for Perimenopause - What your Nervous System actually needs
Published by Kora Wellness | Port Kembla, NSW | Serving the Illawarra region including Wollongong, Shellharbour, Thirroul, and Warilla.
It started with the 3am waking. Not anxiety about anything specific, there was no particular worry keeping me up, just a racing heart and heat moving through my chest and the complete lack of ability to do anything about it.
Then my mornings that I was already struggling with became more difficult: my patience was thinner than it should have been, I had tears close to the surface at odd moments and a kind of internal fizzing that didn't translate into anything I could point to or explain.
My GP said my hormones were changing and it was probably just stress - which was true. But it didn't quite account for why my body felt like it had started running on a different frequency and why when I removed the stresss, it still kept happening.
Perimenopause is framed, almost universally, as a hormonal event. And it is, but that framing accounts for only part of what's actually happening. When oestrogen begins to fluctuate and then decline, it doesn't only affect the reproductive system. It affects the autonomic nervous system directly.
Oestrogen supports vagal tone which is the functional strength of the vagus nerve, AND which is the body's primary driver of parasympathetic (calming) activity. As oestrogen shifts, your vagal tone impairs with it.
The nerve that regulates heart rate, temperature, digestion, sleep and emotional reactivity becomes less efficient. This is why hot flushes feel like panic, why sleep doesn't hold and why irritability arrives without cause and takes longer to leave.
Understanding this matters because it changes what you do about it.
Working on the nervous system (directly and consistently) has a point of entry into the perimenopause experience that hormonal treatment alone doesn't reach. 9D breathwork, specifically the downregulating kind, is one of the most direct tools for this. But the type of breathwork matters, and so does the sequence. What works well at month three of a consistent practice is not what the nervous system needs in week one.
Kora Wellness runs downregulating and activating 9D breathwork sessions across the week - Tuesday, Wednesday and Friday evenings, and Thursday and Saturday mornings. Book a session in Port Kembla here.
Why perimenopause is a nervous system event, not just a hormonal one
Think of the vagus nerve as the body's brake pedal; the thing that tells your heart to slow down after a scare, your breath to settle after a rush or your muscles to stop holding quite so much.
Oestrogen, it turns out, helps keep that brake working properly. As oestrogen begins to decline during perimenopause, the braking capacity slips with it.
The vagus nerve becomes less effective, which means the parasympathetic nervous system (the branch responsible for rest, digestion and recovery) can't activate as efficiently and your cortisol stays elevated longer than it should. And elevated cortisol, as a 2024 PubMed study documented, suppresses oestrogen and progesterone production further. The two systems don't just run in parallel, they actively affect each other.
What this means practically is that the hot flush arriving without warning isn't solely about oestrogen. It shares its mechanism with the 3am heart racing, the shortened fuse, the easily disrupted sleep - all of them products of the same nervous system running less efficiently than it should. A practice that addresses that directly can reach all of them from the same starting point.
A PMC systematic review of mind-body practices and menopausal symptoms found that six out of seven randomised controlled trials showed significant reductions across vasomotor symptoms, sleep disruption and psychological distress. Practices that work through the nervous system directly (not around it) produce measurable change in the hormonal transition experience.
When hormones shift, the nervous system shifts with them — breathwork trains the pathway back.
What downregulating breathwork does that nothing else does
Heart rate variability - the slight variation in timing between each heartbeat - is one of the most reliable measures of how well your nervous system can shift between states.
High HRV means the system moves fluidly: alert when it needs to be, settled when the moment passes. Low HRV means it's stuck in one gear, which shows up as anxiety that won't lift, sleep that won't hold and a hair-trigger response to things that shouldn't land that hard.
During perimenopause, HRV commonly drops and it responds to training in the same way fitness does, getting stronger with consistent practice.
A narrative review published in PMC in 2024 traced exactly how: each controlled exhale creates a small pressure shift in the chest that mechanically stimulates the vagus nerve. Not through medication, not through meditation - through the breath itself. That stimulation is what drives the change in vagal tone, which is what improves HRV over time.
In a downregulating 9D session at Kora, the breathing is nasal throughout - slow, with the exhale deliberately longer than the inhale. The 9D audio layers in low-frequency sound and binaural beats calibrated to support deceleration.
The session doesn't reach for an emotional peak or a cathartic release. It builds a steadier baseline; which for a nervous system running hotter than it should during perimenopause is exactly the point. Over consistent attendance, this is what shifts HRV. This is what builds the gap before a hot flush tips into full-blown panic, or a moment of irritability lands before there's any space around it.
When activating breathwork fits in - and when it doesn't
For women in perimenopause dealing with anxiety, heart palpitations, or broken sleep, activating breathwork is not where to begin.
The issue isn't that it can't eventually be useful - it can - but a nervous system that's already running in high gear doesn't have the settled foundation that circular breathing needs to do its job. Starting there risks adding more charge to a system that needs less of it, not more. The better sequence is to begin with downregulating sessions, build some steadiness and introduce activating work once the body has somewhere to return to after the intensity.
Activating breathwork is contraindicated entirely for anyone with cardiovascular disease, preganancy, bipolar or epilepsy. These apply regardless of perimenopause status.
For most women in perimenopause without those contraindications, the pathway is straightforward: start with downregulating sessions, let the nervous system build a calmer baseline over several weeks and introduce activating work from there. At that point, the difference between activating and downregulating sessions becomes something you feel rather than something you're told - the circular breath produces a release rather than more activation.
Hayley is happy to talk through where to start before your first session if you're not sure which is right for where you are right now.
What consistent practice actually changes during hormonal transition
Balban and colleagues, writing in Cell Reports Medicine in 2023, tracked how the body carries tension (and how that changes) across 28 days of daily structured breathwork. The gains were cumulative: mood improved, the body's stress response reduced and neither effect levelled off within the study period - what was happening in week four wasn't the same as week one, because the nervous system was still adapting, still building capacity.
For women in perimenopause specifically, what shifts with consistent practice is how much the nervous system can hold before it tips. A hot flush arrives but it doesn't immediately cascade into a racing heart and full panic. Waking at 3am still happens, but the return to sleep comes faster. The irritability that used to surface without any clear cause has more space around it. This isn't a dramatic transformation, it's a quieter, more durable shift in what the hormonal transition is moving through.
None of this stops the hormonal transition and it's not meant to. It changes what the nervous system can hold while it's happening. How often you practise for nervous system change is explored in more detail in our frequency post. The short answer during perimenopause is that two to three sessions per week tends to produce noticeably faster change than once a week alone, particularly in the first two months.
This is also why breathwork works alongside medical treatment rather than instead of it. Whether you're on HRT, considering it, or managing the transition through other means, the nervous system dimension of perimenopause responds to direct training, and, that training compounds.
Starting breathwork during perimenopause - what to expect at Kora Wellness
Kora Wellness is at 43 Wentworth Street in Port Kembla - a short drive from Wollongong, Shellharbour and Warilla, and accessible from Thirroul and across the Illawarra. Sessions run in groups, so you're attending alongside other people going through their own versions of the same work.
The room is dark, you're on a mat and the audio comes through headphones calibrated for the breathwork layering. There's nothing to perform, no worry that someone is watching or judging you, and nothing to get right.
New clientscan access Kora's introductory offer of 3 sessions for $99, which appears automatically in the Mind Body booking flow. Tuesday, Wednesday and Friday evenings, and Thursday and Saturday mornings - five session windows a week, which gives you flexibility if two or three sessions per week is the goal.
For most women in perimenopause, Hayley recommends starting with a downregulating session - nasal breathing throughout, no circular breath pattern, no cardiovascular demand. It's a gentler entry point, but its physiological benefit is distinct and real: it begins the process of improving vagal tone from the first session. If you're unsure whether you have contraindications for activating breathwork, that's a conversation worth having with Hayley before you attend.
If you're dealing with anxiety or sleep disruption specifically, how breathwork works on anxiety and the sleep and hormonal cycle connection are both explored in more detail on the blog.
Frequently Asked Questions
Can breathwork help with perimenopause symptoms?
Yes. Downregulating breathwork - slow nasal breathing with an extended exhale - directly targets the autonomic nervous system, which is significantly affected during perimenopause. As oestrogen declines, vagal tone impairs, raising baseline cortisol and contributing to hot flushes, sleep disruption, anxiety and mood instability.
Controlled nasal breathing stimulates the vagus nerve, increases heart rate variability and trains parasympathetic capacity. A PMC systematic review of mind-body practices and menopausal symptoms found significant reductions in vasomotor symptoms, sleep disruption and psychological distress across the majority of randomised controlled trials.
Is breathwork safe during perimenopause?
Yes, downregulating breathwork using nasal breathing is appropriate for most women in perimenopause. Activating breathwork - continuous circular mouth breathing - is contraindicated for anyone with cardiovascular disease, bipoloar, pregnancy or epilepsy.
Women with significant heart palpitations, which are common during perimenopause, should begin with downregulating sessions only. If you have a pre-existing cardiac condition or cardiovascular risk factors, consult your GP before attending any breathwork session.
Can breathing exercises help with hot flushes?
Yes. Hot flushes are partly a vasomotor response produced by autonomic nervous system dysregulation - the same system that controlled breathing directly targets. Slow nasal breathing activates the parasympathetic branch, reducing the sympathetic arousal that triggers vasomotor events.
Studies on paced breathing at approximately six breaths per minute have documented reductions in hot flush frequency and intensity. Consistent practice over weeks produces more durable change than using breathing reactively in the moment, because it addresses the underlying vagal tone deficit rather than the individual episode.
What type of breathing is best for menopause anxiety?
Downregulating breathwork - slow nasal breathing with an extended exhale - is the most appropriate starting point for menopause-related anxiety. The longer exhale preferentially stimulates vagal activity, activating the parasympathetic nervous system and reducing cortisol.
For women with significant anxiety during perimenopause, activating breathwork (circular mouth breathing) should be avoided until a more stable nervous system baseline is established, as it can amplify arousal in a system that is already running reactively.
Does breathwork help with menopause sleep problems?
Breathwork addresses perimenopause sleep disruption through two pathways. In the short term, downregulating sessions reduce cortisol and physiological arousal, supporting sleep onset.
Over consistent practice, the training effect on heart rate variability and vagal tone expands the nervous system's capacity to remain in parasympathetic dominance through the night. The 3am waking pattern common in perimenopause, often accompanied by heart racing and heat, responds to nervous system training, not only in-session calming.
Can perimenopause cause breathing difficulties?
Perimenopause can produce symptoms that affect the breath, including shortness of breath, heart palpitations and heightened awareness of the breathing pattern. These are typically autonomic in origin, the same decline in vagal tone that produces hot flushes and anxiety can cause dysrhythmia in heart-breath coordination. Breathwork does not cause these symptoms.
For most women, learning to direct the breath is stabilising rather than anxiety-provoking, particularly in the downregulating format where the breathing pattern is slow and nasal throughout.
How often should I do breathwork during perimenopause?
For nervous system change during perimenopause, two to three sessions per week produces faster and more durable results than once weekly. Downregulating sessions are appropriate at this frequency from the outset. Activating sessions, once introduced, are typically added one per week alongside downregulating sessions.
Frequency should be calibrated to what the nervous system can integrate - post-session fatigue is normal and part of the adaptation process, but ongoing exhaustion indicates the pace needs adjusting.
Is 9D breathwork safe if I have heart palpitations?
Heart palpitations during perimenopause are typically vagally mediated - a symptom of autonomic dysregulation rather than structural cardiac disease.
Downregulating 9D breathwork using nasal breathing is generally appropriate and, with consistent practice, tends to reduce palpitation frequency by improving vagal tone.
Activating 9D breathwork using circular mouth breathing should not be undertaken without GP clearance if palpitations are significant or frequent.
If you have a diagnosed arrhythmia, cardiac condition, or are on heart medication, consult your GP before attending any breathwork session.
What is the vagus nerve and why does it matter in menopause?
The vagus nerve is the longest nerve in the autonomic nervous system, running from the brainstem through the heart, lungs and digestive tract. It is the primary driver of the parasympathetic response of rest, digestion, recovery, emotional regulation.
Oestrogen supports vagal tone, which is the functional strength of vagal activity. As oestrogen declines during perimenopause, vagal tone impairs. Reduced vagal tone means reduced capacity to regulate heart rate, temperature, sleep, digestion and emotional reactivity - which is the mechanistic basis for many of perimenopause's most disruptive symptoms.
Can I do activating breathwork during perimenopause?
Activating breathwork using continuous circular mouth breathing is not an appropriate starting point for women in perimenopause experiencing high anxiety, significant heart palpitations, or severe sleep disruption.
It is contraindicated for anyone with cardiovascular disease, pregnancy, bipolar or epilepsy. Women in perimenopause without these contraindications can typically introduce activating breathwork once a baseline of nervous system regulation has been established through consistent downregulating sessions, usually after several weeks of regular attendance.
