Sleep, Hormones & Nervous System Reset
(Perth & Online)
A personalised 90-day reset for women navigating perimenopause & menopause
Does this sound like you?
• Waking at 3am
Brain fog
Not yourself
Snapping
Hot flushes
Exhausted but can't switch off
This isn't just "in your head."
It's your nervous system stuck in overdrive.
When your breathing is fast, shallow or through the mouth, your body stays in a stress response, which affects sleep, hormones and how you feel day to day.
Over 90 days, we gently reset your breathing, nervous system and sleep patterns using simple, science-based tools that fit into real life.
What this reset supports:
✔ Deeper, more consistent sleep
✔ Calmer evenings and mornings
✔ Better hormone regulation
✔ A steadier nervous system
✔ Feeling grounded in your body again
This is not breathwork hype or quick fixes.
It’s personalised, evidence-based support, guided by someone who understands both the science and this season of life.

Meet Ash
I'm Ash Whittle, a Functional Breathing Practitioner, Sleep Coach and Yoga Therapist based in Perth.
I help women who are tired, wired, waking at 3am and struggling to switch off.
The work I do today comes from personal experience.
For years I lived completely on adrenaline. Always on. Always thinking. Always pushing through.
From the outside everything looked fine, but inside I felt overwhelmed, exhausted and like my system had forgotten how to properly rest. Sleep wasn't restoring me. My mind never seemed to slow down.
I know how it feels to be holding everything together while quietly running on empty.
That's why I'm passionate about helping women calm an overworked nervous system, improve sleep and feel like themselves again.
My approach combines functional breathing, sleep support, restorative yoga and nervous system regulation using practical tools that fit into real life.

Testimonial
I have been working with Ash of O2.4.U for months now and have enjoyed numerous benefits of her Science based approach to optimising health using breathwork and other means. All of the methods that we work on are practical, simple and easy to implement. It never feels like 'another thing to do' - rather a more mindful, effective way of doing what we all do all day (and night) long. It is fantastic to learn so much and empowering to know that there are multiple tools at my fingertips - or nostrils!
Most recently, Ash spent time preparing my racing partner and I for an endurance event. Her fantastic range of techniques for regulation, increased focus, greater endurance and improved performance were all greatly appreciated on race day! I have loved tapping into Ash's beautiful energy, great expertise and constant encouragement so far. - Sharon
