How I Help

Breathe Better

I look at how you're breathing throughout the day and while you sleep, then help you retrain unhelpful breathing patterns using gentle, functional breathing techniques.

Sleep Deeper

We look beyond bedtime, at breathing, stress and the everyday patterns that may be making it harder for your body to switch off and rest.

Stress Less

Simple, practical tools including breathing, restorative yoga and Yoga Nidra help you create pockets of calm and recovery in everyday life.

What Women Are Saying


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. - Sharon

Meet Ash

I'm Ash Whittle, a Functional Breathing Practitioner specialising in sleep, stress management and women's health through perimenopause and menopause.

For more than 25 years I've been helping people feel better through movement, breathing and practical health education.

I also know what it's like to be constantly busy, running on adrenaline and exhausted but unable to properly switch off. That experience changed the direction of my work.

Today I combine the Buteyko Method, functional breathing, sleep support, stress management, restorative yoga and Yoga Nidra, with a particular focus on supporting women through perimenopause and menopause, when changes in sleep, stress and how you feel day-to-day can become harder to manage.

My approach is practical and grounded in evidence, no complicated routines, just simple tools designed for real people and 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
