Breatheolution is a nervous system–led coaching practice that uses controlled stressors—such as breath training, cold exposure and heat—to help people build real-world regulation, resilience and calm control. Over the past six years I’ve worked with nearly 4,000 people, guiding them through carefully dosed experiences that prioritise safety, consent and sustainable change. At Breatheolution, attention to detail is the difference: how we frame the experience, how we breathe, how we pace the exposure, and how we integrate afterwards. That precision helps shape the outcome for each individual—turning intensity into learning, and stress into adaptive regulation.

Extensive knowledge on a very serious topic. I highly recommend this work for anyone working in the field of open water swimming or contrast therapy.
I participated in a training day with Kev at Breatheolution recently - wow - what can I say!! His knowledge and experience and his delivery style kept the whole room captivated all day. Kevs passion for his subject is undeniable- if you are thinking of training with Kev press the button now.
I met Kevin during a BJJ and wellness camp, and his workshops are always engaging and genuinely beneficial. Focused on calming the nervous system, they offer practical tools you can apply straight away.
I never thought I’d be able to immerse myself in cold water, but thanks to his guidance, I’ve done it multiple times. Also, training while controlling breath (like taping the mouth during BJJ) was challenging and eye-opening.
Working with Kev helps you understand your body better and feel more in control of your breathing, mind, and reactions. Highly recommended for anyone interested in breathwork and cold water therapy.
Having attended the Trauma Informed Cold water therapy program I can honestly say it has given me a passion to help others in the safest way possible. Kevin's knowledge and understanding is second to none. Not only have I gained the tools he helped me immensely on reclaiming my confidence in starting to coach. Will always be thankful for the support given and will probably continue to give
I’ve worked with Kev on several occasions. Initially he helped me and my friends access Coldwater therapy during 1-1 sessions. We felt empowered and protected during the sessions and it really kickstarted my love for Coldwater therapy and Breathwork. A journey that has lasted for five years… Last year I was fortunate enough to attend facilitator training in York with Kev and a fantastic group. His passion for wellness, recovery and safety and sharing his knowledge in the area is unsurpassed. Forever thankful we connected and I love watching his journey continue. I would highly recommend to anyone. You are in good hands.
Kevin was my first introduction to breath work and cold water emersion. It was such a transformational event for me and set me off on a path i really had not banked on.
He was so knowledgable and the location was just unbelievable.
i now use breathwork to manage all kinds of situations and have daily practices to.
Kev is the best at what he does. Myself and my family have been working with Kev for 4 years and he always goes above and beyond. He has helped me so much with anxiety and introduced me to the amazing benefits of breathwork and Cold Water. I wouldn't trust my family with anyone else!
Wonderful man with so much knowledge of the central nervous system and how it regulates. Wonderful meditation and breathwork. Always a pleasure to be in the company of Kevin
First met Kev 3yrs ago. Cold water session for my birthday. Since then I’ve done Kev’s cold water instructor course and a one day breath work course with him. Kev is incredibly knowledgeable and a fantastic teacher. He’s also an amazing human. The world needs more people like Kev O’Neill. 🖖

I did one session of cold water immersion and breathwork. I had never done this before, and Kev made it a very positive experience. Kev was accommodating, patient, professional and an amazing human being. I highly recommend all sessions with Kev.

I completed my Cold Water Therapy Instructor training with Kev, and I honestly couldn’t have asked for a better teacher. His knowledge, experience, and passion for cold water therapy really shine through in the way he teaches. He has such a calm, supportive approach and explains everything in a way that is easy to understand while still going into great depth.
I felt incredibly well supported throughout the training, and he created a safe and encouraging environment to learn in. You can tell he genuinely cares about the practice and about the people he’s teaching, which makes such a difference.
I would highly recommend training with him to anyone interested in learning about the power of cold water in a safe and knowledgeable way.

Kev helped me at a time when I was in a really dark place and I’ll always be grateful for that. He’s incredibly knowledgeable but, more importantly, he genuinely cares about the people he works with.
The breathwork was incredibly powerful and made a huge shift in my mindset.
I later went on to do his cold water instructor course, which was packed with valuable information and taught by some great experts he brought in.
I’d highly recommend Kev to anyone looking to build mental resilience and improve their wellbeing.

Amazing knowledge and guidance with cold water therapy, meditation and breathwork. Kind, compassionate and accommodating. Really really helped me manage my head, heart and body through cancer treatment and beyond. I entered the session afraid of the water, now I embrace it and yearn for the reset of a cold plunge. I now sea swim too!

I went to Kevin twice. The first time, he supported me at the beginning of my breathwork journey, helping me understand its effect on the body and its deep connection to our emotions. It was a revelation, and that session became an important part of my healing journey.
I went back to Kevin when I felt ready to go deeper and knew I needed his empathy, insight and support. He held space for me with real care and asked thoughtful questions that prompting me to reflect in a way that was a catalyst to a shift in perspective.
I can genuinely say that Kevin has been instrumental in the early stages of coming back to myself.

Kev’s depth of knowledge is truly exceptional. His understanding of cold water immersion and breathwork is phenomenal, and he has a remarkable ability to guide you safely while helping you push beyond what you thought was possible.

Kev is a really great guy and I’m glad to have met him. He led my very first cold water immersion session down at Combs Reservoir. Before we entered the water he guided a breathwork session that really helped prepare my body and mind.
The water was very cold, but Kev held the space well and guided me through the experience calmly and confidently. I felt safe and trusted his guidance the whole time.
If you’re interested in cold water immersion, breathwork, or anything Kev is offering, I’d definitely recommend giving it a go. You’re in good hands.
