Breathwork in London: what it actually is, why everyone from NASA to your neighbour is doing it, and where to go

British Vogue named breathwork one of its top wellness trends for 2025, featuring Rob Rea as a leading expert alongside some of London's most respected practitioners. NASA, Nike and Google have built it into their employee wellness programmes. And yet if you mention breathwork at a dinner party, someone will still look at you sideways and say, isn't that just breathing? 

Yes and no. We all breathe about 20,000 times a day without thinking about it. Breathwork is what happens when you make it intentional, and the physiological difference turns out to be considerable. The research is genuinely compelling, the techniques are simpler than most people expect, and the London practitioners working in this space are doing some of the most interesting work in wellness right now. 

Here is everything worth knowing. 

Why it works: the short version 

Breath is the only function of the autonomic nervous system that is both involuntary and fully under conscious control. Which means it is the fastest available lever for shifting your physiological state. The nervous system operates across two modes: sympathetic, which governs the fight-or-flight response and keeps the body on alert, and parasympathetic, which governs rest and recovery. Chronic stress, which most high-performing professionals are navigating to some degree, keeps the sympathetic system dominant and the parasympathetic system suppressed. Specific breathing patterns can change this directly, within minutes, sometimes within seconds. BBC Science Focus describes the effect clearly: controlled breathing regulates the vagus nerve, which is the primary communication pathway between the brain and body, slowing the heart rate, easing inflammation and shifting the body from high alert into genuine recovery. The science is robust. A meta-analysis published in Scientific Reports across 785 participants found that breathwork significantly reduced self-reported stress, anxiety and depressive symptoms compared to control conditions. 

The more interesting question is not whether breathwork works. It’s which technique to use, and for what. 

The techniques worth knowing

Not all breathwork is the same, and the differences matter. Here is a practical guide to what is actually out there. 

Box breathing is the one most people have heard of, and for good reason. Four counts in, four counts hold, four counts out, four counts hold. Repeat four times. It activates the parasympathetic nervous system reliably and quickly, which is why it is used in surgical theatres and by special forces. Four minutes is genuinely enough to feel a measurable shift. It is the technique to reach for before a difficult meeting, after a stressful call, or at the end of a day when the body is still running at full speed but needs to come down. 

The physiological sigh, which Stanford neuroscientist Andrew Huberman has written about extensively, is the fastest known method for real-time nervous system downregulation. A double inhale through the nose, the second one short and sharp, followed by a long slow exhale through the mouth. Two or three repetitions. It works because the extended exhale activates the parasympathetic response, and the double inhale fully inflates the lungs' air sacs, which tend to collapse under sustained stress. The body does this naturally when you cry. Doing it deliberately produces the same effect on demand. 

Conscious connected breathwork is the foundation of most facilitated sessions. A continuous circular breath, inhaling and exhaling without pause, usually accompanied by music, and held in a group or one-to-one setting with a trained facilitator. This is where things get more significant. Sessions typically last between 45 minutes and two hours and can produce states of emotional release, clarity and, for some people, something closer to a genuine altered state of consciousness. Research from Brighton and Sussex Medical School published in 2025 found that this kind of breathwork produced changes in blood flow to the brain regions associated with emotional memory processing, and reliably reduced fear and negative emotions across participants. It is not a casual thing. It is also not something to be anxious about, provided the facilitator is properly trained. 

Holotropic breathwork is the deepest end of the spectrum, developed by psychiatrist Stanislav Grof and involving extended sessions of accelerated breathing with music in a carefully supported setting. It is not for everyone and is not where most people start. But for those who have been drawn to it, often after other approaches have reached their limits, it can be genuinely transformative. 

Who is doing this seriously in London 

Rob Rea is the name that comes up most consistently at the premium end of the London breathwork scene, and his credentials are solid. Featured in Vogue, The Times, Tatler and Elle UK, he runs monthly workshops at OMNOM in Islington as well as one-to-one coaching, retreats and corporate programmes. His approach is grounded in human performance science and works particularly well for high-achieving individuals who want the nervous system benefits without the more esoteric framing that can make breathwork feel inaccessible. He has a retreat at Cabilla Cornwall in May 2026 and his work is worth experiencing in person if you have the chance. Find him at robrea.co.uk. 

Arise Breathwork runs group sessions, online breath circles and workshops across London and Bristol, with a warm community feel and accessible entry points for those coming to breathwork for the first time. Founded by Brenna, it has built a genuinely loyal following and is a good starting point if you want to experience conscious connected breathwork in a well-held group setting before committing to anything longer. 

For those drawn to the deeper holotropic work, Basia Zieniewicz facilitates sessions in East London through Yoga in the Stars in Leytonstone. Her background is extensive, her facilitation is meticulous, and the sessions are three hours in a properly supported environment. This is the one to consider if you are at a point where you want to go inward rather than simply regulate. 

Why the corporate world has caught up 

The detail that tends to change the conversation, particularly for anyone who has dismissed breathwork as the preserve of yoga retreats, is this: NASA, Nike and Google have all built breathwork into their employee wellness programmes. Not as a nice-to-have addition but as a recognised tool for managing the nervous system under sustained pressure. The reason is straightforward. Breathwork is free, fast, portable, requires no equipment and produces measurable physiological results. For organisations running people at high intensity, it is a practical intervention rather than a wellness gesture. 

This shift reflects a broader recognition that the most effective wellbeing tools are not always the most complicated ones. The breath is the most direct lever available to the nervous system, and learning to use it deliberately produces results that most high performers, once they have experienced them, do not want to give up. For more on the nervous system and how sustained stress affects high-performing professionals specifically, see our pieces on burnout in high performers and the mental load nobody talks about. 

Where to start if you are new to this 

Try box breathing tonight before you go to sleep. Four minutes, four rounds. If it does nothing, you have lost four minutes. If it shifts something, you will know why this has become one of the most widely adopted performance tools of the last decade. 

If you want to go further, Rob Rea's monthly London workshops are the most accessible high-quality entry point in the city. Arise Breathwork is excellent for those who want a more community-based experience. And if you are looking for something more intensive, whether for yourself or for a team, Ten Ahead can help you find and coordinate the right practitioner and setting for what you actually need. 

That, ultimately, is the point. Breathwork is not a trend in the way that wellness trends tend to come and go. It is a tool, backed by a growing body of research, that works when you use it. The only question is whether you find the version that is right for you.
