Dr Marc’s Professional Journey

I went into medicine interested in fulfillment, fun, and wellness. I soon discovered that in Western medicine, I’d be learning about illness and I took 4 years off my medical degree to study physiology, psychology, and do a PhD in Chinese Medicine before finishing my medical degree.


I did a further PhD in computer systems engineering and worked as a locum General Practitioner and in Emergency Departments. I saw that while Western medicine was good for acute conditions, it missed the mark with chronic disease.


I then discovered health retreats that offered lifestyle solutions such as yoga, meditation and organic vegetarian food and I learned about Dean Ornish and the mounting evidence that interventions that had you relax exercise, eat good food and share your feelings could reverse heart disease and unblock arteries.


Then in the mid-1990s I discovered spas and as my natural medicine interest developed, I co-wrote seminal textbooks on herbs and natural supplements and the global spa industry. Over the past 16 years as a Professor of Health Sciences I have researched acupuncture, organic food, herbal medicine, the Buteyko technique,, yoga, meditation,  pranayama and dysfunctional breathing, along with saunas, hot springs and the Wim Hof Method.


I always felt there were ‘natural cures’ beyond commercial solutions that could put people’s health back into their own hands. I now realise that by communicating with our cells in their own language – the language of water, glucose, oxygen, temperature and carbon dioxide –  it is possible to hack into our physiology and access our evolutionary potential for well being.


Extreme Wellness practices help to counter the forces of entropy, clear your channels of elimination and explore the edge of your comfort zone, while also experiencing profound relaxation and extreme comfort.

Dr Marc’s Personal Story

I’d already had multiple knee injuries and surgeries before I was literally hit by a bus. I was thrown from my motorbike and snapped my leg in half causing my toe to touch my knee. I was told I could lose my foot, and would find it hard to walk properly again.

After 9 months of plaster and rehab, I refused orthotics, and simply adapted to a slightly shorter left leg. As a doctor and expert in natural remedies I tried every natural treatment including herbal and nutritional remedies, osteopathy, chiropractic, acupuncture and yoga— they all helped marginally, and I continued to live an active outdoor life—including hiking to Everest Base Camp. Yet, as the years went by I found myself in more and more pain and when I hit my 50’s it began profoundly affecting my life. I began to limp and reduced my exercise and put on weight, and once my sleep was affected I really struggled to keep up with the demands of a busy life.

In 2016 I heard about the Wim Hof Method and began taking cold showers, then in early 2017 I met-up with Wim and began his breathing and ice bath practices in earnest. My musculoskeletal pain diminished, and my physical resilience and mental focus surged. I noticed some big changes. I no longer limped. I slept soundly, without physical pain. My appetite changed, and I became happy to eat one or two small meals a day. I no longer felt the effects of decades old injuries.

As I worked with Wim on the science behind the Wim Hof Method, I found my 30 years of study culminated in a deep understanding of how consciously manipulating the basic elements of life – oxygen, carbon dioxide, water, temperature and glucose – could hack into our evolutionary potential and transform our physiology.

Extreme Wellness was born—and I knew I had to share this with as many people as possible. This is now happening through the Bathe the World Foundation and World Bathing Day and the Extreme Wellness Retreat at Maruia will allow a select few immerse themselves in a range of experiences that will transform their world.
