Renaud Cmela - Certified Wim Hof Method & Oxygen Advantage Instructor Like too many people, I used to suffer from anxiety and overuse of prescription drugs. I struggled psychologically and it would also make me physically sick. I managed to stop prescription drugs and tried to deal with my issues on my own, however I was often getting sick and would be on antibiotics. Too often. I got tired of it and found out about Wim Hof on YouTube and decided to try it. It changed me, boosted my immune system, focus, energy and it introduced me to the world of breathwork. I studied various breathing techniques such as yogic breathing or conscious breathing and also became an instructor in the Oxygen Advantage. I've since helped hundreds of people with various ailments, from anxiety to disease, snoring or sleep apnea to speech therapy through the breath. Breathing changed my life for the better and I strive to help people live better lives by making by making simple changes.
