Prof Buteyko discovered in the 50s that people who develop chronic symptoms breathe more than the physiological optimal norm of 3-4 litres per minute. Martha Roe will show presentations by Senior Buteyko Practitioner Christopher Drake, to introduce Buteyko's research and approach to retrain breathing and reverse 200+ symptoms: asthma, allergies, ADHD, depression, eczema, migraine, insomnia, fatigue, diabetes etc. She will measure your breathing and host a Q&A session with Christopher via Skype.
