Medical Information, Suggestions
Hmmmmm - despite the fact that there is a thread of truth regarding the efficacy of this better breathing concept, the process itself seems curious, at least with respect to several techniques described in the book. Still - if it works for some its a good thing.

"Druid knowledge"
This book is a splendid example of a 'knowledge-giver.' The information is so easily formatted, and the words so simple, that anyone can read it and take in the advice as something second nature. After reading and applying the suggestions in this book, proper breathing during exercise, stress, and other circumstances can lead to an ease not experienced before. I am a cross trainer, and when I was young I couldn't breathe properly so everyone told me I had asthma. Asthma may exist as a medical problem, but its also a state of mind. The ability to control our bodies is underestimated. This book is nature in words.

It's a mini "Asthma Free Naturally"
"Close Your Mouth" is a more concise version of "Asthma-Free Naturally" also by Patrick McKeown, with much repeated information. There's less information in "Close Your Mouth", but it's easier to read, and has a better quality cover while still providing enough information to learn the Buteyko exercises.

Both books are highly recommended although I'd recommend buying one or the other, both aren't necessary. If you want more information get "Asthma-Free Naturally", if you're more interested in simply learning the exercises, "Close Your Mouth" will be enough.

A best seller in its own right
This book is bound to become a best seller. The information is superb. Easily legible, understandable and supported by over forty years of research. I recently viewed the trials of Buteyko breathing for asthma- these results should be made more available.

Read this book for your health. I guarantee that you will be satisfied by the message therein.

Absolute must for asthmatics
The Buteyko clinic handbook- ground breaking stuff. I would advise readers to do their research on Buteyko especially if they have breathing related problems. The site of the book is http://www.buteykoclinic.com/ - look at the history, conditions, and scientific evidence from the New Zealand Medical Journal and Australia Medical Journal. It is incredible that this approach has not being adopted into mainstream medication - maybe this will happen but will surely take time. You can take the first steps now- read this book
