“The book is a self-help guide on self-medication and is intended primarily for seriously ill people. For those who are desperate to find health, for those who are tired of endless wanderings in hospitals and clinics, for those who have decided to put an end to their painful condition once and for all, to show will and love for life. We will talk about the most powerful means of positive impact on the body, which is how strong, but also harmless. I would never have written this book if for many years of medical practice (and an even longer period of my own studies) I had not been convinced of the highest effectiveness of Hypoxic Respiratory Training in the treatment of respiratory diseases, obesity, heart and vascular diseases, as well as in the complex measures aimed at rejuvenating the body.” Bulanov Yu.B.
