During reduced breathing exercises it is vital that you create a hunger for air in order to bring about an accumulation of carbon dioxide in the blood. When this happens, the respiratory center in the brain is reset toward a calmer and more normal breathing volume. In order to reset the respiratory center by just a little, it is necessary to experience an air hunger for about 10 minutes. You can divide most of the exercises in this book into 2 sets of 5-minute sessions, or, if you feel you are confident and experienced in reduced breathing, you may practice for 10 minutes straight.
