Breathing retraining has transformed my health.
The symptoms of asthma are gone and I no longer need to use inhalers.
The sleep apnoea and snoring is much reduced.
I've experienced other improvements in aspects of health which I attribute to being able to change my whole style of breathing.
I would heartily recommend the Buteyko Course, as taught by Glenn, to anyone wanting a change from chronic asthma, dependence on inhalers, and fatigue resulting from poor sleep.
