Breathing is a unique function that lies at the interface between our conscious and subconscious behavior. It represents a bridge in the brain between the conscious and the subconscious. By controlling breathing, we can control our mental health, health, and performance. Breathing is essential for life, and the subtleties of how we breathe, the duration and intensity of our inhales and exhales, how long we hold our breath between inhales and exhales, very critically define our state of mind and our state of body. In particular, breathing is important for our ability to generate muscular effort, especially of a kind of endurance work, weight training, and other forms of skill-based effort, as well as our ability to think. Nasal breathing is better than mouth breathing, and getting good at nasal breathing is useful. By using our brain consciously to control our breathing, we are using our brain to control our brain.
