Conscious Connected Breathing or Conscious Connected Circular Breathing is basically carried out just like Circular Breathing, but then done deliberately without any pause between inhaling and exhaling. As such, it explicitly links inhalation and exhalation in a continuous, rhythmic cycle.
It can be practiced with or without sounds, that is, with or without making a noise when breathing out. Moreover, it can be done by inhaling through the nose and exhaling through the mouth, or only using the nose or only using the mouth, or by using both the nose and mouth at the same time, depending on the type of Breathwork modality that’s applied.
Typically, the idea is to start slowly (just like doing normal Circular Breathing) but then gradually speed up Circular Breathing during a session, which means that it also becomes rapid breathing, but still with applying full inhales and exhales.
In several Breathwork modalities, notably those that fall in the group of Transformational Breathwork, Conscious Connected Breathing is frequently used as a technique to increase self-awareness and to induce a kind of controlled hyperventilation in order access and release repressed or bottled-up emotions and trauma.
It’s also thought that Conscious Connected Breathing cleanses the pranic or energetic body, makes Life Energy flow freely, and allows us to access expanded, altered, non-ordinary i.e. psychedelic states of consciousness.
