Respiration is driven by the autonomic nervous system, and most of the time breathing occurs unconsciously. When stress levels rise, the sympathetic nervous system becomes active and one might tend to acquire a dysfunctional breathing pattern, like overbreathing. With breathing therapy a client can become aware of the breathing pattern and change dysfunctional breathing patterns to promote improved homeostatic and generative processes.
To measure respiration, we usually place a respiration sensor over the abdomen, as this is associated with relaxed breathing. With every breath, the sensor measures the relative expansion and contraction of the belly. Measure abdominal or thoracical breathing rate and relative depth of breathing.
