For the first time ever, a system exists where meditative breathing may be paced along with an audio-visual entrainment (AVE) session. Long, graceful breathing cycles have been used as part of meditation. Scientifically, this technique has been analyzed and shown to settle down a stressed autonomic nervous system. Both sympathetic (flight-or-fight) activity and para-sympathetic (the brain’s efforts to compensate) activity settle down dramatically using HRV techniques.
