In supine position, then a few deep abdominal breaths and The diaphragm is closed and comfortable in the best condition in which it relaxes. By providing a quiet, quiet environment and by minimizing environmental stimuli (such as low light, travel restrictions), the client will watch virtual reality imagery.
