Pain (despite being complicated) is relevant to your perceptions and neurology. Hypnobirthing works with the idea that pain is increased by tension and fear during childbirth, constricting muscles and slowing down your progress. When a mother can condition herself to soften through intense sensations and release endorphins (or natural pain relief), her experience of pain may be lessened. Hypnobirthing does not promise no pain, but often hypnobirthing mothers describe the experience as one of working with their bodies through the waves and sensations, not as unbearable and horrific.
