Not at all. Hypnobirthing is very different from the stage hypnosis you are probably familiar with. Hypnobirthing teaches you relaxation techniques to help relax the body and mind before and during labour and birth. You will be completely ‘with it’ but will be able to tune out of the distractions around you.
When the body and mind are in a completely relaxed state, birth can happen more quickly and comfortably because the body isn’t fighting the natural process which is taking place.
