Oxytocin is essentially the star of the show. Oxytocin is the hormone of love, is produced when we fall in love or when we make love. It is also essential for your starting contractions.
More oxytocin that you have in your body, the faster and more effective your birth will be. Indeed, oxytocin causes the muscles to function at full capacity so that your cervix softens and pulls up in preparation for the birth.
More of this hormone you produce better and easier you will experience birth. In quiet mode, your body can produce large amounts of oxytocin.
