The nervous system is split up into two parts: the sympathetic (fight or flight) and parasympathetic (rest and digest). When a woman is experiencing lots of physical, mental, and/or emotional stress, the sympathetic nervous system becomes over stimulated as a defense mechanism. An over sympathetic response can lead to changes in monthly cycles, fertility, and hormone balance. Chiropractic is excellent at down-regulating your sympathetics and stimulating the parasympathetic nervous system. This allows a woman's body to be in a lesser state of defense, and ready to grow and heal.
