Autonomic nervous system theory

Acupuncture stimulates the release of chemicals that serve to normalize the autonomic nervous system thereby supporting homeostasis (functional balance) and reducing pain. Typically there is quieting of the sympathetic nervous system (the so-called fight or flight response). The parasympathetic system becomes more engaged, which is more conducive to quality sleep, healthy digestion and appropriate immune response. Calming of the nervous system can also lead to improved cardiovascular functioning.
