How does Acupuncture work?

Acupuncture stimulates the body’s ability to resist or overcome illnesses and conditions by correcting imbalances. Acupuncture also prompts the body to produce chemicals that decrease or eliminate painful sensations.

There are hundreds of acupuncture points (called acu-points) along the body’s 12 major meridians (energy-carrying channels). The term “Qi” (pronounced “chee”) is used to describe the energy that flows through meridians. The belief is that illness is caused by a disruption of Qi, which leads to an imbalance of energy. Acupuncture can correct this energy disruption.

There are many theories as to how acupuncture actually works. When acupuncture points are stimulated, it causes a dull ache or other sensations in the muscle. One theory holds that:

  • The stimulated muscle and sensory neurons send a message to the central nervous system (the brain and spinal cord);

  • This causes the release of endorphins (naturally produced painkillers) and other neurotransmitters (body chemicals that modify nerve impulses);

  • This, in turn, helps block the message of pain from being delivered to the brain (and has other regulatory effects as well).​

Other experts believe that acupuncture works by transmitting signals via the fascia. Fascia is like a thin sheath that surrounds all of the body’s muscles. Some acupuncturists consider the meridians to represent myofascial chains, which helps explain why stimulating an acupuncture point in the lower leg can affect the back or other areas. Interestingly, research shows that acupuncture points have a lower electrical resistivity than surrounding areas. In a practical sense, the meridian system provides a navigable energetic map of the body for acupuncturists to locate and treat many conditions.
