Needles, Nerves, and Neurochemicals: The Simplified Physiology of Acupuncture

While acupuncture is rooted in ancient Chinese philosophy, its mechanisms can be explained in simple physiological terms.

Modern scientific research shows that acupuncture works by:

1. Improving circulation and tissue healing via local needle insertion.

2. Activation of the peripheral nervous system, connecting parts of the body to the brain and spinal cord by needling along nerve pathways.

3. Engaging the central nervous system, where the brain and spinal cord integrate the information, regulate physiological functions and modulate pain by triggering the release of endogenous opioids like endorphins. These opioids bind to receptors in the nervous system, reducing pain and promoting a sense of well-being.

Because pain is ultimately perceived in the brain, this combination of local circulation, nerve activation, and central nervous system modulation explains how acupuncture can reduce pain and promote whole-body healing.
