Needles, Nerves, and Neurochemicals: The Simplified Physiology of Acupuncture
How Acupuncture Works
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 local circulation: Supporting blood flow and tissue healing where the needles are placed.
2. Activating the peripheral nervous system: Connecting different parts of the body with the brain and spinal cord.
3. Engaging the central nervous system: Where the brain and spinal cord integrate signals, regulate physiological functions, and modulate pain.
This process also triggers the release of endogenous opioids like endorphins. These natural chemicals bind to receptors in the nervous system, reducing pain and promoting a sense of well-being.
Because pain is ultimately processed in the brain, this combination — better circulation, nerve activation, and central nervous system modulation — explains how acupuncture reduces pain and supports whole-body healing.
