How does acupuncture work from a Western or modern medicine view?
The effects of acupuncture are complex. How it works is not entirely clear through the eyes of modern medicine. Research suggests that the needling process, and other techniques used in acupuncture, may produce a variety of effects in the body and the brain. One theory is that stimulated nerve fibers transmit signals to the spinal cord and brain, activating the body’s central nervous system. The spinal cord and brain then release hormones responsible for making us feel less pain while improving overall health. A study using images of the brain confirmed that acupuncture increases our pain threshold, which may explain why it produces long-term pain relief. Acupuncture may also increase blood circulation and body temperature, affect white blood cell activity (responsible for our immune function), reduce cholesterol and triglyceride levels, and regulate blood sugar levels.
