Though acupuncture has ancient Chinese roots and a philosophical basis in Qi (life energy) and meridians, modern science has been exploring its neurological effects. The traditional view is that acupuncture restores the flow of Qi to relieve pain and promote healing by inserting fine needles into specific meridian points. Treatments may include heat (moxibustion) or mild electrical stimulation.
Scientific theories suggest that acupuncture triggers the release of opioid peptides—like endorphins, enkephalins, and dynorphins—in the nervous system. These neurotransmitters reduce pain perception and help the body reset dysfunctional pain loops. Acupuncture may also stimulate the nervous system to “close the gate” on pain signals (Gate Control Theory), thus relieving discomfort.
Other key concepts include:
- Pain memory: Acupuncture may interrupt ingrained pain patterns in the nervous system, allowing healing.
- Trigger points: Specific areas on the body associated with referred pain closely align with acupuncture points. Treating these can relieve muscle tension and pain.
While Western science hasn’t fully explained acupuncture’s effects, evidence continues to support its value in managing pain and enhancing healing—through both traditional Chinese and modern biomedical lenses.
