Abstract

The effects of acupuncture are complex and how it works is not entirely clear. Research suggests that the needling process, and other modalities used in acupuncture, may produce their complex effects on a wide variety of ways in the brain and the body. For example, it is theorized that stimulated nerve fibers transmit signals to the spinal cord and brain, thus activating parts of what is called the central nervous system. The spinal cord and brain then release certain hormones responsible for making us feel better overall and, more specifically, feel less pain. In fact, a study using images of the brain confirmed that acupuncture increases our pain threshold, which may explain its ability to produce long-term pain relief. Also, acupuncture may increase blood circulation and body temperature. It may also affect white blood cell activity (responsible for our immune function).
