Several processes have been proposed to explain the effects of acupuncture, with a primary focus on pain. Acupuncture points are known to stimulate the central nervous system (the brain and spinal cord) to release chemicals into the muscles, spinal cord, and brain. These chemicals either change the experience of pain or release other chemicals and hormones, which influence the body’s self-regulating systems. The biochemical changes stimulate the body’s natural healing abilities and promote physical and emotional well-being. There are three main mechanisms:
Conduction of electromagnetic signals: scientists have found evidence that acupuncture points are strategic conductors of electromagnetic signals. Stimulating points along these pathways through acupuncture enables electromagnetic signals to be relayed at a greater rate than under normal conditions. These signals may start the flow of pain-killing biochemicals, such as endorphins, and of immune system cells to specific sites in the body that are injured or vulnerable to disease.
Activation of opioid systems: Research has found that several types of opioids may be released into the central nervous system during acupuncture treatment, thereby reducing pain.
Changes in brain chemistry, sensation, and involuntary body functions: Studies have shown that acupuncture may alter brain chemistry by changing the release of neurotransmitters and neurohormones. Acupuncture also has been documented to affect the parts of the central nervous system related to sensation and involuntary body functions, such as immune reactions and processes whereby a person’s blood pressure, blood flow, and body temperature are regulated.
Increasingly, acupuncture is complementing conventional therapies. For example, doctors may combine acupuncture and drugs to control surgery-related pain in their patients. By providing both acupuncture and certain conventional anesthetic drugs, some doctors have found it possible to achieve a state of complete pain relief for some patients. They also have found that using acupuncture lowers the
need for conventional pain-killing drugs and thus reduces the risk of side effects for patients who take the drugs
