Acupuncture works by inserting very thin needles into specific points on the body to stimulate sensory nerves under the skin and in muscles. This stimulation triggers the central nervous system to release natural chemicals, such as endorphins, which are pain-relieving substances. These biochemical changes may also promote the body’s natural healing abilities and improve physical and emotional well-being
. From a traditional Chinese medicine perspective, acupuncture is believed to work by unblocking or moving an energy called Qi (pronounced "chee") that flows through channels called meridians in the body. When Qi is blocked, it can cause illness or pain, and acupuncture aims to restore its flow to help healing
. Scientific research suggests several mechanisms for acupuncture’s effects, including:
- Activation of nerve fibers that send signals to the spinal cord and brain, leading to hormone release that reduces pain and improves health
- Increasing blood circulation and body temperature, modulating immune function, and regulating cholesterol and blood sugar levels
- Specific nerve pathways being stimulated depending on the acupuncture points used, which may explain why certain points are effective for particular conditions
Acupuncture is commonly used to treat pain (such as back pain, headaches, osteoarthritis), nausea, and other conditions. It generally requires multiple sessions to see benefits and is considered safe when performed by trained practitioners using sterile needles
. In summary, acupuncture works through a combination of nervous system stimulation, biochemical changes, and traditional energy flow concepts, resulting in pain relief and enhanced healing
