Acupuncture needles stimulate the peripheral nervous system when inserted into specific points on the body, encouraging production and increased flow of neurotransmitters – chemicals which help the nerves in your body communicate. This stimulation also encourages the release of endorphins from the brain, which is the body’s natural pain reliever. Acupuncture has also been shown to improve blood flow to the skin, muscles, brain, and other internal organs. These actions combine to help decrease pain, improve circulation, strengthen the immune system, decrease muscle tightness, increase joint flexibility, and regulate actions of the nervous system throughout your body.
