How does acupuncture work? Chinese medicine calls the energy that flows through your body qi. Chinese medicine practitioners believe qi disruptions create imbalances in your body’s energy that lead to illness. Some forms of acupuncture aim to rebalance qi with needles that touch acupuncture points (acupoints) throughout your body. There are hundreds of acupoints in your body along 14 major meridians, also called energy-carrying channels. The needles stimulate your body’s central nervous system and immune system to: React to an illness or symptom. Rebalance your body. Release natural chemicals, such as endorphins, your body’s natural painkillers, and neurotransmitters, chemicals that control nerve impulses. What happens during an acupuncture treatment? During your first appointment, your acupuncturist will talk to you about your condition. Then, they’ll examine your body for areas that’ll react to acupuncture. Your acupuncturist will tap the needles into points in your skin throughout your body. The acupuncture needles are sterile, disposable and as thin as a human hair. Your acupuncturist inserts needles at various depths, from a fraction of an inch to a couple of inches. The needles stay in for a few minutes or as long as 20 minutes. Does acupuncture hurt? You may feel a small prick with each needle. It’s less painful than the feeling when you get a vaccine or blood draw. Acupuncture needles are much thinner than medical needles. And they’re solid, not hollow. The needles may cause some muscle sensations, such as dull aches or tingling. Your practitioner will ask you to report when you feel a deep heaviness or numbness. Those sensations usually mean the treatment is working. What happens after an acupuncture treatment? Acupuncture has a calming effect, so you may want to get a ride home from your appointments — especially the first one. If that’s not possible, try to rest for five to 10 minutes before you drive. Your practitioner may suggest that you take it easy for a day or two after each session.
