Acupuncture is a traditional Chinese medicine practice that uses very thin needles inserted into specific points on the body. It is commonly used as a complementary approach for pain and other symptoms.
But how does acupuncture work, and does acupuncture actually work? Research suggests that acupuncture may influence the nervous system and other tissues, although scientists do not yet fully understand all of the mechanisms involved. Evidence also varies depending on the condition being treated. In this guide, we'll explain how acupuncture works, what acupuncture is good for, potential acupuncture benefits, how long a treatment takes, what to expect during a session, possible side effects, and what to do after acupuncture.
What Is Acupuncture?
Acupuncture is a treatment that involves inserting thin needles into specific points on the body, often called acupuncture points or acupoints. The practice originated in traditional Chinese medicine and is now used in many countries. In modern healthcare, acupuncture is often used as a complementary treatment alongside conventional medical care. During an acupuncture session, a trained practitioner inserts sterile, single-use needles into selected areas of the body. Depending on the treatment, the needles may remain in place for several minutes.
How Does Acupuncture Work?
The question "acupuncture how does it work?" does not have one definitive scientific answer.
Traditional Chinese medicine explains acupuncture in terms of qi, a form of energy believed to flow through pathways called meridians. Modern research approaches acupuncture differently, examining how needle stimulation may affect the nervous system, connective tissues, and other physiological processes.
Research suggests that acupuncture may:
- Influence nervous system activity.
- Affect tissues around the areas where needles are inserted.
- Trigger the release or regulation of certain natural chemicals.
- Affect how the body processes pain signals.
- Produce effects related to the treatment experience and patient expectations.
However, how acupuncture works scientifically is not completely understood, and researchers continue to study its mechanisms.
Does Acupuncture Work?
The answer depends on the health condition being treated and what outcome is being measured. Research has found that acupuncture may provide benefits for certain pain conditions, including some types of back or neck pain, knee osteoarthritis pain, and headaches or migraines. The strength of evidence varies by condition. Acupuncture should not be considered a replacement for necessary medical treatment. It is often used as a complementary approach alongside other forms of care.
What Is Acupuncture Good For?
People commonly use acupuncture for pain and other symptoms. Research has examined acupuncture for a wide range of conditions. Some areas where acupuncture has been studied include:
- Back and neck pain.
- Knee osteoarthritis pain.
- Headaches and migraines.
- Some types of postoperative pain.
- Joint pain associated with certain cancer treatments.
- Menstrual pain.
- Seasonal allergy symptoms.
- Nausea and vomiting associated with cancer treatment.
The evidence is not equally strong for every condition. Some conditions have more supportive research than others, so it is important to consider the specific health problem rather than assuming acupuncture works for every condition.
Acupuncture Benefits
Potential acupuncture benefits depend on the condition and individual response.
- May Help With Certain Types of Pain - Acupuncture has been studied for several pain conditions, including back pain, neck pain, osteoarthritis-related knee pain, and headaches. Research suggests it may provide pain relief for some people.
- May Complement Other Treatments - Acupuncture can be used alongside conventional medical treatment rather than necessarily replacing it. For example, people with chronic pain may use acupuncture as one component of a broader treatment plan.
- May Affect the Nervous System - Studies involving humans and animals suggest acupuncture can influence nervous system function. Researchers are continuing to investigate how these changes relate to symptom relief.
- May Support Symptom Management - Acupuncture has also been studied for symptoms such as seasonal allergy symptoms, treatment-related nausea, and certain menopause-related symptoms, although the evidence differs across conditions.
How Does Acupuncture Stimulate Healing?
Acupuncture should not be described as directly "healing" every condition. Instead, research suggests that acupuncture may influence processes involved in pain perception and nervous system activity.
When a needle is inserted and stimulated, the body receives sensory input from that area. Research has found that acupuncture can affect nervous system function and may also produce local effects in the tissues surrounding the needle. The exact relationship between these physiological effects and symptom improvement is still being studied.
What Happens During an Acupuncture Treatment?
If you have never had acupuncture before, knowing what to expect can make the process easier.
- Initial Consultation - Your practitioner will usually ask about your symptoms, health history, and treatment goals. They may also examine the areas relevant to your symptoms before selecting acupuncture points.
- Needle Placement - The practitioner inserts very thin, sterile needles into selected acupuncture points. Needles may be inserted into different areas depending on the treatment plan.
- Needle Stimulation - Depending on the technique being used, the practitioner may gently manipulate the needles or use other forms of stimulation.
- Rest During Treatment - The needles may remain in place for several minutes. Cleveland Clinic notes that acupuncture needles may remain in place for a few minutes or up to around 20 minutes, depending on the treatment.
- Needle Removal - The practitioner removes the needles after the treatment period and disposes of single-use needles appropriately.
Does Acupuncture Hurt?
Acupuncture needles are very thin, so many people experience only a small prick when they are inserted. You may also notice sensations such as:
- Tingling.
- Dull aching.
- Pressure.
- Heaviness.
- A brief muscle sensation.
Experiences vary between people and depending on the treatment area. If you experience significant pain during treatment, tell the practitioner so they can assess the needle position and stimulation.
How Long Does Acupuncture Take?
The length of an acupuncture appointment varies depending on the practitioner, treatment plan, and condition being addressed. The actual needle portion of a treatment may last several minutes to around 20 minutes, while the complete appointment can be longer because it may include an initial consultation and assessment.
How Long Does It Take for Acupuncture to Work?
There is no universal timeframe for when someone will notice an effect. Some people may notice changes after an individual session, while others may require multiple sessions. The response depends on the condition, treatment approach, and individual. Cleveland Clinic notes that some people may not experience the full benefits during the first or second treatment and that treatment frequency varies according to the condition and response.
What to Do After Acupuncture
Knowing what to do after acupuncture can help you transition comfortably after a session. After treatment:
- Give yourself time to relax if you feel tired.
- Drink fluids according to your normal routine.
- Follow any specific instructions provided by your practitioner.
- Pay attention to how your body feels.
- Avoid pushing through significant discomfort.
- Continue prescribed medications unless your healthcare provider tells you otherwise.
Some people may feel relaxed or tired after acupuncture. Cleveland Clinic recommends allowing time to rest before driving if you feel affected by the treatment.
Potential Risks and Side Effects of Acupuncture
Acupuncture is generally considered to have relatively few complications when performed appropriately by a qualified practitioner using sterile needles. However, side effects and complications can occur. Possible effects include:
- Minor bleeding.
- Bruising.
- Temporary soreness.
- Pain at the needle site.
- Dizziness or lightheadedness.
More serious complications can occur when acupuncture is performed improperly or with nonsterile needles. These can include infection, punctured organs, or injury to the central nervous system.
How to Make Acupuncture Safer
Choosing a qualified practitioner and ensuring sterile, single-use needles are used are important safety considerations. Before treatment:
- Tell the practitioner about your health conditions.
- Mention medications you take.
- Inform them if you are pregnant or may be pregnant.
- Ask about their qualifications and experience.
- Confirm that sterile, single-use needles are being used.
- Follow aftercare instructions provided by your practitioner.
Certain medical conditions or circumstances may require modifications or additional precautions, so discuss acupuncture with your healthcare provider if you have concerns.
How Often Should You Get Acupuncture?
There is no single schedule that works for everyone. Treatment frequency can depend on:
- The condition being treated.
- Severity and duration of symptoms.
- Your response to treatment.
- The practitioner's treatment plan.
Some people may receive acupuncture once a week, while others may have sessions more or less frequently. Your practitioner can recommend an appropriate schedule based on your individual situation.
Acupuncture vs. Other Pain Management Options
Acupuncture is often used as one part of a broader approach to managing pain or symptoms. Depending on the condition, treatment may also involve:
- Physical therapy.
- Exercise or movement programs.
- Medications.
- Lifestyle changes.
- Other complementary therapies.
Acupuncture should not be used to postpone evaluation or treatment of a medical condition that requires professional care.
Who Should Talk to a Healthcare Professional Before Acupuncture?
Talk with your healthcare provider before trying acupuncture if you:
- Are pregnant.
- Have a significant medical condition.
- Take medications that may affect bleeding.
- Have concerns about infection or healing.
- Are unsure whether acupuncture is appropriate for your symptoms.
Your healthcare provider can help determine whether acupuncture fits into your overall treatment plan.
