What Is Acupuncture — And What It Actually Does in the Body

Most people think acupuncture is just “tiny needles” or “ancient Chinese medicine.”

Not totally wrong — but leaves a lot to be answered.

So what is acupuncture, really?

Here’s the short answer: Acupuncture is a time-tested, research-supported medical therapy that stimulates the nervous system to regulate pain, inflammation, and stress. Very thin, sterile needles are placed at specific points to trigger measurable physiological responses.

If that satisfies your curiosity, fantastic. Enjoy your new fun fact about needles and book a no-charge consult.

But if you want to know what acupuncture really does, how it works, and why modern clinicians still use a 3,000+ year-old method in 2025… grab your coffee (I’m sipping mine while writing) and settle in.

Many people only know acupuncture from TV scenes or spa menus — and honestly, that’s not their fault. Non-pharmaceutical therapies often don’t receive the same level of funding, attention, or press coverage. But the evidence supporting acupuncture for pain, nausea, stress, recovery, and more has been building for decades.

Before we get into what acupuncture can do for you, let’s start with what it actually is.

What Acupuncture Actually Is

Acupuncture began more than 2,000 years ago — long before MRIs, cortisol labs, or ergonomic desk chairs — but its staying power isn’t an accident. Historically, it was used to treat everything from digestive issues to pain to emotional distress. And while the cultural framework looked different then, the goal hasn’t changed: help the body heal itself by nudging the nervous system back into balance.

When a needle is inserted (don’t worry, they’re the width of a human hair), your body responds in several measurable ways:

  • Your brain releases natural painkillers. Studies show increased endorphins, enkephalins, and other neurotransmitters that regulate pain and mood.
  • Your nervous system shifts out of fight-or-flight. Acupuncture activates parasympathetic activity — think “rest, digest, and repair” mode.
  • Local blood flow increases. Needles improve circulation to injured or inflamed tissues.
  • Your immune system responds. Research shows changes in cytokines — those little chemical messengers involved in inflammation and healing.

This is why acupuncture offers much more than relaxation. It’s a regulated medical practice used in hospitals, oncology centers, fertility clinics, the military, and pain institutes across the U.S.

What Acupuncture Feels Like (Because Yes, People Want to Know)

The biggest fear most new patients have is the needle.

Then they feel the first one and say, “Oh… that’s it?”

Acupuncture needles are:

  • Solid, not hollow
  • About 1/10th the thickness of a standard flu shot
  • Designed to glide through tissue, not puncture it aggressively

Most sensations range from nothing at all to a dull ache, heaviness, warmth, or a satisfying “release.” Many people fall asleep, which we take as a compliment, even if they snore.

So… What Does Acupuncture Do?

Here’s where things get fun. Acupuncture isn’t a one-trick therapy — because the nervous system isn’t a one-trick system.

Below are the most well-researched benefits, explained without putting you to sleep:

1. Pain Relief (the big one)

Acupuncture is one of the most widely studied treatments for chronic and acute pain. Patients are often able to manage pain with acupuncture in place of additional pain medications. It’s been shown to help with:

  • Back pain
  • Neck pain
  • Arthritic conditions (knee, hip, hands, etc.)
  • Migraines and tension headaches
  • Sciatica
  • Post-surgical pain
  • Fibromyalgia pain

2. Stress, Anxiety, and Burnout Regulation

If cortisol had a fan club, it would be too big. Nearly everyone deals with stress, and acupuncture helps to regulate the autonomic nervous system, lowering physiological stress markers and promoting deep relaxation.
This is why so many patients say they feel “reset” afterward.

3. Nausea & Digestive Support

  • Acupuncture is commonly recommended for:
  • Chemotherapy-induced nausea
  • Postoperative nausea
  • Pregnancy-related nausea

4. Hormones, Fertility, & Reproductive Health

Acupuncture can support menstrual health, regulate cycles, reduce PMS, and is used in fertility medicine to improve blood flow, reduce stress, and support IVF outcomes. It is also used to support women as they go through the stages of menopause, whether medically induced or as they age naturally.

5. Recovery & Performance

  • Athletes love acupuncture because it helps with:
  • Muscle tension
  • Injury recovery
  • Circulation
  • Faster return to training

Even professional teams use it — because anything that helps tissue heal faster is gold.

But How Does Sticking Needles in My Ankle Help My Shoulder?

Great question.

Short answer: Your body is one connected system — not a collection of isolated parts.

Longer answer: Neural pathways, fascial lines, and circulatory networks connect distant regions of the body. Stimulating a point on your leg can influence reflex arcs, blood flow, and neuromuscular activity all the way up the chain.

This is also why experienced acupuncturists often treat both the area where it hurts and the reason why it hurts — addressing both the symptom and the underlying pattern.

Why Acupuncture Still Matters in 2026

We live in an age of incredible medicine. But we also live in an age of skyrocketing stress, chronic pain, poor sleep, and conditions that don’t always respond well to medication.

  • Acupuncture fills a gap:
  • It treats the nervous system directly.
  • It reduces pain without drugs.
  • It complements a wide range of other therapies and modalities.
  • And most importantly, it helps people feel like themselves again.

In a world where people are tired of “just dealing with it,” acupuncture gives the body permission to heal.

So, Should You Try It?

Honestly? If you’ve read this far, something in your body is probably asking for support.

The best way to find out if acupuncture can help you is to schedule a consultation! That way, you can get the answers without having to question or guess if it’s a good fit for you. Give us a call to get scheduled or to ask any questions you might have about how acupuncture can help you.
