If you’ve spent time around dogs (or any pets, really), you know what happens when they’ve been startled one too many times. They flinch at small sounds, freeze at sudden movements, or overreact to the slightest triggers. Even when there’s no real threat, their bodies stay braced as if danger is always just around the corner.
Now imagine trying to teach an unsettled dog a new trick. You wouldn’t do it by shouting louder, or by forcing them into submission. You would do it by being patient and gentle in your approach, and by consistently rewarding them with small praises, treats, and pats until one day… the dog doesn’t flinch from your attempt to connect.
The same is true for humans.
There’s a question I hear in the clinic often: “I didn’t feel much after the first session… is that normal?” The answer is yes. In fact, it’s expected.
After 25 years of using acupuncture to support patients with depression, anxiety, chronic stress and burnout, I’ve found that the most powerful changes often happen slowly, almost imperceptibly… until they’re undeniable.
I call it the Microdose Effect.
In this blog, we’ll explore how consistent acupuncture treatments gradually retrain the nervous system, soothe emotional reactivity, and restore a deep sense of safety in the body.
Microdose Effect: The body learns by repetition
Our fast-paced society conditions us to always look for instant breakthroughs, immediate relief, or dramatic results. But just because healing doesn’t announce itself loudly or immediately, it doesn’t mean it’s not there. Your nervous system could be subtly shifting in ways that take time to translate into noticeable sensations.
It’s like a soft click inside the body, a sense that something’s been realigned.
As the lyrics from Roald Dahl’s Matilda the Musical so beautifully put it:
In the slip of a bolt, there’s a tiny revolt
The seed of a war in the creak of a floorboard
A storm can begin with the flap of a wing
The tiniest mite packs the mightiest sting
Every day starts with the tick of a clock
All escapes start with the click of a lock
That’s what the Microdose Effect is: small, repeated interventions that slowly teach the nervous system how to regulate again.
So what does an unsettled nervous system look like? It doesn’t show exclusively in the form of panic attacks or emotional breakdowns. It might also look like snapping at a loved one for no reason, or waking up with a pit in your stomach every morning, or feeling constantly on edge even in calm environments.
Just like the startled dog, you can’t brute-force your nervous system into safety. You have to meet it with compassion, again and again until one day, it doesn’t brace for impact anymore.
Why consistency beats intensity
When I first began my acupuncture training, I was drawn to the elegant simplicity of the process. It only takes a few needles in a quiet room, and some sessions can last a few minutes. Patients won’t always notice a dramatic effect immediately, but over time, the internal shift is cumulative.
In my book, Stick It To Depression: Another Tool in Your Doctor’s Handbag, I share the story of a 45-year-old female shop owner who came to me after a traumatic head injury from a horse-riding accident. She was off work for 12 months and, even after her physical injuries had healed, she remained severely depressed and unable to work.
She had lost her confidence, felt anxious in public, and couldn’t face the demands of her business. Panic attacks were frequent. She had tried antidepressants and psychotherapy with limited results.
Eventually, she completed a full course of 12 weekly Transformational Acupuncture treatments and continued with monthly follow-up sessions for a year. Over this time, her mood gradually improved, and she regained the confidence to resume work. Her panic attacks stopped. Remarkably, her friends noticed the changes even before she did.
The turning point for that patient wasn’t a sudden breakthrough, and it wasn’t loud. Instead, the healing happened as a layered, steady accumulation of small shifts that helped her reclaim her sense of self.
Science is catching up
A 2022 study¹ showed a clear dose‑effect relationship: people who attended more acupuncture sessions consistently demonstrated greater improvement in depression severity. There was a trend toward increased effectiveness with 10–12 sessions or more, suggesting that acupuncture’s antidepressant effect is cumulative.
Meanwhile, a 2024 systematic review² reported that acupuncture influences multiple biological systems in rodent models, supporting brain plasticity, reducing neuroinflammation, and rebalancing neurotransmitters like serotonin and dopamine.
While we don’t yet have conclusive human brain‑imaging data, these findings suggest a biological foundation for why repeated acupuncture treatments might gradually support nervous system regulation and emotional resilience in humans.
These studies highlight the importance of the patient’s choice to constantly show up to sessions. Healing takes commitment, because emotional regulation doesn’t return all at once. It returns in moments like a calmer reaction to stress, a deeper night’s sleep, or a week without that familiar dread in the morning.
While science is only just beginning to explain why this happens, as practitioners, we’ve known it intuitively for decades. When we treat the nervous system consistently (not aggressively), we create space for safety to return and healing to take shape.
What Makes Transformational Acupuncture Different
When I began practicing as a GP 40 years ago, I was trained to diagnose, prescribe, and look for outcomes. If the symptom disappears, that must mean the treatment worked. But if the symptom is still there, it must be time to try something else!
Acupuncture, on the other hand, works in a different way.
Transformational Acupuncture is a framework of holistic therapy I developed over two decades ago to lean in more to the human behind the symptoms, and listen to their stories. The goal is not to get as fast as possible to a breakthrough, so that we may say that the patient has healed, and our job here is done. Our aim is to give the body enough chances to feel safe until safety becomes its default again.
Each needle sends a message to the nervous system: You can let go now. If we send that message often enough, the body begins to believe it.
Picture it like a quiet river wearing down stone over time: it’s unnoticeable, consistent, and transformative. In the same way, acupuncture targets specific points on the body that are known to influence the vagus nerve, calm the sympathetic nervous system, and activate pathways associated with emotional regulation. Over time, this repeated stimulation helps recondition the body’s baseline response to stress.
I’ve had patients come back after several weeks and say things like:
- “I didn’t realise how reactive I used to be until I wasn’t anymore.”
- “I feel more myself, but I couldn’t tell you when it started.”
- “It’s like the volume on my inner critic is lower.”
For the Practitioner: Track the invisible wins
If you’re a practitioner reading this, you know how easy it is to doubt yourself when patients don’t report immediate improvement.
My advice is to look for the subtleties. Has their voice softened since the first visit? Do they make more eye contact? Has anything changed in their choice of language, from using heavy metaphors to telling light-hearted stories?
When we attune ourselves to these microsignals and stop pushing for instant change, we become better witnesses to healing. As long as we hold that faith as practitioners, our patients often find the courage to keep showing up.
For the Patient: Healing doesn’t only happen when you feel it
This may sound strange, but I often say, you don’t have to feel better to be getting better.
In fact, healing may not always feel good! Sometimes it might feel like confusion or boredom. The very thing you thought was proof that nothing is happening… might actually be the space where something new is taking root.
If you’re a patient reading this or supporting a loved one through a healing journey, and you’re not sure if acupuncture is doing anything, I invite you to ask:
- Do I find myself choosing to pause before reacting, even when I’m upset?
- Have I stopped ruminating about something that used to consume me?
- Am I more aware of how tension shows up in my body – like shallow breathing, tight shoulders, or clenching my jaw?
- Am I spending less energy bracing for the worst?
- Have other people commented that I seem calmer, even if I haven’t noticed it myself?
These are small questions, but they often hold big truths.
Final Thoughts
The Microdose Effect doesn’t erase symptoms overnight. In every acupuncture session, it offers the body tiny recalibrations that gradually reshape how a person relates to stress, emotion, and the world around them.
At the end of the day, what matters most is that the person who is healing chooses to show up, and the practitioner behind the healing commits to being present and perceptive, even when progress is hard to measure.
When we harness the Microdose Effect of Transformational Acupuncture, we meet the nervous system the same way we’d approach the startled dog: with patience and reassurance, again and again, until one day… it trusts. It feels safe.
