Sleep is rarely just a symptom. Poor sleep makes depression harder to shift and anxiety harder to settle, and depression and anxiety in turn wreck sleep. It runs in both directions, which is why treating sleep on its own terms so often helps everything else, and why leaving it until last tends to slow the rest of your recovery down.
Of all the mental health uses of acupuncture, sleep is where the evidence is furthest along. The short answer is a qualified yes: people treated for chronic insomnia do report sleeping better, and that finding is now settled enough that further trials are unlikely to overturn it. Whether their sleep has objectively changed is a different question, and less resolved.
What the research shows
When researchers pool the trials in chronic insomnia, they find real improvements in sleep quality on the standard measures clinicians use, both against dummy acupuncture and against no treatment. People report falling asleep more easily, waking less through the night, and feeling better rested.
What makes this stronger than it sounds is a question the researchers went on to ask: would running more trials be likely to overturn the result? For self-reported sleep quality, the answer was no. Enough people have now been studied that the finding is unlikely to reverse. That is a firmer position than acupuncture holds for almost anything else in mental health, where the honest answer is usually that we need better studies.
What is still uncertain
Two things are worth knowing.
The first is that the trials vary a great deal, in how many sessions people had, which points were needled, and who was being treated. That variation makes an average harder to interpret, and it means your own course may look different from the one that was studied.
The second is more interesting. People consistently report sleeping better. Whether their sleep has measurably changed, when it is recorded objectively overnight, is not yet settled, simply because far fewer studies have measured it that way. There are hints of a physical basis, with melatonin rising and cortisol falling in some studies, but this is not resolved, and we would rather say so.
Where it fits
Cognitive behavioural therapy for insomnia, usually shortened to CBT-I, remains the first-line treatment, and it should stay that way. It has the deepest evidence behind it and its benefits tend to hold once the sessions end. If you have persistent insomnia and have not tried it, that is where to start.
Acupuncture is worth considering alongside it, or if you have tried it without enough benefit, or if you would rather not rely on sleeping medication long term. It carries little risk, which matters when the alternative is often a tablet you would prefer not to be taking in a year's time. We offer it as one of our complementary therapies, alongside psychiatry and psychological therapy rather than instead of them.
If sleep has been the thing quietly wearing you down, it is worth treating properly, rather than waiting for it to settle on its own. You can read more about how we approach sleep problems, or about what acupuncture offers across depression, anxiety and chronic pain.
If any of this rings true, it's worth a conversation.
