This study showed that acupuncture can significantly improve sleep quality in perimenopausal women suffering from insomnia. Participants who received real acupuncture slept better and longer than those who received placebo treatment, demonstrating that acupuncture is a safe and effective option for this specific problem.
Article summary
Plain-language narrative summary
Insomnia during perimenopause affects between 33% and 55% of women aged 40-55, causing significant impacts on quality of life and healthcare costs. Although hormone therapy and medications are effective, their adverse effects limit use. This randomized, placebo-controlled study investigated whether acupuncture can offer a safe and effective alternative. Seventy-six perimenopausal women diagnosed with insomnia by international criteria participated.
They were randomly assigned to two groups: one received real acupuncture at Shenshu (BL-23), Ganshu (BL-18), Qimen (LR-14), and Jingmen (GB-25), and the other received placebo needles at the same points. The protocol consisted of 10 sessions over 3 weeks. Point selection was based on traditional Chinese medicine theory, which identifies kidney and liver yin deficiency as the primary pathologic change in perimenopause. The chosen points aim to nourish the liver and kidney, using the special combination of dorsal Shu (背俞) and frontal Mu (募) points to balance yin-yang.
Outcomes were assessed through validated questionnaires (PSQI and ISI) and objective polysomnography. The acupuncture group showed striking improvements: PSQI reduction of 8.03 points versus only 1.29 in the placebo group. On the Insomnia Severity Index, the reduction was 11.35 points versus 2.87 in placebo. Objective polysomnography data confirmed the benefits: the acupuncture group had greater total sleep time (389 vs 320 minutes), better sleep efficiency (80% vs 67%), fewer awakenings after sleep onset, and a smaller percentage of stage 1 sleep.
Sleep architecture also improved, with increased REM sleep. No acupuncture-related adverse events were reported, confirming the safety of the treatment. Limitations include only one polysomnography night per period and the inability to blind the acupuncturist. The study provides robust evidence that acupuncture can be a valuable nonpharmacologic intervention for perimenopausal insomnia, offering both subjective and objective benefits in sleep quality.
Strengths
- 1Randomized placebo-controlled design with appropriate sham
- 2Both subjective and objective sleep evaluation
- 3Careful point selection based on TCM theory
- 4Absence of significant adverse events
Limitations
- 1Only one polysomnography night assessed per period
- 2Inability to blind the acupuncturist to the treatment
- 3Limited follow-up duration
- 4Relatively small sample for broad generalization

▸ Clinical Relevance
Perimenopausal insomnia remains one of the most frequent therapeutic challenges in women aged 40 to 55, an age group in which hormone therapy and hypnotics carry use restrictions that limit our options. This randomized placebo-controlled trial — with 76 women, 10 sessions over 3 weeks, and assessment combining validated subjective instruments and polysomnography — offers clinicians a structured, reproducible protocol. The elegance of the point selection through the dorsal Shu (背俞)–frontal Mu (募) combination, addressing the kidney and liver yin deficiency characteristic of this phase, is not mere theoretical refinement: it reflects diagnostic reasoning that allows individualized treatment based on patient pattern. Women with hormonal contraindications, history of hormone-dependent malignancies, or those who simply decline systemic medication constitute the immediate target population for this work.
▸ Notable Findings
The magnitude of the between-group difference is striking: a PSQI reduction of 8.03 points in the acupuncture group versus only 1.29 in placebo, and an ISI reduction of 11.35 points versus 2.87 — differentials that far exceed the established clinical significance thresholds for these instruments. What sets this study apart from many predecessors is the objective polysomnographic confirmation: the acupuncture group slept on average 389 minutes versus 320 in the placebo group, with sleep efficiency rising to 80% versus 67%, reduced post-sleep-onset awakenings, and proportional increase in REM sleep. The architectural improvement — less stage 1 sleep, more REM — indicates that acupuncture not only prolongs sleep but reorganizes its structure, which has direct implications for memory consolidation, emotional regulation, and daytime functional quality.
▸ From My Experience
In my practice at the Acupuncture Group of the Pain Center of HC-FMUSP, I have treated women in this age group for decades, and perimenopausal insomnia rarely presents in isolation — it almost always accompanies low back pain, anxiety, or hot flashes, allowing us to build protocols that address multiple symptoms simultaneously. I usually observe the first subjective responses — reports of faster sleep onset and fewer awakenings — between the third and fifth sessions, which aligns well with the findings of Fu et al. after 10 sessions over 3 weeks. For maintenance, I typically work with 12 to 16 total sessions, gradually spacing to biweekly and then monthly. I combine this with sleep hygiene counseling and, when there is prominent anxiety, with auriculotherapy at Shen Men (神門) and Kidney points. The best-responder profile I have observed is the patient with predominant signs of yin deficiency — nocturnal heat, sweating, red tongue without coating — exactly the pattern the authors selected as the criterion for point selection, which gives the protocol a diagnostic coherence I value.
