Illuminating Insomnia: A Scientometric Exploration of Complementary and Alternative Medicine in Treatment Research.

Insomnia affects millions of people worldwide, causing difficulty falling asleep or staying asleep, along with daytime fatigue and often accompanying depression and anxiety. While cognitive-behavioral therapy is considered the gold standard treatment, many people cannot access it due to cost or availability. This has led to growing interest in complementary and alternative medicine (CAM) approaches like acupuncture, yoga, meditation, and herbal remedies. Researchers analyzed over 2,200 published studies from 1970 to 2024 to understand global trends in CAM research for insomnia. They found that research in this area has grown significantly since 1998, with the United States leading publication output, followed by collaborations with the United Kingdom, China, and India. The most studied CAM approaches include acupuncture, yoga, and Ayurvedic medicine, particularly for insomnia related to cancer treatment and chronic pain conditions. While the expanding research shows promise and reflects genuine patient interest in these therapies, the authors emphasize an important limitation: there is still a lack of high-quality clinical trials proving that these treatments definitively work and are safe. Most existing studies have methodological weaknesses that prevent drawing firm conclusions. For patients considering acupuncture for insomnia, this research suggests it is an area of active scientific investigation, but more rigorous studies are needed before it can be recommended with confidence alongside conventional treatments. If you're interested in trying acupuncture for sleep problems, seek a licensed acupuncturist with specific experience treating insomnia.

This scientometric analysis evaluated 2,204 articles and reviews on complementary and alternative medicine (CAM) for insomnia published between 1970 and August 2024, retrieved from Scopus database. Using Scopus analytics, R, and VOSviewer software, researchers mapped publication trends, international collaborations, institutional contributions, and emerging research themes. Results demonstrated steady publication growth with marked acceleration since 1998, concentrated in medicine, pharmacology, and nursing disciplines. The USA leads global output with significant collaborations involving the UK, China, and India. Harvard Medical School emerged as a key contributing institution. Emerging research foci include acupuncture, yoga, and Ayurveda, particularly addressing insomnia comorbid with cancer and chronic pain. Clinical takeaway: While CAM research for insomnia shows expansion and promise, the field critically lacks rigorous, high-quality randomized controlled trials establishing definitive efficacy and safety profiles. Practitioners should counsel patients that current evidence remains insufficient for strong clinical recommendations, though continued investigation is warranted given patient demand and preliminary findings.
