Purpose: While clinical research has shown that Tai Chi exercise may improve the sleep quality of older adults, there is a lack of robust evidence-based verification. Therefore, this study conducted a systematic review of published research on the effect of Tai Chi exercise on the sleep quality of community-dwelling older adults, aiming to provide solid evidence-based medicine to enhance their sleep quality.

Methods: A systematic search was conducted on PubMed, Embase, Cochrane Library, Web of Science, CNKI, WanFang, VIP, and SinoMed databases from their inception to December 9, 2022. The Cochrane risk of bias assessment tool 2.0 was used to assess the risk of bias in the included studies.

Results: This systematic review included 12 original articles, involving a total of 1,058 community-dwelling older adults, with 553 in the Tai Chi group and 505 in the control group. The meta-analysis results revealed a significant improvement in the sleep quality of community-dwelling older adults who practiced Tai Chi compared to the control group [WMD =  - 1.96 (95% CI: - 3.02 to - 0.90, z = 3.62, P < 0.001)]. Subgroup analysis showed that Tai Chi had significantly beneficial effects regardless of age, country/region, intervention time, and Tai Chi type.

Conclusions: Tai Chi exercise can serve as an effective non-medication approach for addressing sleep problems in this demographic. Among the various types of Tai Chi exercises, the 24-form Tai Chi exercise emerges as a preferred option. Moreover, Tai Chi exercise proves to be an excellent choice for older people in their later years, promoting their overall well-being and health.
