Effect of a Home-Based Simplified Tai Chi Exercise Program on Sleep Quality, Daytime Sleepiness, Quality of Life, and Psychological Well-Being in Egyptian Older Adults: A Quasi-Experimental Study.

 Sleep disturbances are common among older adults and can have detrimental effects on their overall well-being. Tai Chi exercise has shown promise in improving sleep quality, quality of life (QoL), and psychological well-being in various populations.  To investigate the effect of a home-based simplified Tai Chi exercise program on sleep quality, daytime sleepiness, QoL, and psychological well-being in Egyptian older adults.  A quasi-experimental design was employed, with 152 participants aged 60 years and above assigned to either an experimental group (= 87) or a control group (= 65). Thecontrol group received a health education program to improve their sleeping quality and life-style, while the experimental group received a similar health education program and Tai Chi exercise training program. The participants in the experimental group were instructed to perform 3 months Tai Chi exercise. Data on sleep quality, daytime sleepiness, QoL, generalized anxiety disorder (GAD), and depression symptoms were collected at baseline, and one month, and 3 months post-intervention using validated questionnaires. Repeated measures ANOVA was done to investigate the effectiveness of the intervention programsover 3 time periods.  The results showed significant improvements in sleep quality (< .001), QoL (< .005), GAD (< .005), and depression symptoms (< .005) post-interventions. Also, there were significant difference in the effectiveness of the intervention programs between both the experimental and control groups. The experimental group exhibited greater improvements compared to the control group.  The findings support the beneficial effects of a home-based simplified Tai Chi exercise program on sleep quality, QoL, and psychological well-being in Egyptian older adults. These results have important implications for promoting healthy aging and improving overall well-being in this population. Further research is recommended to validate these findings and explore the underlying mechanisms of Tai Chi exercise on the outcomes of interest.
