Background. Maternal mental health is essential for maintaining family stability and promoting adolescent growth. Mothers experience difficulties in combining emotional support with independence, underlining the need for interventions that address their mental well-being.

Research objective. The purpose of this study is to fill a research gap by examining the effects of a long-term yoga intervention on psychological measures and sleep quality in mothers of adolescent children.

Methods. Forty mothers of adolescent children participated in a randomized controlled study that measured their depression, stress, anxiety, and sleep quality both before and after the intervention program.

Results. Based on statistical analysis, an independent t-test showed that no significant differences were observed between the groups in the baseline assessment. A paired t-test showed that the yoga group exhibited significant improvements: depression (p < 0.001) with a 31.06% reduction, stress (p < 0.001) with a 50.63% reduction, anxiety (p < 0.001) with a 17.79% reduction, and sleep quality (p < 0.001) with a 31.32% improvement. In contrast, the control group showed no significant changes in depression (p = 0.19), stress (p = 0.43), anxiety (p = 0.34), or sleep quality (p = 0.67).

Conclusions. This study concludes that a long-term yoga intervention significantly improves mental health in mothers of adolescents, reducing depression, stress, and anxiety while enhancing sleep quality. This study emphasizes the need to implement targeted mental health programs globally by addressing the complex interaction of emotional health and family dynamics.
