Yoga decreases insomnia in postmenopausal women: a randomized clinical trial
ABSTRACT The practice of yoga has been proven to have positive effects on reducing insomnia. Studies have also shown its effects on reducing climacteric symptoms. To date, however, no studies that evaluate the effects of yoga on postmenopausal women with a diagnosis of insomnia in a randomized clinical trial have been conducted. The aim of this study was to evaluate the effect of yoga practice on the physical and mental health and climacteric symptoms of postmenopausal women with a diagnosis of insomnia.
Postmenopausal women not undergoing hormone therapy, who were 50 to 65 years old, who had an apnea-hypopnea index less than 15, and who had a diagnosis of insomnia were randomly assigned to one of three groups, as follows: control, passive stretching, and yoga. Questionnaires were administered before and 4 months after the intervention to evaluate quality of life, anxiety and depression symptoms, climacteric symptoms, insomnia severity, daytime sleepiness, and stress. The volunteers also underwent polysomnography. The study lasted 4 months.
There were 44 volunteers at the end of the study. When compared with the control group, the yoga group had significantly lower posttreatment scores for climacteric symptoms and insomnia severity and higher scores for quality of life and resistance phase of stress. The reduction in insomnia severity in the yoga group was significantly higher than that in the control and passive-stretching groups.
This study showed that a specific sequence of yoga might be effective in reducing insomnia and menopausal symptoms as well as improving quality of life in postmenopausal women with insomnia.

ABSTRACT: Objectives. To systematically review and meta-analyze the effectiveness of yoga for menopausal symptoms. Methods. Medline, Scopus, the Cochrane Library, and PsycINFO were screened through April 2012. Randomized controlled trials (RCTs) were included if they assessed the effect of yoga on major menopausal symptoms, namely, (1) psychological symptoms, (2) somatic symptoms, (3) vasomotor symptoms, and/or (4) urogenital symptoms. For each outcome, standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated. Two authors independently assessed risk of bias using the risk of bias tool recommended by the Cochrane Back Review Group. Results. Five RCTs with 582 participants were included in the qualitative review, and 4 RCTs with 545 participants were included in the meta-analysis. There was moderate evidence for short-term effects on psychological symptoms (SMD = −0.37; 95% CI −0.67 to −0.07; P = 0.02). No evidence was found for total menopausal symptoms, somatic symptoms, vasomotor symptoms, or urogenital symptoms. Yoga was not associated with serious adverse events. Conclusion. This systematic review found moderate evidence for short-term effectiveness of yoga for psychological symptoms in menopausal women. While more rigorous research is needed to underpin these results, yoga can be preliminarily recommended as an additional intervention for women who suffer from psychological complaints associated with menopause.Evidence-based Complementary and Alternative Medicine 11/2012; 2012:863905.

ABSTRACT: An estimated 30-50% of the general population is affected by insomnia and 10% have chronic insomnia. Yoga therapy is beneficial in such disorders and it has fewer side effects. The aim of this study was to find out the effect of yoga therapy on selected psychological variables among men with insomnia. Forty males with insomnia were divided randomly into 2 groups (the experimental and the control groups). The experimental group received eight weeks of yoga therapy, while the control group did not receive any therapy. The pre and post treatment stress and the self confidence scores were taken. There was a significant improvement in the stress scores and the self confidence scores in the experimental group. There were neither any side effects nor any drop outs. We conclude that yoga is an effective treatment option for the patients with insomnia. There are no major side effects.01/2013; 7(1):55-7. DOI:10.7860/JCDR/2012/5056.2669
