Tailored individual Yoga practice improves sleep quality, fatigue, anxiety, and depression in chronic insomnia disorder

BACKGROUND

Chronic insomnia disorder (CI) is a prevalent sleep disorder that can lead to disturbed daytime functioning and is closely associated with anxiety and depression. First-choice treatment is cognitive behavioral therapy (CBT-I). Other mind-body interventions, such as Tai-chi and Yoga, have demonstrated subjective improvements in sleep quality. The purpose of this study was to assess the efficacy of Yoga for improvement of subjective and objective sleep quality as well as measures of anxiety, depression, sleepiness, and fatigue in patients with CI.

METHODS

Adults with CI were prospectively included in this single group pre-post study. Baseline assessments included home polysomnography (PSG), 7-day actigraphy, and questionnaires (Pittsburgh Sleep Quality Index questionnaire (PSQI), Hospital Anxiety Depression scale (HADS), Epworth Sleepiness Scale (ESS), Pichot fatigue scale (PS)). Patients practiced Viniyoga, an individualised Yoga practice with daily self-administered exercises, for 14 weeks. Assessments were repeated at the end of Yoga practice.

RESULTS

Twenty-one patients completed the study. Objective sleep measurements revealed no change in PSG parameters after Yoga practice, but a decrease in arousals on actigraphy (p < 0.001). Subjective symptoms improved for all questionnaires (PSQI, p < 0.001; HAD-A, p = 0.020, HAD-D, p = 0.001, ESS, p = 0.041, PS, p = 0.010). In univariate correlations, decrease in PSQI was associated with increase in sleep stage N3 (p < 0.001) on PSG.

CONCLUSIONS

We have demonstrated a positive impact of individualized Yoga practice on subjective parameters related to sleep and daytime symptoms in CI, resulting in fewer arousals on actigraphy. Yoga could be proposed as a potentially useful alternative to CBT-I in CI, as it is easy to practice autonomously over the long-term. However, given the design of the present study, future prospective controlled studies should first confirm our results.

Beyond Scientific Mechanisms: Subjective Perceptions with Viniyoga Meditation

Healthcare professionals and research scientists generally recognize the potential value of mind-body practices grounded in ancient wisdom, but often have limited direct experience with such practices. Meditation participant self-reports provide a window into subjective experiences of three Viniyoga meditations and how and why those meditations could contribute to health and well-being outcomes. Each of the meditations in this analysis had a unique structure and used a different aspect of the ocean as a meditation object. Yoga philosophy and yoga anatomy models of the human system are used to help explain participants' experiences and associated personal benefits and insights. Four aspects of the individual that can influence what happens for them in meditation are illustrated with tangible examples: (1) What is happening in generally in someone's life; (2) the state of their system (mind, body, breath) around the time of the meditation; (3) reactions to the meditation steps and instructions; and (4) their prior experiences with the object of meditation. Summaries of the practices, and why and for whom each meditation might be beneficial are discussed. The authors' perspectives are grounded in Viniyoga and yoga therapy.
