![]() Due to sleep misperception, people with insomnia have a tendency to overestimate the size of their sleep problem when compared to objective assessment by polysomnography (PSG). Insomnia is closely associated with anxiety and depression and insomnia patients suffer from different forms of hyperarousal (cognitive, somatic, or cortical). depression, hypertension, immune dysfunction, poor glycemic control). In addition, this disorder can have long-term negative health consequences (i.e. Insomnia is more common in women, especially following menopause, and in older adults. Patients report fatigue and mood disturbances (International Classification of Sleep Disorders (ICSD) -3 ). Sleep complaints in insomnia are accompanied by disturbed daytime functioning. Insomnia disorder occurs when, despite adequate opportunity for sleep, patients complain of difficulties falling asleep, maintaining sleep, or experiencing sleep as non-restorative and of poor quality, and these problems occur at least three times per week for at least one month. This prevalence is increasing and rising rates of insomnia have been attributed to changes in lifestyle and environmental factors with, for example, less synchrony with natural wake-sleep rhythms. One of the most prevalent disorders is chronic insomnia (CI) with a prevalence of about 10%-22%. Sleep disorders are very common in the general population. Trial registrationĬ identifier: NCT03314441, date of registration. However, given the design of the present study, future prospective controlled studies should first confirm our results. 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. 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. ![]() In univariate correlations, decrease in PSQI was associated with increase in sleep stage N3 ( p < 0.001) on PSG. Objective sleep measurements revealed no change in PSG parameters after Yoga practice, but a decrease in arousals on actigraphy ( p < 0.001). Assessments were repeated at the end of Yoga practice. Patients practiced Viniyoga, an individualised Yoga practice with daily self-administered exercises, for 14 weeks. 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)). MethodsĪdults with CI were prospectively included in this single group pre-post study. 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. Other mind–body interventions, such as Tai-chi and Yoga, have demonstrated subjective improvements in sleep quality. First-choice treatment is cognitive behavioral therapy (CBT-I). Chronic insomnia disorder (CI) is a prevalent sleep disorder that can lead to disturbed daytime functioning and is closely associated with anxiety and depression.
