This study will evaluate the effect of the yoga in participants with chronic insomnia. The primary objective is to determine whether adding yoga to standard care improves insomnia severity, as measured by the Insomnia Severity Index (ISI), compared to standard care alone. The study will also assess changes in sleep architecture using polysomnography and examine dysfunctional beliefs and attitudes about sleep.
Secondary objectives include evaluating the effects of yoga on stress biomarkers (salivary cortisol and salivary alpha-amylase) and on somatosensory information processing using quantitative sensory testing. These measures aim to explore possible mechanisms by which yoga may influence insomnia symptoms, including stress modulation and sensory processing changes.
This assessor-blinded, randomized controlled trial will enroll 72 participants aged 18-65 years diagnosed with chronic insomnia. Participants will be randomly assigned to one of three groups: (1) Yoga + Standard Care (2) Stretching group + Standard Care (3) Standard Care alone. The yoga group and stretching group will receive an 8-week intervention (2 weeks supervised group sessions, followed by 6 weeks home practice with telemonitoring).
Assessments will be performed at baseline, 2 weeks, and 8 weeks. The primary outcome is change in ISI score at 8 weeks. Secondary outcomes include polysomnographic measures, dysfunctional beliefs and attitudes about sleep, depression-anxiety-stress scores, daytime sleepiness, stress biomarker levels, and sensory thresholds
Chronic insomnia is a common sleep disorder characterized by difficulty initiating or maintaining sleep, or experiencing non-restorative sleep, despite adequate opportunity for sleep, with associated daytime impairment. Current treatments, such as pharmacotherapy and cognitive behavioral therapy (CBT), have limitations including side effects, limited accessibility, and adherence challenges.
Yoga, an ancient mind-body practice, incorporates postures, breathing exercises, and meditation, and may positively influence insomnia by modulating stress responses, improving autonomic regulation, and altering sensory processing. The Common Yoga Protocol, developed by the Ministry of AYUSH, is a structured regimen combining sustained postures, breath control, and meditation.
This randomized controlled trial will assess the effect of adding the yoga protocol to standard care in participants with chronic insomnia. The primary outcome is change in insomnia severity (ISI) after 8 weeks of the intervention. Secondary outcomes include changes in sleep architecture (polysomnography), dysfunctional beliefs and attitudes about sleep, mood and anxiety symptoms (DASS-21), daytime sleepiness (Epworth Sleepiness Scale), stress biomarkers (salivary cortisol, salivary alpha-amylase), and somatosensory information processing (quantitative sensory testing after 8 weeks of the intervention.
Seventy-two participants aged 18-65 years meeting DSM-IV-TR criteria for chronic insomnia will be randomly assigned to one of three groups:
Yoga + Standard Care: Common Yoga Protocol (8 weeks: 2 weeks supervised, 6 weeks home practice with telemonitoring) plus pharmacological and/or CBT-based standard care.
Stretching group + Standard Care: Stretching group matched for duration and supervision plus standard care.
Standard Care Alone: Pharmacological and/or CBT without exercise intervention. Assessments will be conducted at baseline, 2 weeks, and 8 weeks. The trial is assessor-blinded, uses permuted block randomization, and will follow CONSORT and SPIRIT guidelines. Results may investigate the role of yoga as an adjunctive therapy for chronic insomnia.

| Yoga-intervention | Behavioral | Yoga-based mind-body program based on the Common Yoga Protocol (CYP) developed by the Ministry of AYUSH, Government of India. The protocol included a standardized sequence of yogic practices such as loosening exercises, asanas, pranayama, and relaxation/meditation techniques. A modified version of the Common Yoga Protocol with modification limited to the duration of practice, while maintaining the structure and components of the original protocol. Participants practiced yoga for 5 days per week, for a total duration of 8 weeks, 2 weeks under the supervision of a trained yoga instructor and 6 weeks of self-training which will be monitored through zoom calls by the researcher and yoga instructor. |

| Dysfunctional beliefs about sleep | The Dysfunctional Beliefs and Attitudes about Sleep (DBAS) is a self-report questionnaire designed to identify unhelpful thoughts and misconceptions that contribute to the development and persistence of insomnia. The commonly used DBAS-16 consists of 16 items that assess maladaptive beliefs related to the consequences of insomnia, worry and helplessness about sleep, unrealistic sleep expectations, and beliefs about sleep medication. Each item is rated on a Likert scale, typically from 0 to 10, with higher scores indicating more strongly endorsed dysfunctional beliefs about sleep. |
