Yoga as a Treatment for Insomnia

Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the effectiveness of a daily, 8-week treatment for insomnia using yoga, relaxation exercises or sleep hygiene.

Clinical Trial Description

Insomnia is a sleep disorder characterized by a chronic difficulty in initiating and maintaining sleep which has a relatively high prevalence and a significant socioeconomic cost. There is good evidence that cognitive and/or physiological arousal, associated with sustained sympathetic activation, is one of the underlying causes of insomnia. Relaxation treatments such as progressive relaxation and meditation which address the cognitive and somatic arousal associated with insomnia have been found to be effective. Yoga is a comprehensive discipline which includes physical exercises, postures, breathing techniques, and meditation, for the purpose of improving health and well being. Research studies have documented the effectiveness of yoga in reducing sympathetic activation and cognitive and somatic arousal and in the treatment of specific medical disorders. Although it has been used and recommended for the treatment of insomnia, its effectiveness has not been evaluated in a randomized, controlled study. The aim of this proposal is to evaluate the effectiveness of yoga, relaxation exercises or sleep hygiene in the treatment of chronic psychophysiological insomnia. A subjective measure of sleep onset latency will be derived from daily sleep diaries, and an objective measure will be drawn from polysomnographic recordings. Sleep onset latency will be evaluated before and after a two month treatment period in a total of 48 young men and women who have been carefully screened for psychiatric and medical disorders. Subjects will be assigned to a yoga, relaxation exercise, or sleep hygiene treatment group. We anticipate that yoga practice will prove to be an effective treatment for insomnia which will yield significant improvements in sleep onset latency. We also anticipate that these improvements will be maintained at long-term follow up evaluation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
