Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Effects of gentle yoga on sleep

    Researchers at the University of Washington, in Seattle, studied changes in sleep in older women with osteoarthritis.

    First, the details.

    • 14 women with osteoarthritis and symptoms of insomnia completed an 8-week yoga program that included 75-minute weekly classes and 20 minutes of nightly home practice.
    • Symptom questionnaires, sleep diaries, and 1 week of wrist actigraphy were completed.
    • Actigraphic measures estimate sleep amounts and sleep continuity in patients with sleep disorders.

    And, the results.

    • 13 women completed the study.
    • The Insomnia Severity Index and diary-reported sleep onset latency (time before falling asleep), sleep efficiency (the ratio of time spent asleep to time spent in bed), and number of nights with insomnia were significantly improved.
    • Other sleep outcomes (Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, diary-reported total sleep time and wake after sleep onset) showed improvement, but these were not statistically significant.
      • Actigraphic sleep outcomes were not significantly changed.

    The bottom line?

    The authors concluded, “This study supports the feasibility and acceptability of a standardized evening yoga practice for middle-aged to older women with osteoarthritis.”

    Past studies of yoga in women with insomnia have been of low quality.

    This was a preliminary study, and it will require confirmation of the results in future research.
