This study from the Sleep Disorders Center in Turkey provides strong evidence that a Tai Chi and Qigong program (three times per week for twelve weeks) can significantly improve breathing during sleep and improve the quality of sleep in patients with sleep apnea.
Fifty participants were equally randomized into an intervention group and a control group. The intervention group received Tai Chi and Qigong instruction for 1 hour, 3 times a week with self-practice on 2 additional days for 12 weeks. The control group received a home exercise program only, for 5 days/week for 12 weeks.
