This study by researchers at the Department of Human Development and Psychological Counseling, Appalachian State University, Boone, North Carolina, "examined whether mindfulness increased through participation in movement-based courses and whether changes in self-regulatory self-efficacy, mood, and perceived stress mediated the relationship between increased mindfulness and better sleep."
Participants included 166 college students participating in 15 week classes in Pilates, Taiji quan, or GYROKINESIS. At intervals during the semester, participants completed measures of mindfulness, self-regulatory self-efficacy, mood, perceived stress, and sleep quality.
The study demonstrated an increase in total mindfulness scores and mindfulness subscales overall. "Greater changes in mindfulness were directly related to better sleep quality at the end of the semester after adjusting for sleep disturbance at the beginning." Researchers concluded that "Movement-based courses can increase mindfulness. Increased mindfulness accounts for changes in mood and perceived stress, which explain, in part, improved sleep quality."
