Yoga Aids Sleep Quality
Often, cancer survivors experience poor sleep quality as a result of cancer therapy. Karen M. Mustian, from the University of Rochester Medical Center (New York, USA), and colleagues studied 410 cancer survivors, median age 54 years, suffering from moderate or greater sleep disruption between 2 and 24 months after surgery, chemotherapy, and/or radiation therapy, with each randomly assigned to standard care or standard care plus a 4-week intervention of twice-weekly 75-minute, low-intensity yoga sessions. The rsearchers observed that those in the yoga program decreased their sleep medication use by 21%, as compared to the participants in standard care only. As well, the yoga group demonstrated significant improvements in sleep latency, sleep duration, sleep efficiency, sleep disturbances, subjective sleep quality, and daytime dysfunction during the intervention period. The study authors submit that: “Yoga … is a useful treatment for improving sleep quality and reducing sleep medication use among cancer survivors.”
