According to a new study from Karen Mustian at the University of Rochester Medical Center, cancer survivors should try yoga to sleep better and boost their energy levels. In the study, researchers randomly assigned over 400 cancer survivors, most of whom had been treated with chemotherapy for breast cancer, to two different groups. One did Hatha and restorative yoga, including postures, breathing and mindfulness exercises, twice a week for a month, the BBC reports. The other group was only monitored under standard practice. Those who did yoga could reduce sleeping pills, and saw a 22 per cent increase in sleep quality, nearly twice the improvement of survivors who didn’t do the exercises. It also cut fatigue by close to half and boosted quality of life.
