Cancer can be a devastating disease that saps energy often due to radiation and chemotherapy. Researchers at the University of Rochester Medical Center in New York assigned more than 400 cancer survivors to one of two groups.
Most had been treated with chemotherapy for breast cancer. The first group did gentle Hatha yoga and restorative yoga twice a week for a month. The other group did not engage in such activity. The individuals who did yoga were able to cut back on sleeping pills and slept better. Yoga also increased their energy levels and improved their quality of life.
