UC Health is expanding its integrative medicine services and offering free classes and programs during March. Among these is sound therapy, which uses sound waves and vibrations to help with relaxation and to lower stress and anxiety. Participants believe these practices can also enhance a sense of spiritual well-being. Most sound therapy classes are low cost, but they are not usually covered by medical insurance plans. Researchers have found that sound vibration may reduce pain, including arthritis, menstrual pain, and pain after surgery and joint replacement.
