Tibetan Singing Bowls
Believed to promote relaxation, relieve stress, and produce other healing effects. Despite their name, the bowls may have originated not in Tibet but in China in the 16th century BCE. In the last few decades, increased interest in Tibet may have helped popularize these bowls, and now they can be found in various countries all over the world.
Purported benefits include improving sleep, reducing depression, relieving pain, and increasing immunity.
