Harvard Medical School researchers working at the Massachusetts General Hospital have determined that meditation can improve brain health. The researchers studied 16 volunteers that took part in an eight-week mindfulness meditation study at the University of Massachusetts Center for Mindfulness.

The participants conducted mindfulness meditation exercises for an average of 27 minutes a day. Before and after the trial, the subjects were given tests and magnetic resonance imaging of their brains. The researchers found that the practice of mindfulness meditation resulted in increased gray matter density in the hippocampus of the brain, an area associated with increased memory and learning capacity, plus a greater sense of compassion and introspection.
