Multiple studies suggest that meditating — focusing intently and quietly on the present for set periods of time — can help lessen feelings of depression and anxiety. Research in long term meditators — Buddhist monks, for example — shows that these peoples’ brains have well-developed areas that could be linked to heightened awareness and emotional control. While it's possible that people with such brains might be more likely to meditate in the first place, other studies do show that people who complete a meditation program tend to show brain changes linked with self-awareness, perspective, and memory.
