We know you don't need a study to convince you of the mind-quieting potential of meditation (didn't we all read Eat Pray Love?), but this one's pretty impressive: A group of Boston University researchers analyzed the results of 39 studies with 1,140 total participants to assess how effective mindfulness-based therapy really was (they admitted in their conclusion that they were initially skeptical). They found that this type of meditation is legitimately effective in treating not just anxiety, mood disorders and depression, but also cancer and other psychiatric and medical conditions. The icing on the cake: just a few minutes will do the trick. And a study published in the Proceedings of the National Academy of Sciences found that meditation can lower stress in less than a week.
