In this article, meditation researchers offer evidence, both empirical and narrative, to support the preventative effects of mindfulness and meditation. In particular, these contemplative practices have a preventative effect on anxiety, depression, stress, and other psychological health issues. One researcher, recently retired Professor Mark Williams of Oxford University, notes, however, that "a lot of people think it [meditation and mindfulness] will cure everything. But we know there is nothing that cures everything."
