DEAR DOCTOR K: I can't turn around without hearing about mindfulness these days. Is it just for stress reduction, or is there more to it?
DEAR READER: Mindfulness may have started out as a meditation technique. But now it is being used for everything from boosting happiness to treating high blood pressure. It's been shown to help treat depression and anxiety and improve sleep quality. And it's being studied as a complementary therapy for cancer, stroke, multiple sclerosis and pain.
