By now, everyone knows that mindfulness meditation is good for you—but what’s still surprising scientists is just how quickly it works. Ten minutes of meditation won’t make you a better mutlitasker—there’s no such thing, as psychologist and science journalist Daniel Goleman explains—but it will make you more adept at switching tasks and returning to a deep level of concentration more quickly after a distraction. Every time you practice meditation, you’re strengthening the neural circuitry for focus and training your brain away from mind-wandering. Beyond the need to concentrate for work, pleasure, or to overcome negative emotion, mindfulness meditation can also help to manage disorders like PTSD, anxiety, and Attention Deficit Disorder (ADD).
