Meditation has been practised for centuries by various religious traditions to have a break from mundane pressures and to ease your worries. Lately, meditation has become increasingly popular among non-religious people as a way to focus your mind, and cope with stress and anxiety. The article "Does meditation actually work? This is what the science says" by Judhijit Bhattacharjee on National Geographic explores how some scientific studies are trying to shed light on the benefits of meditation for mental health. This article is conceptually complex at times so, it is suitable for C1 students, who will encounter formal words like: to settle down, a [floor] mat, a worship [room], a deity, a throne, a [prayer] bead, to chant, a whisper, to enhance, [to be] rooted, a quest, enlightenment, to conduct [a study], to trigger [anxiety], to glow, mild, to shed [a fearful response], a [brain] scan, an MRI scan, to rely on [someting], a headband, rife [with stress], to strive [to apply it], a wispy [beard], assault, wrestling, flustered.
Many U.S. and British schools offer mindfulness programmes and apps to help kids concentrate and overcome negative emotions. You can listen to NPR's report "To help these school kids deal with trauma, mindfulness lessons over the loudspeaker" (6:34) by Pien Huang to learn more about how mindfulness practice is implemented in a Florida public school. This radio article can be accessible to B2+ students with the script and C1 learners without it, who will find interesting colloquial phrasal verbs and expressions like: loudspeaker, to cope with, packed, to hang out, to catch up, [apple] strudel, a wrapper, a [banana] peel, to line [the kids] up, to assemble, [your body is] still, to focus, homelessness, increasingly [popular], to shrink [the brain], a trait, to enhance [well-being], to show up [in school], forgiveness, to fidget, to let [that] go, to relieve [stress], to take it out on [somebody], an assignment, to draw on [something], to distill [the teachings], to tune into [sounds], to handle [sense awareness], to be dragged [around] [by their thoughts], [to feel] empowered, to scale up, a [shark] fin, to shape up [well], to hug, to high-five, to applaud, to have a hard time.
