An 8-week mindfulness meditation training program for healthy employees increased left-sided anterior brain activation, a pattern linked to positive emotion, and boosted antibody titers after an influenza vaccine compared with a wait-list control group. The magnitude of the brain activation increase predicted the size of the antibody response. These results indicate that a brief meditation intervention can measurably alter brain and immune function.
Over the past two decades, mindfulness-based therapies have become widely accepted in clinical practice and popular culture, but with that acceptance has come growing criticism. Critics worry that stripping mindfulness from its original ethical frameworks turns it into a commodity for goals like weight loss, workplace productivity, or better school performance—uses it was never intended to serve. Yet the clinical and religious communities have long used meditation pragmatically for healing. This essay steps back to ask why these concerns are surfacing now, aiming to understand the historical roots of the current discontent rather than simply joining the critique.
