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.
A pilot study tested a modified Mindfulness Based Stress Reduction (MBSR) program as a smoking cessation intervention. Eighteen participants attended weekly mindfulness sessions and attempted to quit smoking in week seven without medication. Six weeks after the quit day, 56% (10 of 18) had biologically confirmed seven-day smoking abstinence. Greater meditation practice was linked to higher abstinence rates and lower stress and emotional distress. The findings suggest mindfulness training may help with smoking cessation and merits further research in a larger controlled trial.
