More than 5 million deaths a year are attributable to tobacco smoking, but attempts to help people either quit or reduce their smoking often fail, perhaps in part because the intention to quit activates brain networks related to craving. We recruited participants interested in general stress reduction and randomly assigned them to meditation training or a relaxation training control. Among smokers, 2 wk of meditation training (5 h in total) produced a significant reduction in smoking of 60%; no reduction was found in the relaxation control. Resting-state brain scans showed increased activity for the meditation group in the anterior cingulate and prefrontal cortex, brain areas related to self-control. These results suggest that brief meditation training improves self-control capacity and reduces smoking.
每年有超过 500 万人的死亡归因于吸烟，但帮助人们戒烟或减少吸烟的尝试往往失败，部分原因可能是戒烟的意图激活了与渴望相关的大脑网络。我们招募了对一般压力减轻感兴趣的参与者，并将他们随机分配到冥想训练或放松训练对照组中。在吸烟者中，冥想训练（总共 5 小时）持续 2 周后，吸烟量显著减少了 60%；而在放松对照组中没有发现减少。静息状态下的大脑扫描显示，冥想组的前扣带和前额叶皮层活动增加，这些大脑区域与自我控制有关。这些结果表明，短暂的冥想训练可以提高自我控制能力并减少吸烟。
