How mindfulness training affects health
Carnegie Mellon University's J David Creswell—whose cutting-edge work has shown how mindfulness meditation reduces loneliness in older adults and alleviates stress—and his graduate student Emily Lindsay have developed a model suggesting that mindfulness influences health via stress reduction pathways.
Their work, published in Current Directions in Psychological Science, describes the biological pathways linking mindfulness training with reduced stress and stress-related disease outcomes.
"If mindfulness training is improving people's health, how does it get under the skin to affect all kinds of outcomes?" asked Creswell, associate professor of psychology in CMU's Dietrich College of Humanities and Social Sciences. "We offer one of the first evidence-based biological accounts of mindfulness training, stress reduction and health."
When an individual experiences stress, activity in the prefrontal cortex—responsible for conscious thinking and planning—decreases, while activity in the amygdala, hypothalamus and anterior cingulate cortex—regions that quickly activate the body's stress response—increases.
Studies have suggested that mindfulness reverses these patterns during stress; it increases prefrontal activity, which can regulate and turn down the biological stress response.
Excessive activation of the biological stress response increases the risk of diseases impacted by stress (like depression, HIV and heart disease). By reducing individuals' experiences of stress, mindfulness may help regulate the physical stress response and ultimately reduce the risk and severity of stress-related diseases.
Creswell believes by understanding how mindfulness training affects different diseases and disorders, researchers will be able to develop better interventions, know when certain treatments will work most effectively and identify people likely to benefit from mindfulness training.
As the birthplace of artificial intelligence and cognitive psychology, Carnegie Mellon has been a leader in the study of brain and behaviour for more than 50 years. The university has created some of the first cognitive tutors, helped to develop the Jeopardy-winning Watson, founded a groundbreaking doctoral programme in neural computation, and completed cutting-edge work in understanding the genetics of autism.

What is mindfulness training?
Mindfulness Based Stress Reduction (MBSR) brings together mindfulness meditation and yoga. It is an eight-week intensive training in mindfulness meditation, based on ancient healing practices, which meets weekly.
It cultivates greater awareness of the unity of mind and body, as well as of the ways the unconscious thoughts, feelings, and behaviours can undermine emotional, physical, and spiritual health. The mind is known to be a factor in stress and stress-related disorders, and meditation has been shown to positively effect a range of autonomic physiological processes, such as lowering blood pressure and reducing overall arousal and emotional reactivity.
The MBSR programme started in the Stress Reduction Clinic at the University of Massachusetts Medical Center in 1979 and is now offered in over 200 medical centers, hospitals, and clinics around the world, including some of the leading integrative medical centers such as the Scripps Center for Integrative Medicine, the Duke Center for Integrative Medicine, and the Jefferson-Myrna Brind Center for Integrative Medicine.
