Why It Matters to You

Just about every body comes equipped with the genetic material it needs to deal optimally with the physical challenges of daily life, and the degree to which you can maintain your mental equilibrium has a real impact on your body’s ability to access those genetic resources. While habits of mind can be challenging to break, deliberate activities like meditation (see the following studies) can help you refashion your neural pathways to support less reactive thought patterns.


Meditation Rewires Your Brain

Meditation and other forms of relaxation and mindfulness not only change your immediate state of mind (and, correspondingly, your biochemical stress level and gene expression), they also can alter the very structure of your brain. Neuropsychologist Rick Hanson, PhD, cofounder of the San Francisco–based Wellspring Institute for Neuroscience and Contemplative Wisdom, has extensively studied the effect of meditation on the brain, with a particular focus on how neuroplasticity allows for permanent changes for the better in your gray matter.

The Research

“Of all the mental trainings — affirmations, psychotherapy, positive thinking, yoga — the one that has been far and away the most studied, in terms of effects on the brain, is meditation,” Hanson says. Some of the most prominent research has come from the collaboration between French-born Buddhist monk and author Matthieu Ricard and University of Wisconsin–Madison neuroscientist Richard Davidson, PhD. Their studies have shown that a high ratio of activity in the left prefrontal areas of the brain can mark either a fleeting positive mood or a more ingrained positive outlook.

Brain-imaging tests have shown that Ricard and other veteran Buddhist meditators demonstrate initial heightened activity in this region, along with a rapid ability to recover from negative responses brought on by frightening images shown to them by researchers. This suggests that their long-term meditation practice has helped build brains that are able to not just enjoy but sustain a sense of positive well-being, even in stressful moments.

Why It Matters to You

“Stimulating areas of the brain that handle positive emotions strengthens those neural networks, just as working muscles strengthens them,” Hanson says, repeating one of the basic premises of neuroplasticity. The inverse is also true, he explains: “If you routinely think about things that make you feel mad or wounded, you are sensitizing and strengthening the amygdala, which is primed to respond to negative experiences. So it will become more reactive, and you will get more upset more easily in the future.”

By contrast, meditative practices stimulate the anterior cingulate cortex, the part of the brain’s outermost layer that controls attention (this is how meditation can lead to greater mindfulness, Hanson explains), as well as the insula, which controls interoception — the internal awareness of one’s own body. “Being in tune with your body via interoception keeps you from damaging it when you exercise,” Hanson says, “as well as building that pleasant, simple sense of being ‘in your body.’” Another plus of a strong insula is an increased sensitivity to “gut feelings” and intuitions and greater empathy with others.

Perhaps best of all, meditation develops the circuitry in the left prefrontal cortex, where the unruffled monks showed so much activity. “That’s an area that dampens negative emotion, so you don’t get so rattled by anger or fear, shame or sorrow,” Hanson says.

“Deciding to be mindful can alter your brain so that being mindful is easier and more natural,” he explains. “In other words, you can use your mind to change your brain to affect your mind.”
