How Meditation Can Change Your Brain

You know meditation is good for you, but did you know that it actually changes the brain in positive ways? Meditation is increasingly being used to overcome addiction because addiction itself is a negative changing of the brain, a chemical addiction. If meditation can alter the brain for the positive, addiction therapy can include more holistic, long-lasting measures. But how exactly does meditation shift the brain?

Neurological Benefits

Meditation comes with a host of neurological benefits, with studies showing that it changes the volume of gray matter as well as minimizing the activity within the “me” hubs of the brain. One study out of UCLA showcased how those who meditated for several years had brains better preserved than those who didn’t. Participants had to have meditated for at least 20 years and were found to have more grey matter in all parts of the brain. Lead researcher Florian Kurth says, “We expected rather small and distinct effects located in some regions that had previously been associated with meditating—instead, what we actually observed was a widespread effect of meditation that encompassed regions throughout the entire brain.”

Yale University released a study that highlighted how meditation retards the brain’s “me” center, otherwise known as the default mode network (DMN). If you find yourself regularly having your mind wander and experiencing selfish thoughts, DMN is at fault. It’s active when we’re not focusing on anything and when we allow our minds to wander. “Mind-wanderers” are considered less happy than others, prone to brooding and worrying. Meditation has a quieting effect on the brain, slowing down this area and offering better concentration.

Anxiety and Depression

Another study out of Johns Hopkins considered mindfulness and meditation to treat anxiety and depression. Researchers found that meditation had the ability to minimize depression, pain, and anxiety symptoms. According to lead researcher Madhav Goyal, those who take low doses of antidepressants experienced just as much help when prescribed meditation. “A lot of people have this idea that meditation means sitting down and doing nothing. That’s not true,” says Goyal. “Meditation is an active training of the mind to increase awareness, and different meditation programs approach this in different ways.”

Harvard researcher Sara Lazar discovered that medication can increase volume in a number of areas in the brain. After eight weeks of a mindfulness-based stress reduction study, it was found that participants had an increase in the cortical thickness throughout the hippocampus, the part of the brain in charge of memory. Emotional regulation parts of the brain and self-referential processing units also enjoyed a boost in volume. Lazar also found that parts of the brain volume decreased, particularly in the amygdala, the part of the brain responsible for stress, pain, and anxiety. Through meditation, Lazar’s team discovered that the changes in the brain also led to changes in how the participants actually felt.

Concentration

Another study considered the link between meditation and attention spans/concentration. A lot of people struggle with concentration, with Google researchers saying that westerners have worse attention spans than goldfish. However, a study found that in just two weeks of meditation training, participants had better memory and focus. The verbal reasoning part of the GRE was used to gauge changes. Their average scores were so much better; it equated to 16 percentile points (something college and high school students would be thrilled to achieve). Focusing attention is at the heart of any meditation program, so the natural increase in cognitive skills is an added bonus.

Social Anxiety

Research studies linking meditation and social anxiety are also well-founded. The mindfulness-based stress reduction (MBSR) movement, headed by the University of Massachusetts’ Center for Mindfulness and director Jon Kabat-Zinn, claims that meditation is a key factor in reducing overall stress levels both mentally and physically. The studies have also reported that in an eight-week course, the benefits are evident even years later (when participants didn’t continue beyond those eight weeks).

Meditation is a true game changer and one of the simplest ways you can alter your brain for the better. We have so much stimulation directed at us around the clock, it can easily overwhelm the body. Meditation is a way to get back to your center, quiet the mind, and let the brain do a little recovery work. It needs rest and proper workouts, too, both of which meditation can provide. A healthy brain is a part of a healthy body.
