The headline was sensationalized, as most headlines, tweets and Facebook posts are these days, and reads “Harvard Unveils MRI Study Proving Meditation Literally Rebuilds The Brain’s Gray Matter In 8 Weeks.”

An 8 week rebuild sounds great. As does “lose 10 pounds in 2 weeks” and “earn $1000 a week at home by surfing the Internet.” So, I’m skeptical. But it has that Harvard piece of credibility, so I read on.

Test subjects taking part in an 8-week program of mindfulness meditation showed results that astonished even the most experienced neuroscientists at Harvard University.  The study was led by a Harvard-affiliated team of researchers based at Massachusetts General Hospital, and the team’s MRI scans documented for the very first time in medical history how meditation produced massive changes inside the brain’s gray matter.

Not really even hardcore meditation but 27 minutes a day of mindfulness exercises was “all it took to stimulate a major increase in gray matter density in the hippocampus, the part of the brain associated with self-awareness, compassion, and introspection.”

And the participants self-reported a reduction in stress that “correlated with decreased gray-matter density in the amygdala, which is known to play an important role in anxiety and stress. None of these changes were seen in the control group, indicating that they had not resulted merely from the passage of time.”

Sine I already do some meditation and mindfulness activities almost every day, I suppose I’ve already reaped the benefits as much as possible. Still, the past few weeks have been very stressful and the next month or so looks to be even more so. I guess that being more mindful of my mindfulness and having a daily practice for more than a half hour might be even better.  And a hourlong walk in the woods seems to do a lot of good.
