Long-term meditation practice is also associated with a physical reduction in the size of the amygdala region of the brain (the "fight or flight" center). This leads to permanent lowering of baseline anxiety. At the cellular level, long-term meditation appears to slow down the "clocks" inside our cells. Telomeres are the protective caps at the end of our chromosomes.
Short telomeres are markers of aging and disease. On that subject, a study published in Psychoneuroendocrinology showed that long-term meditators (averaging 5+ years) have significantly higher telomerase activity. This is the enzyme that repairs telomeres, suggesting that daily meditation may actually slow cellular aging and increase longevity.
In addition, our brains have a "Default Mode Network" (DMN) that is active when we are not doing anything specific, like "mind-wandering" and worrying about the past/future. A Yale University study found that in experienced meditators (10+ years), the DMN is permanently transformed.They don't just "quiet" their minds during meditation; their brains have a new "default" state where mind-wandering is reduced, leading to higher levels of daily happiness and presence. This said, some of the most extreme results come from the University of Wisconsin-Madison, which studied intense meditators (10,000 to 50,000 hours of practice).
These showed massive increases in Gamma wave activity—the highest frequency brain waves associated with peak concentration, "flow" states, and feelings of universal compassion. Crucially, these high levels of Gamma activity stayed even when they were not meditating, suggesting that after 10 years, the "state" of meditation becomes a permanent "trait" of the person.
Clearly, the more years and minutes we put into meditation, the more our brain changes for the best. Pretty cool! Do you need more incentive?
