Last December in its Healthland section on the web, Time Magazine published an interesting article entitled “Explaining Why Meditators May Live Longer” by Maia Szalavitz. Below we excerpt some of the more interesting sections of the article:
“The image of the ancient but youthful-looking sage meditating on a mountaintop might be closer to reality than you think, according to a new study that found that after a three-month stay at a meditation retreat, people showed higher levels of an enzyme associated with longevity.
…Researchers led by Tonya Jacobs of the University of California-Davis compared 30 participants at a meditation retreat held at the Shambhala Mountain Center in Colorado with matched controls on a waiting list for the retreat. Participants meditated six hours per day for three months. Their meditation centered on mindfulness — for instance, focusing solely on breathing, in the moment — and on lovingkindness and enhancing compassion towards others.
After the three-month intervention, researchers found that the meditators had on average about 30% more activity of the enzyme telomerase than the controls did. Telomerase is responsible for repairing telomeres, the structures located on the ends chromosomes, which, like the plastic aglets at the tips of shoelaces, prevent the chromosome from unraveling. Each time a cell reproduces, its telomeres become shorter and less effective at protecting the chromosome — this, researchers believe, is a cause of aging. As the chromosome becomes more and more vulnerable, cell copying becomes sloppier and eventually stops when the telomeres disintegrate completely. Telomerase can mitigate — and possibly stop — cell aging.
“Something about being on a retreat for three months changed the [amount of] telomerase in the retreat group,” says Elizabeth Blackburn, a study author who has won a Nobel Prize for her previous work on telomerase…. “A lot of things happened during the retreat. But the interesting thing was that the changes we saw tracked quantifiably with the change in people’s psychological well-being and outlook.”
In other words, people with higher levels of telomerase also showed more increases in psychological improvement.
…”It’s a very good study with interesting results in terms of health implications,” says Alan Marlatt, a professor of psychology at the University of Washington who has studied meditation for decades but was not associated with this research.
…In a study published a few years ago in Lancet Oncology, researchers compared 30 men before and after adopting lifestyle changes following a diagnosis of low-risk prostate cancer. The patients started meditating, switched to a healthy plant-based diet, exercised and attended a support group. Like the new study, the Lancet Oncology paper found increases in telomerase linked with reduced psychological distress.”
While, of course, this is not the purpose of meditation, it is interesting to note that the quest for the Divine has its positive side effects.
