Meditation May Cut Heart Disease Death
Path to Enlightenment Could Lower Risk of Dying in People at Risk for High Blood Pressure
My Meditation Is Better Than Yours
There are many different versions of meditation, but is any one better than another? It depends on who you ask.
Schneider says the new findings offer powerful evidence that TM conveys mortality advantages that other forms of meditation don't. But other experts contacted by WebMD, including Vroom, are skeptical.
One of the studies included in the analysis compared four types of intervention -- TM, another popular meditation technique known as mindfulness meditation, generic instruction in meditation, and educational instruction with no meditation.
Seventy-seven elderly, white adults were included in that study, led by TM advocate Charles N. Alexander, PhD, who died in 1998. The other study was led by Schneider and included 125 blacks who were either taught TM or were given health education without meditation. The original intent of both the studies was to determine if meditation could lower blood pressure or risk or developing high blood pressure in the future. The average follow-up during the study was eight years.
The mortality analysis is published in the May issue of The American Journal of Cardiology.
Which Works Best?
Schneider dismisses the idea that the original studies and the new analysis were biased in favor of the TM approach.
"This study showed what it showed, and it was evidence-based," Schneider says. "This is the first time that a particular meditation technique has been shown to reduce death rates from all causes and from cardiovascular disease."
But Harvard psychologist Ellen Langer, PhD, who has written three books on the "mindfulness" technique, says it is unlikely that one meditation conveys more health benefits than another.
"Rather than saying that something doesn't work, I would say that there are data out there to suggest that most of these techniques do work," she says. "There may be as many forms of meditation out there as there are flavors of ice cream. Whether one is better than the other depends on individual taste, but overall they are all basically going to give you some of the sweetness that you desire."
