I used to be a big fan of all these studies of the brain and meditation using fMRI imaging and such. However, of late, I have also heard some serious questions about the methodology on many of these experiments, including questions about how they are interpreting data, the control groups used, the mishmash of various meditation techniques all thrown under the label of "meditation", the mix of beginners and experienced folks who are being tested, etc.
In June, 2007 the United States National Center for Complementary and Alternative Medicine (NCCAM) published an independent, peer-reviewed, meta-analysis of the state of meditation research, conducted by researchers at the University of Alberta Evidence-based Practice Center. The report reviewed 813 studies involving five broad categories of meditation: mantra meditation, mindfulness meditation, yoga, T'ai chi, and Qigong, and included all studies on adults through September 2005, with a particular focus on research pertaining to hypertension, cardiovascular disease, and substance abuse.
The report concluded, "Scientific research on meditation practices does not appear to have a common theoretical perspective and is characterized by poor methodological quality. Firm conclusions on the effects of meditation practices in healthcare cannot be drawn based on the available evidence. Future research on meditation practices must be more rigorous in the design and execution of studies and in the analysis and reporting of results." (p. 6) It noted that there is no theoretical explanation of health effects from meditation common to all meditation techniques.[54]
A version of this report subsequently published in the Journal of Alternative and Complementary Medicine stated that "Most clinical trials on meditation practices are generally characterized by poor methodological quality with significant threats to validity in every major quality domain assessed". This was the conclusion despite a statistically significant increase in quality of all reviewed meditation research, in general, over time between 1956–2005. Of the 400 clinical studies, 10% were found to be good quality. A call was made for rigorous study of meditation.[15] These authors also noted that this finding is not unique to the area of meditation research and that the quality of reporting is a frequent problem in other areas of complementary and alternative medicine (CAM) research and related therapy research domains.
Of more than 3,000 scientific studies that were found in a comprehensive search of 17 relevant databases, only about 4% had randomised controlled trials (RCTs), which are designed to exclude the placebo effect.[13] Reviews of these RCTs consistently find that meditation without a focus on developing "mental silence", an aspect often excluded from techniques used in Western society, does not give better results than simply relaxing, listening to music or taking a short nap. While those who practiced mental silence showed clinically and statistically significant improvements in work related stress, depressed feelings, asthma-control, and quality of life as compared to commonly used stress management programs.[35]
I often say that Zazen is very very good, but it will not fix a broken tooth. You need a dentist for that. It may make one profoundly content and truly at home and whole in one's life, but not so constantly "happy happy happy" that one feels non-stop ecstasy as if one just won the Powerball Lottery while breathing laughing gas 24 hours a day! So, one must be cautious about reading too much into the power of Zazen.
The key word often used by researchers/ teachers of mindfullness meditation seems to be 'adapted' - adapted from buddhist techniques of meditation.I have every respect for mindfullness training and how it can help people, but there's a bit of me that wants to say 'this really isn't anything much to do with Zen or buddhism in general'.
Zen feels to be a total way of life - not just centred on self - and the need to be stress free and relaxed - but 'other' centred, as a primary goal. There is also the fact that Zen is a spiritual practice. However - I'm sure a lot of people find their way to buddhism through mindfullness meditation,
(Here in the UK mindfullness meditation is now being proffered as the 'answer' to just about every medical condition and I do find that a bit concerning, as it is as much to do with politics and saving money as the true welfare of patients.)
I'm with you both. I said 'interesting' and meant just that. I have a healthy scepticism to all these 'scientiific comparisons. Zazen is what it is, if zazen helps with this & that then that's fine if it doesn't then that's fine also.
Did you hear where the 84 yr old lady who won the $600M Powerball was given a go ahead to advance in the wait line to buy her one-line easy pick winning ticket. I wonder if she sat zazen that morning?
I think these studies that point to potential benefits of meditation are no bad thing as it seems very helpful in the sphere of medicine and mental health and may encourage others to take up sitting as a spiritual practice. None of these mindfulness techniques suggest their use instead of medication but there is evidence that doing so can indeed reduce the intake of painkillers which is great. I had not heard of methodological problems but, as with all scientific studies, it is something that needs to be watched for.
Of course there is always the danger that people coming to Zen and other Buddhist paths from mindfulness will have certain utilitarian expectations of practice but who doesn't start sitting in the belief that it will cure most, if not all, ills? A couple of years of sitting tends to cure that! ;-)

Hey Andy,
I know that Shikantaza can work as a pain reliever, having "Zazen'd" my way through quite a few minor medical and dental procedures, and a couple of injuries that were quite painful like a broken bone. One can find a center, and step away or through much of the pain.
However, I still take the novacaine and such as soon as it is offered.
There may be some minor health benefits of Zazen, but I often say that Zazen will not cure your cancer. You have to seek a doctor and chemotherapy to try to do that.
So what good is Zazen?
Well, strange as it sounds, Zazen will allow one to be wholly "okay" and "at home" with one's cancer (or bad tooth or broken arm). It will allow one to "go with the flow" of the chemotherapy, even the pain.
That is so even while it is not "okay" and not fun, and quite scary. One will accept even as one does not accept!
Shikantaza allows one to experience life in such way ... okay even while not okay.
I often tell the story of a friend of mine who did have cancer and received treatment for it. She said that the years of Zazen Practice allowed her to accept and "be one" with it all ... even as she was puting up the good fight for a cure, and went through quite a rough time, was sometimes scared or depressed. Zen Practice even allowed her to be "okay" with the quite natural stages of being scared and depressed ... not afraid of being afraid!
Fighting the good fight to stay alive ... and beyond "life and death" at once. Afraid ... and beyond all fear at once.
"The often painful posture associated with Zen meditation may lead to thicker cortex and lower pain sensitivity"
Thicker cortex? The "thickening" actually seems to be occurring at the other end of the spine. Or, perhaps the nerves in my butt are just growing numb.
Even if our posture was meant to be painful I would think that that would only lead to lower pain sensitivity and strength where the posture is painful. Sort of like conditioning does in some martial arts. Or it would just cause injury. The article didn't say how the person was sitting, full lotus, half, Burmese, etc,.
If sitting makes me more pain tolerant, fantastic! If it doesn't, fantastic!
However, I still take the novacaine and such as soon as it is offered.
Indeed. It would be foolish to do otherwise. I have found the greatest benefit of my meditation practice to come from acceptance of illness and loss of the ability to work and do other things. The ability to deal with moderate pain is useful but not nearly so much as being able to sit with whatever comes up emotionally. Or to sit with the inability to cope with it - as you say, okay when not okay.
Of course there is always the danger that people coming to Zen and other Buddhist paths from mindfulness will have certain utilitarian expectations of practice but who doesn't start sitting in the belief that it will cure most, if not all, ills? A couple of years of sitting tends to cure that! ;-)
Thanks Andy - that made me smile So very true of myself a while back.
The mindfullness book that set me off on this path is 'Heal Thyself' by Saki Santorelli who works at a medical centre for chronic illness. It was such a relief to have it authenticated that it is fine to just be with illness and chronic pain and not try to force change - just to be with what is.
Well, I'm also suspicious of "studies" like this, but I will say, I wish I would have known about zazen before going through 37 hrs of excrutiating back labour and an emergency c-section before my first child was born!! I would have been willing to try anything to get rid of some of that pain, hammer on head did cross my mind several times during the marathon!!
