Some years ago, when Nina and I were working on a series of yoga classes for stress management, I read the book The Relaxation Response by Dr. Herbert Benson, and an interesting finding from the work he did has stuck with me. He noted that his blood pressure patients who meditated regularly not only saw improvements in their blood pressure readings, but they also had certain substances in the blood stream that increased or decreased. One of those substances was lactate, or lactic acid, which is a byproduct of cells using sugar or glucose for fuel. It had already been noted back in the 60s that folks with anxiety disorders often had elevated levels of lactate in their bloodstream compared to individuals without anxiety. Since meditation seemed to lower lactate levels, it seemed like a great potential treatment.
