Yoga is increasingly popular in all age groups, and with this popularity have come a number of health and wellness claims. I feel that anything that moves your body, takes you away from the stresses of everyday life, and results in positive personal feelings is worth considering. And it is definitely worth doing if has no side effects and is relatively inexpensive. What about improvement in hard clinical biomarkers, however? The evidence here is less conclusive. An enthusiastic review article was released today in Diabetes & Metabolic Syndrome: Clinical Research & Reviews. The authors present data on improvements in both A1C and blood pressure, but when I track down the references they come from small studies that lack the usual rigor found in main stream journals. That being said, people can always check their own A1C and blood pressure to see if there is benefit, and yoga certainly is more attractive empirically and theoretically than any products being promoted by the nutraceutical industry.
