Meditate that Cold Away

From the pages of Scientific American. Meditate That Cold Away. Practicing meditation or exercising might make you sick less often. To blunt your next cold, try meditating or exercising now. A new study from the University of Wisconsin-Madison found that adults who practiced mindful meditation or moderately intense exercise for 8 weeks suffered less from seasonal ailments during the following winter than those who did not exercise or meditate. The study appeared in the July issue of Annals of Family Medicine. Researchers recruited about 150 participants, 80 percent of them women and all older than 50, and randomly assigned them to three groups. One group was trained for eight weeks in mindful meditation; another did eight weeks of brisk walking or jogging under the supervision of trainers. The control group did neither. The researchers then monitored the respiratory health of the volunteers with biweekly telephone calls and laboratory visits from September through May—but they did not attempt to find out whether the subjects continued meditating or exercising after the initial eight-week training period. Participants who had meditated missed 76 percent fewer days of work from September through May than did the control subjects. Those who had exercised missed 48 percent fewer days during this period. The severity of the colds also differed between the two groups. Those who had exercised or meditated suffered for an average of five days; colds of participants in the control group lasted eight. Lab tests confirmed that the self-reported length of colds correlated with the level of antibodies in the body, which is a biomarker for the presence of a virus. “I think the big news is that mindfulness meditation training appears to have worked” in preventing or reducing the length of colds, says Bruce Barrett of the department of family medicine. He cautions, however, that the findings are preliminary. The author is Harvey Black. Reproduced with permission. Copyright 2012 Scientific American, a division of Nature America, Inc.
