Exercise and meditation are nothing to sneeze at. They are great weapons against the common cold and other acute respiratory infections. Simply following those disciplines can reduce how many colds you get and limit how bad the illness becomes and how many days of work you might miss. Researchers at the University of Wisconsin-Madison studied 149 people, 50 years and older. After eight weeks of training, participants meditated daily, exercised regularly or did not do either activity for the remainder of the winter season. Study results found that those in the exercise group reduced the number of colds by 29% and the meditation group by a whopping 33%, compared to those that did neither. Duration and severity of the cold were also cut dramatically.
