Laura Calandrino hasnâ??t had a cold or the flu this winter. George Hagenauer has had one cold but thinks he fought off a few others. The Madison-area residents are among 154 people in a UW-Madison study, which started in September, asking if exercise or meditation can ward off colds and the flu. Researchers are looking at whether either activity makes the immune system better able to fight respiratory infections, according to Dr. Bruce Barrett, a UW Health family physician heading up the research.
