A Jog a Day Keeps the Doctor Away - Exercise and Inmune System performance

According to a study by Dr. David Neiman, director of the Human Performance Laboratory at Appalachian State University in North Carolina, people who exercise five or more times a week experience fewer and less-severe colds than those who exercise once a week or not at all. The researchers observed and recorded the respiratory health of 1,000 people between the ages of 18 and 85 for three months in fall and winter and found that those who worked out five or more times a week experienced 43-46% shorter-lasting cold symptoms that were also 41% less severe. Further testing showed that exercising stimulates the spread of immune cells throughout the body, suggesting that the more a person exercises, the more often immune cells will be activated. “It’s the frequency, and getting the cells moving,” Neiman explains, “That’s what provides the top-level protection of the body.” The study, published November 1st in the British Medical Journal, is just one of many that advocates there is a link between exercise and a boosted immune system. This has led Dr. Neiman to believe, “From animal data to multiple human trials, we’ve kind of reached a point now where there’s enough evidence that this has to be real.”
