"People who exercise regularly are less likely to get a cold, researchers say. A study of 1,000 people found that staying active nearly halved the odds of catching cold viruses and, failing that, made the infection less severe.

This latest research suggests there are lifestyle choices you can make to improve your odds of either avoiding them, or suffering too badly from them
