according to a recent study in Medicine & Science in Sports & Exercise, which investigated the number of common colds in more than 500 people of varying activity levels. For one year, researchers tracked these individuals for the number of upper-respiratory tract infections and total levels of activity.
Findings revealed the most active individuals in the study suffered an average of 23% fewer colds per year than the least active people. In the fall, the difference was the most noticeable, with 32% less risk for a cold in the most active group. Forty percent of all colds in this study were reported in the fall.
