Moderate Workouts Protect Against Flu

By Matt McMillen , ,


For years, scientists have been working to understand the effect of exercise on the body’s ability to fight infections. Now a review of 129 studies about exercise and the immune system suggests that regular, moderate workouts protect against viruses like colds and the flu. But intense workouts raise your risk. Here’s why: During exercise, your immune system sends its troops—the white blood cells—to protect areas under activity-induced stress, such as your lungs and skin. The more intense and frequent your workout, the longer it takes for those cells to resume defending against illness, leaving you less protected against infections.
