Another Reason to Exercise: Boost Your Immune System

We're nearing the end of flu season and heading into allergy season, but that doesn't mean we should get complacent about fighting off illness. Since I am always looking for new reasons to exercise and new ways to avoid getting sick, I was excited to find this research suggesting that consistent exercise can boost your immune system.


Moderate exercise temporarily increases your body's production of macrophages, the cells designed to fend off bacteria, and allows them to travel more efficiently through the body. Though these are temporary responses to working out, new research suggests that the more often you exercise, the more permanent the health benefits become. According to Dr. David Nieman of Appalachian State University, moderate exercise on a regular basis also strengthens your immune system in the long run.

But for super-serious athletes like marathoners, exercise can actually make the body more susceptible to illness, so be sure to give yourself plenty of recovery days if you're training for a big event.

Do you exercise daily? If so, do you think it helps you avoid getting sick?
