Fact: Feeling “run down” makes you get sick
When we fall ill, it seems as though the first thing we point to is feeling tired and generally worn out. “There is some validity to that,” says Dr. Mirwaldt, “especially if you haven’t been sleeping or eating well.” But you still need an infectious agent—almost always a virus—to actually become sick. The best defense, says Dr. Mirwaldt, is to wash your hands and avoid sharing drinks with other people.
To avoid that “run-down” feeling, particularly during cold and flu season, make sure that you’re eating plenty of healthy, immunity-boosting foods, getting at least half an hour of exercise every day, and leaving yourself enough time to get a good night’s rest.
