Fight Fatigue with Exercise

The last thing you may feel like doing when you’re tired is exercising. Many studies show that physical activity boosts energy levels.

“Exercise has consistently been linked to improved vigor and overall quality of life,” says Kerry J. Stewart, professor of medicine and director of clinical and research exercise physiology at Johns Hopkins University School of Medicine. “People who become active have a greater sense of self-confidence. But exercise also improves the working efficiency of your heart, lungs and muscles,” Stewart says. “That’s the equivalent of improving the fuel efficiency of a car. It gives you more energy for any kind of activity.”
