Feeling Blah, Anxious or Depressed…Regular Exercise will Improve your Symptoms
Depression has been ranked as the leading cause of disability in the United States, with over $40 billion being spent each year on lost work productivity and medical treatment related to this illness. One in 10 adults in the United States struggles with depression, and antidepressant medications are a common way to treat the condition. However, pills aren’t the only solution. Research shows that exercise is also an effective treatment. “For some people it works as well as antidepressants, although exercise alone isn’t enough for someone with severe depression,” says Dr. -Michael Craig Miller, assistant professor of psychiatry at Harvard Medical School.
When you have depression or anxiety, exercise often seems like the last thing you want to do. But once you get motivated, exercise can make a big difference. Research on depression, anxiety and exercise shows that the psychological and physical benefits of exercise can also help improve mood and reduce anxiety. In one 2005 study conducted by researchers at the University of Texas Southwestern Medical Center, 30 minutes of moderately intense exercise five days a week reduced symptoms of depression by nearly half after 12 weeks.

High-intensity exercise releases the body’s feel-good chemicals called endorphins, resulting in the “runner’s high” a euphoric feeling that can be accompanied by a positive and energizing outlook on life. Dr. Michael Craig Miller, assistant professor of psychiatry at Harvard Medical School says that for most of us, the real value is in low-intensity exercise sustained over time. That kind of activity spurs the release of proteins called neurotrophic or growth factors, which cause nerve cells to grow and make new connections. The improvement in brain function makes you feel better. “In people who are depressed, neuroscientists have noticed that the hippocampus in the brain—the region that helps regulate mood—is smaller. Exercise supports nerve cell growth in the hippocampus, improving nerve cell connections, which helps relieve depression,” explains Dr. Miller.
