Exercise for Relief from Anxiety - How Does it Work?

Gretchen Reynolds writes for the New York Times blog about the positive effect of exercise on anxiety.  She summarizes the work of Schoenfeld et. al whose studies* with mice suggest that regular exercise leads to an increase in healthy, calming neurons (GABA) in a part of the brain that helps us process emotions (hippocampus).  More evidence that behavior therapy ( CBT ) tools, such as jogging, taking brisk walks, or working the treadmill, are an effective way to increase feelings of calm in both the long and short term.
