Feeling depressed or down? Don't automatically reach for an anti-depressant...do some yoga. These days, the typical treatment for depression comes in the form of a pill, which can often lead to serious side effects and dependency. Prior to modern drug companies, however, sages from the East discovered a method of calming the mind and soothing the spirit. These physical exercises, called "asanas," are what modern Westerners typically think of when they hear the term "yoga."
