You know that exercise can chase off the blues. But for the first time, researchers have discovered that just a 30-minute walk can give a temporary lift from even major depression.
Researchers at the University of Texas at Austin asked 40 men and women recently diagnosed with major depression to walk on a treadmill or rest quietly in a comfy chair. After a half hour, both groups had fewer negative feelings, such as anger, fatigue, and tension, but only the exercisers said they actually felt good.
The walkers got an 85% boost in vigor (liveliness) and a 40% improvement in well-being. The lift lasted about an hour.
Past studies have shown that aerobic exercise increases the brain's levels of serotonin, a feel-good chemical. People also get an extra boost and a sense of accomplishment by knowing that they've done something good for themselves.
