Your entire body (especially your brain) loves physical activity. An analysis of 78 studies published in the Journal of Psychosomatic Research concluded that an inactive lifestyle produces unusual stress on brain chemistry. Small amounts of activity can actually offset this stress. A study published in the journal, Health Psychology, found that 10 minutes of moderate-intensity, physical activity (brisk walking) was sufficient to improve mood and reduce fatigue. Recently Johns Hopkins School of Medicine reported in its White Papers that “Taking regular walks is not just one of the best ways to keep your body healthy, but research now suggests that it keeps your mind healthy as well.” It’s becoming clear that even small amounts of physical activity can stimulate your brain to work better.
