According to new research exercise may boost the brain's natural antidepressants. Reuters reports:“Exercise is important for healthy psychological function,” claims Dr. Fuhrman. Well, is he right? I venture to say yes, but see for yourself.
The findings, published in the journal Nature Medicine, point to potential new ways to treat depression in people.
Studies have found that exercise can help ease depression symptoms, but the reasons for the benefit have not been clear. For the new study, scientists used a tool called a microarray to examine how exercise changed gene activity in the brains of mice.
They focused on a brain region known as the hippocampus, which has been implicated in mood regulation and in the brain's response to antidepressant medication.
The researchers found that mice that had a week's worth of workouts on a running wheel showed altered activity in a total of 33 genes, the majority of which had never been identified before.
