Just 20 minutes of walking a day can help people improve their mental health.
That’s according to researcher George Mammen, at the University of Toronto (U of T).
He recently co-authored a study of more than 26 years’ worth of research reports.
He says the reports show that someone who is physically active is less likely to become depressed later in their life.
Most scientists agree that regular exercise is important for people’s physical health. It can help prevent diseases like stroke, heart disease and cancer.
And previous studies have shown that exercise can help to treat depression.
