Exercise can bring important benefits for COPD patients

Exercise can help reduce anxiety and depression in people with chronic obstructive pulmonary disease (COPD).

A new study of 400 patients with the disease found higher amounts of physical activity were linked to an 11 percent lower risk of anxiety and a 15 percent lower risk of becoming depressed, that's according to researchers at the University of Zurich in Switzerland and the University of Amsterdam in the Netherlands.

Experts say these findings are significant since mental disorders are common among COPD patients.
