Spanish researchers have found that physical activity, even a small amount can improve the health of patients suffering from COPD. Those who engage in exercise and activity have fewer hospitalizations and have a lower risk of dying.

COPD is a group of diseases, very often caused by years of smoking that restricts the airway and makes breathing more difficult. Many patients are dependent on oxygen most of the day. This study found that even light activity like walking three days a week could help.
