This study by Dutch researchers was published online in January by the journal Chest. The participants were 125 pairs of people who lived together. One member of each pair had COPD.
Overall, study participants with COPD were more sedentary than those they lived with. That comes as no surprise. People with COPD often experience shortness of breath during physical activity, which may discourage many from exercising.
However, when those with COPD lived with someone who was physically active, they engaged in more moderate- to vigorous-intensity activity themselves. That's important, because keeping moving is great for people with COPD. In a 2017 report from the Global Initiative for Chronic Obstructive Lung Disease, physical activity is recommended for helping manage COPD at every severity level. 2
