COPD linked to poor sleep

DUBLIN, Ireland – People with chronic obstructive pulmonary disease (COPD) are more likely to sleep poorly than their peers without the condition, a new study says. The study, published in Respirology, a medical journal, was conducted by researchers at St. Vincent’s University Hospital in Dublin, Ireland. Researchers found that low oxygen levels in arterial blood, which is caused by COPD, can damage sleep quality, and may lead to a host of other debilitating symptoms. “Patients with COPD frequently report fatigue, sleepiness and impaired quality of life,” said Walter McNicholas, a professor in the department of respiratory and sleep medicine at St. Vincent’s University.
