According to a report in the January issue of Archives of Internal Medicine, chronic bronchitis is more likely to develop in habitual snorers.
From 2001 to 2003, Inkyung Baik, Ph.D., of the Korea University Ansan Hospital, Republic of Korea, and colleagues monitored 4,270 people—52% men, 48% women. The men and women gave demographic information, health conditions, family disease history and lifestyle, and how often they snored. They were re-interviewed every year through 2006, and were classified as developing chronic bronchitis if they reported having a cough and sputum on most days for at least three months per year, for at least two years.
314 people developed chronic bronchitis during four years of follow-up. Individuals who snored regularly were more likely to develop bronchitis than those who did not.
