Chronic Insomnia May Increase Asthma Risk
HealthDay News — Insomnia may increase the risk of asthma in adults, according to research published online February 1 in the European Respiratory Journal.
In an effort to understand the association between insomnia and the risk of incident asthma, Ben Brumpton, MD, from the Norwegian University of Science and Technology and Trondheim University Hospital, and colleagues enrolled 17,927 participants, aged 20 to 65, in a prospective study.
The researchers found that individuals who said they had difficulty falling asleep "often" or "almost every night" had a 65 and 108% increased risk, respectively, of developing asthma over 11 years. Participants who said they woke too early and couldn't get back to sleep "often" or "almost every night" had a 92 and 36% increased risk, respectively, of asthma. Those who had poor quality sleep at least once a week had a 94% increased risk of developing asthma.
"A key finding in our study is that those people with chronic insomnia had more than three times the risk of developing asthma, compared to those without chronic insomnia, which suggests that any changes in the body due to insomnia may accumulate and result in more severe harmful effects on the airways," Brumpton said in a news release from the European Lung Foundation.
