ORLANDO, FL-Just how much of the nose plays a role in sleep-disordered breathing should probably get a bit more attention. A new study suggests that there may be such a thing as sleep-disordered nasal breathing, and that nasal congestion significantly worsens during the rapid eye movement (REM) stages of sleep.

Whether the nasal airway causes sleep-disordered breathing is somewhat controversial and not really perfectly characterized, but we do believe that in some or many patients, the nose does contribute to sleep-disordered breathing, said Luc G.T. Morris, MD, an otolaryngologist at the New York University School of Medicine, at an ARS session.

Studies in the medical literature show that sleep stage is important to sleep-disordered breathing-most obstruction events occur during REM sleep. But the relationship between REM and what happens in the upper airway is not completely clear, he said.
