Allergic and nonallergic rhinitis: the threat for obstructive sleep apnea

Both AR and NAR are risk factors for a high apnea-hypopnea index, and both can predispose to sleep apnea. However, NAR seems to have a greater risk according to impaired polysomnography results and higher Epworth Sleepiness Scale scores. Therefore, patients with rhinitis should be treated not only for nasal symptoms but also for a better quality of sleep.
