Patients with allergic rhinitis, such as that caused by hay fever and other allergies, have more difficulty sleeping and more sleep disorders than those without allergies, according to a report in the September 18 issue of Archives of Internal Medicine, a theme issue on sleep.
Allergic rhinitis, which occurs when pollen or other allergens irritate and inflame the nasal passages, affects about 20 to 50 percent of the population, according to background information in the article. Allergies have been shown to affect quality of life and several studies have suggested that they may contribute to snoring and breathing problems during sleep, including sleep apnea, a temporary halt to breathing. However, few researchers have closely examined sleep disorders in patients with allergic rhinitis.
