Congestion and sleep impairment in allergic rhinitis

Abstract

Allergic rhinitis is a disease with an increasing prevalence throughout the world that severely affects the quality of life of individuals suffering from it. Nasal congestion is the most common and bothersome symptom, and is often associated with sleep-disordered breathing, which is thought to be the reason for sleep impairment in individuals with rhinitis. The end result is a decrease in quality of life and productivity and an increase in daytime sleepiness. Treatment with intranasal corticosteroids has been shown to reduce nasal congestion. Data on sleep-related end points from clinical trials of intranasal corticosteroids indicate that this reduction is associated with improved sleep, reduced daytime fatigue, and improved quality of life. Other therapies, such as montelukast, also have a positive influence on congestion and sleep. This review examines nasal congestion and the associated sleep impairment of allergic rhinitis patients. It explores the adverse effects of disturbed sleep on quality of life and how these conditions can be reduced by therapies that decrease congestion.
