Brief Summary:
Whether impaired nasal breathing contributes to sleep related breathing disturbances has not been known. Therefore, the purpose of the study is to compare the effect of xylometazoline, a drug that decongests the nasal mucosa when applied locally, with placebo in terms of sleep and nocturnal breathing and daytime performance.
