Newswise — That midday wall you hit where you just can't stay awake may be an indicator of obstructed nasal passages and sleep-disordered breathing, according to a new study published in the October 2007 edition of Otolaryngology " Head and Neck Surgery.
Nasal obstruction is an upper airway condition that can be caused by a variety of maladies, such as allergies, rhinosinusitis, or a deviated septum.
According to the Japanese study, people with chronic nasal obstruction were twice as likely to experience excessive daytime sleepiness (EDS) than those without nasal obstruction. Furthermore, these patients were also five times more likely to suffer from habitual observed apnea (suspension of breathing during sleep), which may be a contributing factor to daytime sleepiness.
The study, which assessed 6,790 patients through self-administered surveys, also concludes that while nasal obstruction in itself is not life-threatening, the course of condition can severely impact a person's quality of life by negatively affecting their work and social activities.
