People often feel “fuzzy headed” when they are congested. Studies have documented that children with untreated allergies perform worse in school. Nasal congestion affects the quality of sleep, which can lead to daytime lethargy. In addition, nasal inflammation triggers the release of cytokines which can affect the ability to think and perform.
There are many causes for nasal congestion. The most common causes are upper respiratory infections and allergies. Chronic nasal congestion may be due to a deviated nasal septum, nasal polyps, or chronic sinusitis.
Successful treatment of nasal congestion will not only clear your nose, it will clear your head!
