There are five types of anxiety disorders: panic, generalized, obsessive-compulsive, social phobia and post-traumatic stress. All exhibit cognitive and physical symptoms such as worrying, sweating, fear of doom, racing heart, dizziness, light-headedness, fast breathing, sense of choking and more.
Infections, allergies, changes in temperature or a weak immune system can cause sinuses to become inflamed and blocked, with symptoms such as headache, facial pressure, coughing, fatigue, achiness and fever.
A sinus infection can make your head feel fuzzy, lethargic or disconnected, and cause your cognitive symptoms to worsen. Sinusitis can exaggerate a sense of depersonalization---not feeling real or connected.
Recurring sinus infections or those lasting four to eight weeks are chronic, according to the Centers for Disease Control and Prevention, and can be caused by a weakened immune system, deviated septum (crooked separation between right and left nostrils) or nasal polyps.
Link Between the Two
Anecdotal evidence indicates that people with chronic sinus infections are also inclined to have anxiety, but no scientific evidence of a link exists. As Serena Gordon writes on Anxietytribe.com, just sneezing makes people worry about the flu and dying---being sick only enhances worry.
If you are prone to anxiety, a sinus infection can intensify symptoms. If you have never experienced anxiety before, chronic sinusitis might trigger it for the first time.
