Winter Sinus Season

When the sagebrush pollen is finished by the end of October, the pollen allergy ceases until next spring. The changeable fall weather, along with viral and other respiratory infections, combined with valley inversions can cause acute and chronic sinusitis, bronchitis, and asthma. Sinus infections are generally triggered by viral pharyngitis, causing a sore throat, persistent nasal congestion, coughing, headaches, and fatigue that lasts beyond the usual three to five days of common cold symptoms. The coughing can progress to asthma adding to this common cause of winter respiratory distress. At times the winter sinus season can be due to household allergens such as house dust, animal danders, or mold spores, but infection is the likeliest trigger. Infectious sinusitis is mainly prevalent in the cold winter season but can occur on a year-round basis.
