Chronic Sinusitis and Weather Sensitivity
People with chronic rhinosinusitis often notice their symptoms change with the weather, and there are plausible reasons why. Persistent inflammation narrows the openings that let the sinuses equalize with outside air, so pressure changes are felt more easily. Cold, dry air irritates an already inflamed lining, humid weather feeds mold and dust mites, and storm systems stir up pollen and change air quality. The research on weather and chronic sinusitis is limited, and symptoms rarely come from a single factor. But tracking the weather alongside your symptoms, and keeping your baseline inflammation under control, can make those bad-weather days more predictable and less severe.
This guide explains how weather interacts with chronic sinus disease and what you can do about it.
