What Causes a Stuffy Nose?
Sinus infections, or sinusitis, occur when the cavities around the nasal passages become swollen and inflamed, often due to an infection. This inflammation can block mucus drainage, leading to pain and a stuffy feeling, which can sometimes be alleviated with an air purifier that helps reduce airborne irritants.
