Nasal congestion, also known as rhinitis, is inflammation of nasal cavity linings. It causes swollen nasal passages and difficulty breathing. Symptoms include congestion, mucus buildup, and fatigue
Nasal congestion occurs when nasal membranes become inflamed and produce more mucus. Symptoms can be caused by colds, flu, allergies, or environmental irritants. Most cold-related congestion resolves within a few days
Gravity causes mucus to pool in nasal passages when lying down. Airborne allergens like pollen settle at night. Structural problems in nostrils increase congestion risk. Changes in cortisol levels affect symptoms of respiratory infections. Cold and dry air irritate nasal lining
Nasal congestion causes reduced airflow and fullness in the nose. More than one billion Americans get colds yearly with congestion. Affects one-quarter of world's population with allergic rhinitis
Treats nose stuffiness and runny nose. Should not be used for more than 3 days
Nasal congestion blocks passages, affecting breathing through nose. About 85% of cases lead to mouth breathing instead. Humans are designed to breathe through nose from birth. Can be caused by allergies, colds, sinusitis, or pregnancy. May result from narrow nasal valve or nasal polyps
