A stuffy nose at night can be caused by several factors. It's often worse at night because of changes in body position and increased blood flow to the nasal passages.
Common Causes of Nighttime Nasal Congestion
-
Allergies: Exposure to allergens like pollen, dust mites, pet dander, and mold spores can trigger inflammation and increased mucus production, leading to nasal congestion. This is especially prevalent at night as allergens can accumulate in bedding and carpets. (Source: Avogel, Verywell Health, Top Doctors)

Respiratory Infections: Colds, the flu, and other respiratory illnesses cause inflammation and mucus buildup, resulting in a blocked nose, often worse at night due to gravity. (Source: Robitussin, Verywell Health)

Nasal Polyps: These benign growths in the nasal passages can obstruct airflow, causing congestion that is more noticeable when lying down. (Source: Verywell Health)

Dry Air: Low humidity levels can dry out nasal passages, leading to irritation and congestion. (Source: Verywell Health)

Gravity: When lying down, fluids and mucus accumulate in the nasal passages, worsening congestion. (Source: Omaha Sinus)

Dehydration: Lack of fluids can thicken mucus, making it harder to drain and leading to congestion. (Source: Robitussin)
-
Poor Air Quality: A bedroom with poor air quality, containing allergens such as pollen, dust mites, pet dander, and mold, can significantly contribute to nighttime nasal congestion. These allergens can reside in various places within the bedroom, including bedding, carpets, and furniture. (Source: Provided Reference)

Deviated Septum: A deviated septum, where the cartilage separating the nostrils is misaligned, can restrict airflow in one nostril, making it feel blocked, particularly at night. Some individuals may find sleeping on a specific side alleviates this. (Source: Mayo Clinic, Breathe Right)

Sleep Apnea: This sleep disorder involves pauses in breathing during sleep, and nasal congestion can be a symptom or a contributing factor. (Source: MedlinePlus)
