Nasal congestion can be extremely bothersome, but what if it's only one nostril that's blocked?
Doctors at the Cleveland Clinic explain that congestion in one nostril is usually not a cause for concern. It can occur naturally, as one nostril becomes congested while the other clears every four to six hours. This cycle, regulated by the nasal turbinates (the blood vessels in the nose), helps control airflow by alternating congestion between nostrils.

What Causes Nasal Congestion in One Nostril?
Several factors can lead to blockage in one nostril, such as sleeping on your side. The nostril facing downward tends to become more congested. Additionally, a deviated septum, where the cartilage in the nose is misaligned, can also cause persistent blockage in one nostril.
Other causes include chronic sinus infections, nasal polyps, allergies, irritants, or dry air. In children, foreign objects stuck in the nose can block one nostril.
When Does It Become a Concern?
While nasal congestion is common, persistent blockage in one nostril can sometimes indicate a more serious condition, especially if it's accompanied by difficulty breathing, facial pain, snoring, nosebleeds, or a reduced sense of smell. If any of these symptoms occur, it's advisable to consult a healthcare provider for further evaluation.
To alleviate the congestion, you might try using a humidifier, saline nasal spray, or taking a hot shower. Keeping your head elevated while sleeping may also help. While most cases of one-sided nasal congestion are not serious, it’s important to monitor any additional symptoms and seek medical advice if the congestion worsens or doesn't improve.
