Nasal congestion, allergies, sinus infections, deviated septum, and physical exertion can cause a person to only breathe from one nostril.
nostril: orificio nasal; fosa nasal.

The condition of only being able to breathe through one nostril is called nasal congestion or nasal obstruction.
Nostrils are also known as nasal passages or nasal cavities.
It is common to alternate between breathing through one nostril at a time due to the nasal cycle, where one nostril becomes more dominant for a period before switching to the other nostril. This helps regulate airflow and maintain optimal nasal function.
Most people primarily breathe out of one nostril at a time, with the dominant nostril switching throughout the day in a cycle known as the nasal cycle.
It's serious. See a doctor. As for the cause there could be amny. A thin membrane in the nasal passage. Hemophelia. Who knows.
Nasal Cavity
Nostril windpipe (trachea)
Breathing through one nostril can occur due to several reasons, including nasal congestion from allergies, a cold, or sinus infection, which can cause swelling and block airflow. Additionally, the nasal cycle, a natural process where airflow alternates between nostrils, could make it seem like one nostril is more open than the other at times. If the blockage persists or is accompanied by other symptoms, it may be a good idea to consult a healthcare professional.
