This is not uncommon and may get better on its own. The dominant nostril switches throughout the day This is called the nasal cycle So why do we rarely breathe out of both nostrils at once? Uncover why you often breathe through one nostril Explore the natural reasons for this unique bodily function and when it might indicate an issue.
When you become ill, one nostril may feel more blocked due to the natural nasal cycle, where congestion alternates between nostrils We might not realise it, but our bodies deliberately direct the airflow more through one nostril than the other, switching between nostrils every few hours A constant airflow can dry out the nostrils, which damages their lining, so giving one nostril a rest. The phenomenon of alternating nostril breathing is known as the nasal cycle This natural process occurs in most individuals and involves a rhythmic change in airflow through each nostril Typically, one nostril is more open while the other is slightly blocked, and this alternation can happen every 30 minutes to several hours.
This is a natural process where one nostril becomes more dominant in airflow while the other nostril reduces airflow. This cycle involves the unconscious, alternating congestion and decongestion of the nasal passages At any given time, one nostril is more open, allowing greater airflow, while the other becomes more congested due to increased blood flow to its turbinates. This is the process it uses to regulate air through your airways For most people, the body automatically moves between having one dominant nostril throughout the day That means you might only breathe through one nostril at a time
The key, though, is that with the nasal cycle, the body switches back and forth between nostrils. Some individuals may notice easier breathing through one nostril, while struggling to take breaths through the other due to the nasal cycle.
