One Nostril Gets Congested at a Time Because of a Nasal Cycle
Nasal congestion, often known as a stuffy nose, is frequently a sign of another medical condition, like a sinus infection. You feel awful when you have allergies or illnesses like colds, and getting congested is one of the worst side effects. However, you might have noticed the peculiar situation of only experiencing congestion in one nostril at a time. Additionally, it might even change nostrils. What gives, then?
It seems that your nose is not a physical part with equal rights. Even during regular breathing, one nostril is primarily responsible for breathing. Throughout the day, it will swap back and forth, but your autonomic nervous system ensures that one is constantly working harder than the other.
Your nose won't dry out or become injured thanks to this nasal cycle. A cold or allergies will widen the blood vessels in the nose, causing more mucus to be produced. This will make one nostril feel congested while the other takes over.
