One day I noticed that I was ready breathing through the left nostril. Some hours later, I observed that I was breathing through the right nostril but not the left one!
I wondered if anything was wrong with me.
Most of the time we use only one nostril while breathing. This happens because of alternate swelling and decongestion of some valve-like structures called turbinates in each nostril.
When one nostril swells the other one diminishes in swelling and allows passage of air. This gives a resting period to each nostril.
When we exercise or do brisk work we need more oxygen than usual. In such circumstances both nostrils open and we breathe through both of them simultaneously.
