Why do I always hold swimming diving water nose?
Rhinitis has nothing to do with it. I even pinch the nose, no rhinitis people, the nose is also a little water.
I think you should not hold the nose, block the nasal cavity, when diving, people will swim to the bottom, water pressure will make the water more powerful into your nasal cavity, leading to the nose like choking water, very uncomfortable.
Not strictly nasal cause, you are in the air is accidentally sucked down. It is certainly a novice swim, slowly like a habit
