I used to have serious 鼻敏感when I was small.
I had running nose and "Kachi" whenever the tempreture changes, the air is dirty/dusty, or going in & out of the air-conditioned room. Soft toys, winter coat and quilt from the drawer really killed me.
Since the medicine cannot really cure my 鼻敏感, I tried exercising. Swimming really improves my 鼻敏感 a lot.
Finally, I get rid of 鼻敏感 after spending several years in Canada, the fresh air really helps.
