narrowed nasal passages

I often notice at night when I lay down to sleep I have a hard time breathing thru my nose. My right nostril seems almost blocked compared to my left. During the day it's better but I can tell there is still some airflow restriction. Maybe the lack of oxygen theory starts with how we are breathing...especially at night. I'm thinking of trying those breathe-rite nasal strips at night but I wonder if I may get addicted to them and can't fall asleep with them.

Also have the same, combined with on/off blocked one side of the nose throughout the day and massively increased mucus.

steam room, sauna, olive oil extract detox and nasal clean should assist
good luck

If none of the above help or a neti pot. You may want to look in to getting a CT scan done through your ENT. I fought with this for years and tried everything from cayenne nasal sprays to acupuncture. Nothing worked. Turns out I had blockages all over my face, a severe deviated septum, and turbinates that were lopsided. Had 2 surgeries and am 90% better.

You can also see about trying a med called Dymista. Its an intranasal steroid (doesnt get in to your bloodstream) that really helps.
