My nose smells ammonia. What's going on?

The nose always smells a smell of ammonia. Generally, it is related to long-term wearing of masks, environmental problems, nasal diseases, etc.

1. Long-term wearing of masks

During the epidemic period, many people need to wear masks for a long time. If the masks are not replaced or cleaned in time, it will lead to bacteria and dirt breeding inside the masks, thus producing ammonia odor.

2. Environmental problems

If there are too many detergents, furniture, floors and other items containing chemicals in the home, it is easy to cause ammonia odor in the indoor air.

3. Nasal diseases such

as allergic rhinitis, sinusitis and nasal polyps, etc., due to secretions decomposed by bacteria, or polyps erosion, can also cause nasal odor, which may be manifested as ammonia odor.
