About Healthy Noses

Healthy Noses is a plain-language library about the nose: dry nasal passages, nosebleeds, sinuses, allergies, smell, and the air we breathe at home.

Our sponsor

Healthy Noses is sponsored by Narisure, a nasal moisturizing oil created by Johns Hopkins–trained sinus specialists. Articles that discuss nasal dryness may mention Narisure, and product boxes are always labeled.

How articles are made

New articles are drafted with AI assistance from peer-reviewed studies indexed in PubMed and from public-health agencies. Each article lists its sources so you can read them yourself. We do not describe any product as a cure or treatment for disease.

Not medical advice

Nothing here replaces a visit to a clinician. Get care promptly for a nosebleed that will not stop after 20 minutes of firm pressure, bleeding after an injury, a sudden loss of smell, or symptoms on only one side that keep getting worse.
