Well it seems the answer is Yes.
The Adult Allergy Unit, Department of Chest Diseases, Hacettepe University School of Medicine, Ankara, Turkey in their abstract stated:
To the best of our knowledge, this is the first report on this subject in the literature.
And I bet it is.
This study was in those with seasonal rhinitis. It appears the higher the nasal hair density the less you were likely to have asthma. The rate of asthma was 44.7, 26.2 and 16.7% in the few, moderate and many (hairy nostril) groups.
I wonder who counted the hairs to determine what grouping people fell into.
So grow your hair in your nostrils to keep your airways good people.
I love this research stuff.
