Nasal hair Nasal hair Nasal hair or nose hair is the hair in the nose. Adult humans have hair in the interior nasal passage. Nasal hair functions include filtering foreign particles from entering the nasal cavity and collecting moisture. In support of the first function, the results of a 2010 study indicated that increased nasal hair density decreases development of asthma in those who have seasonal rhinitis, possibly due to an increased capacity of the faces to filter out pollen and other allergens. Nasal hair should not be confused with cilia of the nasal cavity, which are the microscopic cellular strands that,
Nasal congestion allergies or the common cold. Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway. Often a doctor's assessment of a perfectly patent nasal airway might differ with a patient's complaint of an obstructed nose. Prevalence of kyphosis has been linked to nasal obstruction in a study. The treatment of nasal congestion frequently depends on the underlying cause. Alpha-adrenergic
