Clipping, tweezing, trimming…we go to great lengths to ensure that our unsightly nose hair isn’t visible to the casual passer-by. It turns out, though, that nose hair, or sinus cilia, has an important role to play in our overall health.
Nose hair – nature’s filter
Additionally, there are two kinds of “hair” in the nose…the course, clip-able kind that peeks out of our noses, and the microscopic hair-like cilia. Both kinds of hair are vital to respiration.
Nose hair filters particulate matter from the air. Additionally, the mucus layering this hair creates a sticky “trap” for allergens and molds. While it may be tempting to get rid of that nose hair, you do so at your own risk—people who de-hair their nasal passages too assiduously are at increased risk for sinusitis, allergies, and bloody noses.
How it works
As you inhale, the hair in your nose “beats back” towards your sinus cavity. At the same time, the cilia in your sinuses are “beating forward,” propelling the particulate-bearing mucus down your throat and into you stomach. These cilia are tiny, hair-like structures that are free-floating in the nose and sinus cavity. When they are healthy, they beat 14-16 times per second. Clippers and tweezers have no effect on these hairs, but they can be paralyzed or even killed off by diesel fumes, cigarette smoke, and other pollutants
Sluggish cilia are implicated in sinus infections, chronic sinusitis, and possibly even lung cancer—so get that air purifier you’ve been eyeing! And if you’re having sinus problems or any discomfort, contact us right away—and no, you shouldn’t clip your nose hair first.
Frequently Asked Questions
Nose hair acts as a natural filter by trapping particulate matter such as dust, allergens, and mold from the air we breathe. It works together with mucus to create a sticky barrier that prevents harmful particles from entering the respiratory system.
Yes, there are two types of hair in the nose: the coarse, clip-able hairs visible outside the nostrils, and the microscopic hair-like cilia inside the nasal and sinus cavities. Both types play vital roles in respiration and air filtration.
The cilia in the nose and sinuses beat rhythmically (14-16 times per second) to move mucus, which traps particles, down the throat and into the stomach. This movement helps clear the nasal passages and prevent infections.
Excessive removal of nasal hair can increase the risk of sinusitis, allergies, and nosebleeds. Nose hair is essential for filtering and trapping harmful particles, so removing it compromises the body's natural defenses.
Nasal cilia can be paralyzed or destroyed by exposure to diesel fumes, cigarette smoke, and other airborne pollutants. Damage to these cilia impairs mucus clearance, increasing the risk of sinus infections and other respiratory problems.
When cilia are sluggish or damaged, they cannot effectively move mucus, leading to accumulation and increased chances of sinus infections, chronic sinusitis, and possibly other serious conditions such as lung cancer.
No, clipping or tweezing visible nose hair does not affect the microscopic cilia, and excessive removal can actually increase the risk of sinus problems and nosebleeds. It's better to maintain natural nose hair and address sinus issues with appropriate medical advice.
