The function of nose hair

Nasal cavity is the gateway of respiratory tract and the channel for gas exchange between human body and the outside world.

Nose hair growing on the nasal mucosa is located at the forefront, like a sentry at the entrance of the respiratory tract, shouldering the mission of preventing dust and bacteria from entering the body with breathing. Any tiny dust that enters the nasal cavity can stick to prevent it from invading. Dust and bacteria blocked by nasal hair are stuck by mucus secreted by nasal mucosa, forming nasal mucus and discharging it from the body. The nasal mucosa can also secrete immunoglobulin A to destroy invading bacteria.

Large foreign bodies, such as insects and grass clippings, enter the nasal cavity. Nose hair not only blocks them, but also transmits information to the nervous system, causing sneezing and removing it.

Pulling out the nose hair is equivalent to removing the sentry guarding the breathing door. Dust and bacteria can enter the human body unimpeded, causing human diseases. While pulling out the nose hair, it also damages the mucosa where the nose hair grows.

Nose hair is also a tactile auxiliary receptor. Therefore, plucking nose hair, cutting nose hair and picking nostrils are all harmful.
