Nasal hair

Nasal hair or nose hair is the hair in the human nose. Its main function is to prevent particles from entering the lungs.

Etymology

The term "nasal hair" is derived from the Latin words "nasus" meaning nose and "capillus" meaning hair.

Function

Nasal hair functions as a defense system against harmful or foreign particles from entering the lungs. It traps dust, bacteria, and other airborne particles that could potentially cause harm if inhaled. The mucus produced by the nose also helps to trap these particles, which are then removed when the nose is blown or when the person sneezes.

Grooming

Grooming of nasal hair is a common practice in many cultures. This can be done using various tools such as tweezers, scissors, or specialized nasal hair trimmers. However, excessive removal of nasal hair can lead to increased risk of infections as the nasal cavity loses its primary means of trapping foreign particles.
