Is Pulling Out a Nose Hair Harmful?

Nasal hair is a special type of hair that serves as a tactile auxiliary receptor and is the first line of defense against respiratory system diseases. It can block dust and bacteria in the air, maintain the temperature of the nasal mucosa, and protect the olfactory nerve from damage. This allows the nose to detect various odors and transmit the aroma of food to the brain, which can enhance appetite.

Pulling out nasal hair can be harmful to the human body. Nasal hair maintains the temperature and humidity of the nasal cavity and blocks dust and other foreign objects. Removing nasal hair can lead to nasal infections and other diseases, potentially damaging the hair follicle structure and leading to chronic rhinitis. Additionally, pulling out nasal hair can easily cause infections, which may even lead to intracranial infections.

Nasal hair is a special type of hair that grows inside the nose and serves as the first line of defense against respiratory system diseases. It can block dust, bacteria, and other particles in the air, allowing the body to inhale filtered, clean air. Nasal hair can completely block particles larger than PM50.

Nasal hair serves as the first line of defense against respiratory system diseases and has three main functions: (1) It blocks dust, bacteria, and other particles in the air, allowing the body to inhale filtered, clean air. Additionally, the cilia inside the nose help to trap some bacteria and transport them into the stomach, where they are killed by stomach acid. (2) Nasal hair maintains the temperature of the nasal mucosa, preventing cold air from entering the trachea directly and keeping the nasal mucosa moist. This helps to prevent dry or atrophic rhinitis and nasal bleeding. (3) Nasal hair protects the olfactory nerve from damage, enabling the nose to detect various odors and transmit the aroma of food to the brain, thereby enhancing appetite. If larger foreign objects, such as insects, enter the nasal cavity, nasal hair not only blocks them but also sends signals to the nervous system, causing sneezing to expel them.
