Nose hair can protect the olfactory nerve from damage, make the nose smell all kinds of smells, and transmit the fragrance of food to the brain to stimulate appetite.
It can be seen that the role of nose hair is not small, so it should be protected. Don't cut it casually, especially don't pull it out, otherwise it will cause nasal vestibulitis, which will last for a long time and recur. Moreover, the nose hair will grow back after being pulled out or trimmed, so people who have the habit of pulling out nose hair still suggest quitting as soon as possible. Pulling nose hair can cause hair follicle inflammation, so it is recommended to be cautious. During this period, pay attention to light diet and prohibit spicy and irritating food.
The capillaries in the nose are very developed, as rich as cobwebs. In addition to the ventilation function, the nasal hair and mucosa in the nasal cavity also have the function of filtering and adsorbing dust and bacteria to prevent them from infiltrating into the human body, and the nasal mucosa is also very delicate. Therefore, it is easy to damage the nasal mucosa with fingernails, causing bleeding, which is also the main reason why many people often have nasal bleeding. "
There are many bacteria and viruses on people's nails. Pulling nose hair hard will damage hair follicles, and bacteria and viruses will take the opportunity to get into the damaged parts of nasal cavity, causing folliculitis. Because the nose is very close to the brain, it is in the "dangerous triangle" in medicine. Bacteria and viruses that cause folliculitis and furuncle in the nasal cavity can easily ascend into the skull and cause encephalitis.
