Some people unknowingly and habitually use their fingers to dig their nostrils while sitting and reading books or watching TV. This is a bad thing.
The nose is an important sensory organ for humans and animals. Our nose can smell the smell of flowers and the smell of fire. If the nose is not good, not only is life uninteresting, but also unsafe.
There are a lot of nose hairs in the nasal cavity, which can filter the air and prevent the dirty air from entering the lungs. In addition, the nasal mucosa in the nasal cavity can also play a protective role. When irritated, it will secrete nasal mucus and wash away the dirty things. Therefore, the nose is very important, and the inside of the nose is very delicate.
Some people have a bad habit of digging their noses. Hold your hand out to see if there is anything black in your nails. Know that your fingers are covered with bacteria, viruses and parasitic eggs, especially the most bacteria in your nails. Frequent digging of nostrils is very easy to get sick.
If the nose hair is dug out and cannot filter the air, the respiratory organs are prone to problems; there are many capillaries on the nasal mucosa, and digging the nostrils can easily damage the nasal mucosa. The bacteria on the fingers will take the opportunity to enter the wound, and you will always drag your nose Sometimes nosebleeds are easy.
In short, digging nostrils is a very unhygienic thing, which is very bad for our health. We can grow up healthily only if we develop hygienic habits.
