Some people who keep cats and dogs often have breathing problems. Once lung discomfort occurs, it is considered that animal hair is sucked into the lungs.
In fact, the human body has evolved for so long, and there must be measures to deal with the environment. Nose hair is one of the measures to deal with dusty hair. Most animal hair will be directly isolated by nose hair.
Nose hair will isolate the cat hair
The air usually has dust invisible to the naked eye floating. The function of nose hair is to isolate the dust. In fact, most of the dust can be isolated, how can cat hair be blocked by nose hair.
Nose hairs are arranged very finely. Objects larger than 10μm are usually isolated from the nose hair. The smallest cat hair is 20μm, so most cat hairs will be isolated outside the nose hair.
The unisolated cat hair will be discharged by the trachea.
The trachea is the second barrier to defend the lungs. There are very small fluff on the surface of the trachea, which can enter the trachea by accident. When we cough violently, it is usually when dust and hair enter the trachea. As long as there is a foreign body, the villi will be stimulated. During the coughing process, the strong wind and tracheal mucus will bring the foreign body out of the trachea. .
The hazard of cat hair is not as great as the haze
In fact, many people don’t know that cat hair is a very large object and it is difficult to enter the lungs, and it is smaller than it. The most harmful thing to the human body is the smog, which is easy to harm the body. People have survived in the smog environment, let alone cat hair. So people who plan to raise cats or have already raised cats don’t really need to worry about cat fur. .
