You can rest assured that cat hair is generally not sucked into human lungs. The statement that there are 100,000 cat hairs in the lungs” is false, and you don’t need to pay too much attention to it.
Why doesn’t cat hair get sucked into the lungs?
This is mainly due to the special structure of the human respiratory tract. The process of air from nostrils to lungs needs to pass through four lines of defense: nasal hair, nasal cavity, nasal cilia and mucus layer. In the process of human breathing, most of the impurities in the air will be filtered out, ensuring that every breath of air you breathe is full of air. is clean. Under normal circumstances, only substances of 0.5μm~2μm can enter our bronchi, and substances smaller than 0.5μm can enter our lungs, and the smallest cat hair is 400 times larger than 0.5μm! Therefore, owners basically do not have to worry about whether there will be cat hair in their lungs. If you want to suck cats, suck cats (except those with cat hair allergies).
Will cat hair be eaten in the stomach?
Although cat hair will not run into the lungs, it is still possible to accidentally eat it into the stomach. Although most of the time, when there is hair in our mouth, we will have obvious strange feeling and can spit it out voluntarily. But if silky hair is mixed in with meals, it is generally not easy to feel when humans chew food.
Because cat hair is thinner and shorter than human hair, a small amount of cat hair may be swallowed into the stomach along with the food during our rapid chewing.
But owners don’t have to worry, the cat hair in the stomach can usually be excreted normally through the feces, and don’t worry that we will also have the same symptoms of hairballs
as cats.
In summary, cat hair will not have much impact on human beings except that it will stick to our clothes and furniture. On the contrary, cats are prone to serious cat hairball disease by licking their own hair every day. Therefore, for the sake of the cat’s health, the owner should regularly brush the cat’s hair and feed it with depilatory cream!
