Many shovelers want to ask if raising cat hair will suck it into their lungs? Actually, it won’t be because cats are rough and don’t easily enter their lungs. However, cat hair may contain some tiny dust, and if you often hold the cat and play with it, they may enter your lungs and cause an allergic reaction. So, to protect your lung health, it is best to clean your cat regularly and keep the indoor air clean.
Cat hair is difficult to inhaled into the body and lungs because air generally enters the body from the nasal cavity, and there are cilia in the nasal cavity and trachea, which can block particles with a diameter of more than 10 microns. Therefore, unless a person deliberately inhales vigorously in places with a lot of cat hair, the cat hair will basically not be inhaled into the human body, let alone cause harm to people.
Some people have an allergic reaction to cat hair. If there are allergic people at home, once they have close contact with the cat, the allergens on the cat's hair will cause an allergic reaction to adults or children, and in severe cases may also cause asthma.
