Why is Animal Dander an Asthma Trigger?
Last updated: November 2022
My partner and I recently went to visit my dad. The visit was brief, but unfortunately, my partner had to stay in the backyard for the majority of the time. He hung out outside because my dad has cats, and animal dander is a major trigger for his asthma.
My dad doesn’t just have 1 or 2 cats, he has a grand total of 8 cats! If animal allergies are a trigger for your asthma, my dad’s house is an absolute nightmare.
Since dander is so small, it easily sticks to furniture, carpet, and clothing. It can even float in the air with other dust particles. Since dander is so “sticky”, it can be carried into rooms that have never even had pets before. My partner has had an allergic reaction from sitting next to someone in school that had a cat at home.
Why is animal dander an asthma trigger?
Many people believe that the hair of cats, dogs, and other furry pets is what causes the allergic reaction. This is almost true. It is not actually the hair that is a trigger, but dander that falls from the hair. Dander contains a protein that causes an allergic reaction. When you inhale these proteins, your immune systems will react. Your body releases histamine, and then all the typical symptoms of an allergic reaction start to appear. Ever had an itchy, constricted throat, and watery, red eyes?
It may seem that the furrier the animal, the more of an allergic reaction you have. This is true in a sense; if the animal has thick fur or feathers, it makes it easier for animal dander to get trapped. Everyone has different degrees of an allergic response to dander.
Can you control your exposure to animal dander?
The best way to avoid dander is to obviously stay away from pets, but this is not always possible! There are several ways to control your exposure to dander.
Some pets may be kept cleaner than others, resulting in a lower amount of dander on the animal. You may find that animals that have fewer baths are more of a trigger for you. If you or another person in your life has a pet, bathing the pet more frequently may help reduce your allergic reaction.
A friend or family member might also offer to put their pet outside or in another room. While this is very kind, it may not be effective at all. As previously stated, animal dander is microscopic and easily sticks to furniture. Even if a pet isn’t in the room, their dander probably still is.
A friend or family member may also offer to vacuum before you come over. Vacuuming may rid of some of the triggering dander, but it can also be hard to completely do away with it. Dander can lurk in the couch cushions, under furniture, and on windowsills. Vacuuming may actually disturb dander, and cause it to float about the room. If you are planning on coming over to someone’s house within an hour or so, ask them not to vacuum right before. Vacuuming is best done a couple of hours in advance!
Animal dander and asthma
Knowing what animal dander is and why it is a trigger might help you manage your allergic reaction to it. Dander can definitely be a tricky trigger to navigate around! Keep in mind that everyone can have different degrees of an allergic reaction to dander. My partner can be very allergic to some dogs and most cats, but be totally fine around others.
Discuss with your doctor a plan for being around dander. Additionally, communicate this plan to your friends and family so they can help accommodate you!
