Seasonal changes can affect asthma in many ways including air temperature, cold and ‘flu viruses and changes in humidity and dust and pollen levels.

"Fall is my favorite season. It’s a break for my lungs between the hot, humid summer and dry, sub-zero winter. I usually get lucky in terms of my asthma. The weather usually helps me to breathe better.

But fall isn’t an easy season for everyone with asthma. Early fall is when new allergens are in the air, flu season begins, and kids are back in school sharing germs. It can be challenging to stay healthy through the fall and winter, and avoiding asthma triggers can be challenging.

Take these steps to breathe easier during the season change.

Talk to your doctor about your symptoms

Asthma symptoms can get worse depending on the weather and seasonal allergens. Some people with allergic asthma may find that their asthma and allergy symptoms worsen during the fall.

Ask your doctor if you need to change your medications to get through fall and winter more easily. They may recommend allergy medications or immunotherapy treatment to decrease your symptoms.

Also, keep your rescue inhaler nearby in case you need it, just like you do during the three other seasons.

Be prepared for flu season

The flu can be more severe if you have asthma, even if it’s mild or well-managed. People with asthma are at risk of developing serious flu complications.

Talk to your doctor about your flu risk and any preventive measures to avoid getting sick. You may also want to discuss any potential modifications to your treatment plan before the flu season is in full swing in your area.

Wash your hands regularly

Having a cold can worsen asthma symptoms due to coughing and congestion. One of the other best ways to stay healthy this fall is to wash your hands often.

The Centers for Disease Control and Prevention (CDC) recommends washing your hands with soap and water for at least 20 seconds:

• Before you prepare or eat foods
• After caring for someone who’s sick
• After using the restroom or changing a diaper
• After coughing, sneezing, or blowing your nose
• At other times when your hands might get germs on them, like after touching animals or taking out the garbage

I also try to avoid crowded areas like stadiums and shopping malls. (Hey, it’s still early enough to start holiday shopping online!)

Banish dust from your home

More time spent inside means more time spent with the allergens like dust mites, a common indoor asthma trigger.

Dust mites like humidity and temperatures between 68 to 77°F (20 to 25°C). That’s the same environment that feels nice to us humans. They can trigger allergies like sneezing and runny nose and asthma symptoms like wheezing and difficulty breathing.

Learning how to combat dust mites can help reduce asthma symptoms. Here are some tips:

• Vacuum regularly.
• Use dust-proof pillow and mattress covers.
• Wash bedding weekly at temperatures high enough to kill dust mites 130°F.
• Try to avoid wall-to-wall carpeting and wash carpets in hot water when possible.
• Reduce humidity to less than 50 percent using a dehumidifier.

Clean up after pets

Pet dander is another indoor allergen that can make asthma symptoms worse.

These steps can help reduce symptoms:

• Keep pets out of your bedroom.
• Vacuum regularly using a double-walled filter or micro-filter bag.
• Brush your pet outside frequently. Preferably not by you!
• Remove carpets, which can trap allergens.

Clean up the yard

Mold is an outdoor fall allergen that can trigger asthma symptoms. It doesn’t die off with the first frost and tends to grow in piles of dead leaves. Keep your yard well-raked and wear a mask if you’re doing the cleaning.

Stay indoors when pollen counts are high

Ragweed pollen is another outdoor allergen that sometimes triggers asthma symptoms in late summer and early fall. If pollen affects you, track pollen counts on your local news.

Try to stay indoors with the windows closed when pollen counts are high, especially between 10 a.m. to 3 p.m. If you have to go out, it’s a good idea to shower and change clothes when you come back inside. This can help decrease your exposure to pollen attached to your hair and body.

Taking steps to avoid allergens can help you navigate the challenges of living with asthma in the fall. That way, you can focus on the apple cider and pumpkin spice!
