Fall Allergies Survival Guide: Causes, Symptoms, Remedies, Preventions

Prepare yourself for the fall allergy survival guide.

As a fall allergy sufferer myself, I created this guide to take us through the causes, symptoms, treatments, and how to avoid fall allergies for the whole season!

Get ready to make Autumn great!

What Are Fall Allergies, Are They Even Real?

Fall allergies are seasonal allergies that you experience in Autumn, and yes they are real.

Fall allergies tend to start around September and do not end until late October or early November.

How Common Are Fall Allergies?

Fall allergies fall into the blanket term of “seasonal allergies”.

According to the Asthma and Allergy Foundation of America, over 50 million Americans experience allergies each year.

You could divide the 50 million by the four seasons and come up with 12.5 million… but that isn’t necessarily accurate.

Autumn Allergy Causes

There are many factors that can cause you to experience allergies in the fall. Knowing the most common triggers will help you find out what is causing your symptoms.

Common Fall Allergy Triggers

common fall allergy triggers infographic - Ragweed pollen, ragweed is the biggest fall allergy trigger; mold spores, increased moisture promotes mold growth' tree leaves, tree allergies are triggered when you play, rake, and burn leaves' indoor allergens, spending more time indoors and dirty furnace filters can trigger allergies.

Ragweed Pollen

The biggest fall allergy trigger is Ragweed. Ragweed pollen levels are the highest in late summer to early fall.

The reports that ragweed pollen affects up to 15% of the U.S. Population

Ragweed is found in most of the United States, as well as Canada.


Depending on where you live, mold may be the reason for your fall allergy symptoms. Cooler temperatures and an increase of moisture from rain promotes mold and mildew growth


Fallen leaves are a common allergy trigger in Autumn, especially if you have an allergy to the tree. When the leaves fall, we play in them, get out the leaf blower, and possibly burn the pile of dead leaves. All of these can trigger your fall allergies.

Indoor Allergens

Indoor allergens like dust mites, and even dander, can be worse in the fall months. In the fall the weather is getting chilly, so you turn on that potentially dusty heater.

The HVAC system is now blowing the dust and possible pet dander all throughout the house.

Additionally, we tend to stay indoors longer in the fall months, and depending on your specific allergy, this indoor time can make your symptoms worse.


Symptoms of Fall Seasonal Allergies

Seasonal fall allergy symptoms are the same as allergies in any other season. These symptoms include:

  • Stuffy or Runny Nose
  • Itchy, watery eyes
  • Postnasal drip
  • Cough
  • Hives
  • Wheezing
  • Itchy Throat
  • Tiredness

How are Fall Allergies Diagnosed?

Allergies to include fall allergies are diagnosed by a physician, allergist, or ENT specialist. These medical professionals will conduct one of the following tests.

Allergy Diagnostic Tests

  • Patch Test
  • Bloodwork (IgE)
  • Scratch Test (Skin Prick Test)
  • Intradermal Skin Test
  • Supervised Challenge Test

Knowing what is causing your allergies is a great starting point to knowing how to fix your symptoms as well as how to prevent them entirely.

Have a chat with your doctor to find out more.

Fall Allergen Remedies & Preventions

Fall allergy symptoms can usually be managed, and in some cases prevented altogether.

Here are some great options to consider when fighting fall allergies.

Natural Fall Allergy Home Remedies

Nasal Rinse

A nasal rinse like a Neti-pot or nasal lavage uses natural saline to rinse your nasal passages and sinuses to flush out any allergens hanging out.

Take A Shower

Taking a shower when you come inside for the day or before you go to bed will rinse off the pollen trapped on your skin or in your hair.

Also, a steamy shower can help break up any mucus buildup and clear out those sinuses.

Wear a Mask

A mask when you are outdoors this fall will block a majority of mold spores and pollen from reaching your nose and lungs.

If you are seeing an increase in allergy symptoms when you are outside, this may be the quickest and easiest way to limit your symptoms.

Remember to wash your mask often to remove the allergens


Avoiding what you are allergic to is the #1 way to prevent fall allergies, it is also the hardest option to enforce. If you can do it, do it.

Frequent Cleaning

Cleaning and dusting will remove those pesky dust mites, dander, and pollen that are hanging out in your home.

Carpets are a massive collection area for allergens, ensure you are also vacuuming often.

I highly recommend a vacuum with a HEPA filter so you do not blow the allergens all around the house.

Here is a great-rated, and reasonably priced HEPA vacuum option.

Take off Your Shoes

Your shoes track in dirt, mud, and allergen! Taking off your shoes when you come into the house will keep allergens from spreading throughout your living areas.

Change Your Clothes

Clothes tend to be a nice and grabby surface for allergens to hang out. Changing your clothes when you come inside will keep you from contaminating the couch, bed, carpets, and rugs with pollen.

Additionally, changing your clothing will remove the allergens that are literally hanging out on your body, right under your nose.

Use A High-Efficiency Particulate Air (HEPA) Filter

A HEPA filter in your home will remove allergens like pollen, dust, mold spores, and dander that is in the air.

Our family has had great success with our WINIX HEPA filter. Check out my review here, WINIX PlasmaWave 5500-2 True HEPA Air Purifier Review

Fall Allergy Treatments


If you don’t currently take allergy medication, your doctor will probably start with an antihistamine to relieve your symptoms.


Congested, stuffy, or runny noses may find relief with taking a decongestant.

Allergy Shots

Immunotherapy isn’t for everyone but it does have a pretty good track record of working. Allergy shots can take years to be fully effective, but it may be worth a shot.

I have been getting shots for 2 years now, and I have had a positive experience.

Nasal Sprays

Steroid nasal sprays might be recommended by your doctor to help with sinus-like symptoms. These sprays take about 2 weeks to really show benefits.
