Are you struggling with allergy symptoms? Well, so are 50 million other Americans. What’s interesting about that large number is that different people have different allergy triggers. The substance causing one of us to sneeze and wheeze may not affect another in the slightest.

Below you are going to find a list of the most common allergy triggers. As an allergy sufferer, you are probably getting your symptoms from one or more than one of these triggers.

Everyday List of Common Allergy Triggers

Good news: I have included a few helpful tips, so you can avoid that trigger as much as possible.

Common Allergy Triggers List


We hear a lot about pollen count during allergy season, but what is it exactly? Pollen is a substance that comes from the male part of a plant. It is used to fertilize the female part of the plant. While this is lovely for growing more plants, it is terrible for our allergies.

Completely avoiding it outdoors is hard to do, so wash your hair, clothes, and home frequently to reduce your indoor exposure to pollen.

Dust Mites

Here’s the #1 most common trigger. As gross as it may sound, these are actually microscopic bugs, so they can see you when you can’t see them. They live in fabric sources like your bedding, your couch, your curtains, or your rug. They eat your dead skin cells and can cause some people massive allergy symptoms.

Here’s a short, interesting video showing you more about these dust mites:

Attempt to control your home’s humidity level (at over 40% humidity, they really start to thrive), wash your sheets frequently, and exchange your carpet for hard flooring (wood/tile).

Pet Dander

A lot of people think pet hair is where their allergies come from. It’s actually the dander, which can be found in your pet's saliva and oil glands. Interestingly enough, it can take 2 years for dander to start affecting you – which is plenty of time for your four-legged friend to become a family member.

Do not let your pet into your bedroom, so you have no exposure during sleeping hours, and bathe him or her regularly. If you know you have allergies but want a dog, visit friends with different breeds to see which provide the least (or no!) symptoms.


Mold grows where it’s continuously wet. You shouldn’t assume there’s no mold when you don’t see clear signs of it. It still may be there. If you’re concerned, you can have a mold test performed, so you can deal with it. Otherwise, just stick to the prevention steps.

Keep air flowing in wet places. For example, run a fan and keep your door open when you get out of the shower, so all that moisture doesn’t sit in there all day. You may want to avoid buying a home with a basement – or, if you do, do not put a living room/bedroom setup down there.


While the same drug can make one person feel great, it can easily make another person have hives and throat swelling. Some of the most common medications that end in an allergic reaction include:

  • Antibiotics
  • Aspirin
  • Chemo drugs
  • NSAIDs
  • Sulfa Drugs

Always talk to your doctor about your allergies, so they don’t accidentally prescribe you something similar. Also, be very aware of your body any time you are trying a new medication – whether that be over-the-counter or prescription.


When we think of a latex allergy, we may only think about itchy, red, rashy skin, but it can actually be much more severe. Exposure to latex can cause hives, runny nose, wheezing, sneezing, and even anaphylaxis. Unfortunately, latex is found in many more places than a doctor’s glove: balloons, shoe soles, Band-Aids, paint, condoms, etc.

Do you research before you buy anything – make sure there’s no latex hiding. If you know your reaction is severe, wear a medical bracelet.


This one’s a bit gross – both cockroach droppings and pieces of dead cockroaches can be an allergy trigger for many people. They can pop up anywhere – especially if you live in a warmer climate. And once you’ve seen one, you should assume there are more lurking.

Try to keep your kitchen clean at all times to keep them from being attracted to your space. Repair any crack as soon as you find it.

Insect Stings

Some people have more of a reaction to insect stings than others. Signs of an allergic reaction would be swelling, redness, itching, or pain. A stronger allergic reaction called anaphylaxis could actually end your life, so if you have trouble breathing, you need to see a doctor immediately.

Cover your body in clothes when you are going outside – especially in buggy places and wear closed-toed shoes.

Cigarette Smoke

This trigger is not normally on a list for regular allergens, but it is absolutely a common trigger for both allergic symptoms as well as asthma symptoms. The fact that it is an irritant is the least of its concerns, as second-hand smoke is a known risk fact for lung cancer.

There is only one option for this one: you need to stop smoking and stay away from people who are smoking.

Top Food Allergy Triggers

Signs of a food allergy often include hives, trouble breathing, and swelling around your mouth. You may also experience some digestive problems like nausea, vomiting, or diarrhea. It is possible for a food allergic reaction to be quite serious, so see your doctor immediately if these symptoms pop up.

While you could be allergic to virtually any food, here are some of the top triggers:

  • Dairy
  • Shellfish
  • Nuts and Peanuts
  • Soy
  • Eggs
  • Wheat

Avoiding Your Allergy Triggers

Taking the steps I mentioned to limit your exposure to your allergy triggers can be a massive help in getting your symptoms under control. Another great step you can make is to take an all-natural allergy, asthma, and respiratory support.

These supplements should naturally reduce inflammation and block any histamine effects, including:

  • Quercetin
  • Boswellia Extract
  • Nettle Extract
  • Coleus Forskohlii Extract
  • N-Acetyl-L-Cysteine
  • Vitamin D

Taking this supplement can naturally support your airways, so these allergy triggers won’t be as big of a deal to your health as they normally would.
