If you suffer from allergies, you know how debilitating they can be. Common allergy symptoms can include sneezing, runny nose, itchy eyes, and more.

But what causes allergies? There are many different things that can trigger an allergic reaction, but here are six of the most common:.

Pollen

Pollen is one of the most common allergy triggers. It is a fine powder that is released by plants during their reproductive cycle. Pollen is transported by wind, insects, and animals, and can be found in the air, on surfaces, and in water.

When people come in contact with pollen, their bodies may react by producing antibodies that trigger allergy symptoms like sneezing, itchy eyes, and runny nose. You can minimize your exposure to pollen by staying indoors during peak pollen times, keeping your windows closed, and using an air filter.

Dust Mites

Dust mites are tiny bugs that live in dust. They are one of the most common allergens found in homes. Dust mites thrive in warm and humid environments, and can be found in bedding, furniture, and carpets.

When people come in contact with dust mites, their bodies may react by producing antibodies that trigger allergy symptoms like sneezing, itchy eyes, and runny nose. You can minimize your exposure to dust mites by washing your bedding in hot water, vacuuming regularly, and using dust mite covers on your mattress and pillows.

Mold

Mold is a type of fungus that can grow indoors and outdoors. It thrives in warm and humid environments, and can be found in damp areas like basements, bathrooms, and kitchens.

When people come in contact with mold, their bodies may react by producing antibodies that trigger allergy symptoms like sneezing, itchy eyes, and runny nose. You can minimize your exposure to mold by keeping your home dry and well-ventilated, fixing any leaks or water damage, and using a dehumidifier.

Pet Dander

Pet dander is the dead skin cells, hair, and saliva of animals. It is a common allergen for people who are allergic to animals.

When people come in contact with pet dander, their bodies may react by producing antibodies that trigger allergy symptoms like sneezing, itchy eyes, and runny nose. You can minimize your exposure to pet dander by keeping your home clean, vacuuming regularly, and washing your hands frequently.

Food

Food allergies are becoming more and more common. Some of the most common food allergens include peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish.

When people come in contact with these foods, their bodies may react by producing antibodies that trigger allergy symptoms like nausea, hives, and anaphylaxis. You can minimize your exposure to food allergens by reading food labels carefully, avoiding cross-contamination, and carrying an epinephrine pen if you have a severe allergy.

Insect Stings

Insect stings are another common allergy trigger. Bees, wasps, hornets, fire ants, and yellow jackets are all insects that can cause allergic reactions.

When people are stung by these insects, their bodies may react by producing antibodies that trigger allergy symptoms like swelling, hives, and anaphylaxis. You can minimize your risk of being stung by wearing protective clothing, avoiding sweet-smelling perfumes and lotions, and staying away from areas where insects are known to nest.
