Types of Environmental Allergens

Environmental allergens are any substances in the environment that can cause the onset of an allergic reaction. Things like dust, grass and pet dander are considered environmental allergens, but other indoor substances can be just as irritating to the body. The following are some of the most common environmental substances that people are allergic to.

Foods

Certain foods are considered to be environmental allergens. Some people are so sensitive that they cannot even be in the same room where certain foods are being prepared. If they actually consumed these foods it could be deadly. Some foods that have been known to be allergens are milk, eggs, nuts, soy, shellfish, wheat and seafood.

Airborne Particles

Some of the most common environmental allergens are airborne particles. This includes dust, pollen, mold spores, mildew and pet dander. Those who are allergic to these allergens normally suffer from coughing, sneezing and itchy, watery eyes.

Chemicals

Certain chemicals that are used in our environment can also be allergens for some. This can include perfumes, cleaning products, pesticides, cigarette smoke and fumes from vehicle exhausts. Continuous exposure to these allergens may cause some people to have skin or mouth irritation or even respiratory problems.

Jewelry and Metals

Certain jewelry or metals can also cause an allergic reaction for those who may have extremely sensitive skin. Some people are allergic to gold and can only wear silver jewelry. Some are even allergic to the metals that are used in making coins. This type of reaction usually causes a red, itchy rash on the skin that is quite uncomfortable.
