There are different allergy types that one needs to be aware of. Educating oneself about this can help one avoid allergens effectively.

What is an allergy?
An allergic reaction takes place when the immune system perceives something foreign as danger. As a result, it causes a reaction like coughing, sneezing, vomiting, diarrhea, itching, etc. This happens when your body is trying to get rid of the allergen.

For instance, pollen grains can cause the body to produce excess mucus, which is expelled through coughs and sneezes. This would be seen as hay fever or rhinitis. Similarly, consuming food that the immune system finds dangerous can lead to vomiting as the body tries to expel this substance. Certain things can cause allergies in a person. Identifying such things and avoiding them is the best way to overcome these situations.
