Allergic reactions usually occur when the immune system goes into fight mode to react against substances that may cause infections in the body. While an allergic reaction can be a food, nasal, eye or skin reaction, it can also be a symptom for other ailments like asthma, sinusitis, ear infections and others. The symptoms usually include rashes, watery eyes, itching, redness, sneezing and even nausea.

This usually blocks the histamine production in a body – which is a substance that creates allergic reactions in the body. One can also take anti allergy medicines during a seasonal change and avoid triggers.
