Hay Fever
Hay fever, known medically as Seasonal Allergic Rhinitis, involves an allergic reaction to pollen from trees, grass and flowers. Normally your immune system fights off only those things that threaten your health, such as cold viruses, but an allergic person’s immune system releases the chemical histamine to fend off the presumed offender. Unfortunately, the side effects of histamine are the symptoms associated with allergies: a runny nose and sneezing, itchy nose and throat, watery red eyes, and congestion.
